Enhancement of local pairing correlations in periodically driven Mott insulators

Francesco Peronaci, Olivier Parcollet, and Marco Schiró

Phys. Rev. B 101, 161101(R) (2020) - Published 1 April, 2020

Periodically driving strongly correlated systems offers new opportunities to control their properties. Heating effects, however, often hinder the actual realization of interesting states. Here, the authors study a model of a Mott insulator with a time-periodic Hubbard on-site potential U coupled to a dissipative reservoir. Tuning the frequency above a characteristic value, they unveil a regime where the creation of doublon-holon excitations is greatly enhanced with respect to equilibrium. Below a certain effective temperature, this far-from-equilibrium state would give rise to the exotic η-pairing superconduting state.

Gapless Dirac surface states in the antiferromagnetic topological insulator MnBi2Te4

Przemyslaw Swatek, Yun Wu, Lin-Lin Wang, Kyungchan Lee, Benjamin Schrunk, Jiaqiang Yan, and Adam Kaminski

Phys. Rev. B 101, 161109(R) (2020) - Published 16 April, 2020

A topological insulator can be converted to an axion insulator when time reversal symmetry is broken, which leads to the opening of a gap in the Dirac surface state. Recently, MnBi2Te4 was predicted to host such a state upon antiferromagnetic ordering. Collecting and analyzing very detailed photoemission data, the authors demonstrate that this does not occur and that the Dirac surface state remains gapless well below the Néel temperature. Most likely, this is due to the complexity of the magnetic ordering at the surface. The quest for the discovery of an axion insulator is, therefore, still on.

Lattice dynamics in the spin-12 frustrated kagome compound herbertsmithite

Ying Li, A. Pustogow, M. Bories, P. Puphal, C. Krellner, M. Dressel, and Roser Valentí

Phys. Rev. B 101, 161115(R) (2020) - Published 24 April, 2020

Distorting a crystal affects its magnetic properties; vice versa, magnetic interactions can influence the lattice and its vibrations. By probing optical phonons – quantized sound waves excited by infrared radiation – we identify changes in the crystal symmetry related to the magnetic ground state of the widely studied quantum spin liquid candidate herbertsmithite. We determine the atomic motion of all 54 phonon modes and specify a possible symmetry breaking associated with the slowest phonons, providing insight into the coupling of magnetic and structural properties.

Observation of strong higher-order lattice anharmonicity in Raman and infrared spectra

Xiaolong Yang, Tianli Feng, Joon Sang Kang, Yongjie Hu, Ju Li, and Xiulin Ruan

Phys. Rev. B 101, 161202(R) (2020) - Published 6 April, 2020

It has been well-known that Raman and infrared linewidths are associated with third-order lattice anharmonicity. Here, the authors go further and establish by means of first-principles calculations and Raman measurements that the previously neglected fourth-order anharmonicity may play a significant, or even dominating, role. The predicted strong fourth-order lattice anharmonicity results from the large four-phonon scattering phase space of zone-center optical phonons. It explains well the significantly broadened Raman or infrared peaks, observed for a wide range of materials at various temperatures. This finding may significantly impact spectroscopy techniques and the understanding of radiative transport.

Interplay of excitonic complexes in p-doped WSe2 monolayers

Sven Borghardt, Jhih-Sian Tu, Takashi Taniguchi, Kenji Watanabe, and Beata E. Kardynał

Phys. Rev. B 101, 161402(R) (2020) - Published 7 April, 2020

Photoluminescence from WSe2 monolayers reflects its rich system of excitonic complexes. Here, the authors explore the surprising competition between the formation of bright and dark trions at different concentrations of a hole gas in the monolayer. The competition, which leads to the most intense neutral exciton signal at nonzero hole doping, is explained by the screening of disorder by the free charge carriers and the hole-concentration dependent scattering rates of neutral excitons into bright trions.

Quantum scars as embeddings of weakly broken Lie algebra representations

Kieran Bull, Jean-Yves Desaules, and Zlatko Papić

Phys. Rev. B 101, 165139 (2020) - Published 27 April, 2020

Recently, much effort has focused on understanding weak ergodicity breaking in many-body quantum systems that could lead to wavefunction revivals in their dynamics far from equilibrium. An example of such nonthermalizing behavior is the phenomenon of quantum many-body scars, which has been experimentally observed in Rydberg-atom quantum simulators. Here, the authors show that many-body scars can generally be viewed as forming approximate subspaces of “broken” Lie algebra representations. Furthermore, they use an iterative process to identify perturbations which “correct” the broken Lie algebra, resulting in improved quantum revivals from special initial states. The description of embedded Lie algebra representations unifies several theoretical models, which feature exact many-body scars, with experimentally realized models, such as the constrained Rydberg-atom system, where scars only form an approximate Lie algebra representation.

