Crystal-to-fracton tensor gauge theory dualities

Michael Pretko, Zhengzheng Zhai, and Leo Radzihovsky

Phys. Rev. B 100, 134113 (2019) - Published 30 October, 2019

Fractons are a new class of emergent quasiparticles with restricted mobility. Previously, fractons were only known to occur in complicated spin