Transient optics of gold during laser irradiation: From first principles to experiment

A. Blumenstein, E. S. Zijlstra, D. S. Ivanov, S. T. Weber, T. Zier, F. Kleinwort, B. Rethfeld, J. Ihlemann, P. Simon, and M. E. Garcia

Phys. Rev. B 101, 165140 (2020) - Published 27 April, 2020

The reflectivity of noble metals can dramatically change upon ultrashort laser irradiation due to the heating of d electrons to high temperatures. Knowledge of the resulting transient optics is fundamental for determining and controlling the absorbed energy. In this work, high-accuracy self-reflectivity measurements are performed and interpreted using a theory for the space-resolved and time-resolved energy absorption and dissipation. The combined approach yields the reflectivity of gold in dependence on the incident laser fluence for a wide spectral range.

Searching for fracton orders via symmetry defect condensation

Nathanan Tantivasadakarn and Sagar Vijay

Phys. Rev. B 101, 165143 (2020) - Published 29 April, 2020

Fracton phases are exotic quantum states of matter that are characterized by the presence of pointlike excitations with fundamentally restricted mobility. Important open questions remain about how to characterize the universal properties of distinct types of fracton order when viewed as conventional quantum phases. The authors provide substantial progress towards answering this question by deriving constraints on the ground-state wavefunctions of fracton phases, which generalize the string-net equations used to characterize two-dimensional topological order. These constraints yield new types of fracton order, and provide a starting point for characterizing their essential data.

Quantum Hall criticality in Floquet topological insulators

Kun Woo Kim, Dmitry Bagrets, Tobias Micklitz, and Alexander Altland

Phys. Rev. B 101, 165401 (2020) - Published 1 April, 2020

Topological Floquet Anderson Insulators (TFAIs) are systems in which an interplay of topology, driving, and static disorder stabilizes a unique form of topological quantum matter. Here, the authors present a first-principles theory, describing the topological phases and quantum criticality of the two-dimensional TFAIs in symmetry class A. Within this framework, they demonstrate how disorder is key to the formation of topological quantization, and that its critical behavior is in the quantum Hall universality class.

Phys. Rev. B 101, 165139 (2020) - Published 27 April, 2020

Recently, much effort has focused on understanding weak ergodicity breaking in many-body quantum systems that could lead to wavefunction revivals in their dynamics far from equilibrium. An example of such nonthermalizing behavior is the phenomenon of quantum many-body scars, which has been experimentally observed in Rydberg-atom quantum simulators. Here, the authors show that many-body scars can generally be viewed as forming approximate subspaces of “broken” Lie algebra representations. Furthermore, they use an iterative process to identify perturbations which “correct” the broken Lie algebra, resulting in improved quantum revivals from special initial states. The description of embedded Lie algebra representations unifies several theoretical models, which feature exact many-body scars, with experimentally realized models, such as the constrained Rydberg-atom system, where scars only form an approximate Lie algebra representation.

The reflectivity of noble metals can dramatically change upon ultrashort laser irradiation due to the heating of d electrons to high temperatures. Knowledge of the resulting transient optics is fundamental for determining and controlling the absorbed energy. In this work, high-accuracy self-reflectivity measurements are performed and interpreted using a theory for the space-resolved and time-resolved energy absorption and dissipation. The combined approach yields the reflectivity of gold in dependence on the incident laser fluence for a wide spectral range.

Phys. Rev. B 101, 165143 (2020) - Published 29 April, 2020

Fracton phases are exotic quantum states of matter that are characterized by the presence of pointlike excitations with fundamentally restricted mobility. Important open questions remain about how to characterize the universal properties of distinct types of fracton order when viewed as conventional quantum phases. The authors provide substantial progress towards answering this question by deriving constraints on the ground-state wavefunctions of fracton phases, which generalize the string-net equations used to characterize two-dimensional topological order. These constraints yield new types of fracton order, and provide a starting point for characterizing their essential data.

Quantum Hall criticality in Floquet topological insulators

Phys. Rev. B 101, 165401 (2020) - Published 1 April, 2020

Topological Floquet Anderson Insulators (TFAIs) are systems in which an interplay of topology, driving, and static disorder stabilizes a unique form of topological quantum matter. Here, the authors present a first-principles theory, describing the topological phases and quantum criticality of the two-dimensional TFAIs in symmetry class A. Within this framework, they demonstrate how disorder is key to the formation of topological quantization, and that its critical behavior is in the quantum Hall universality class.
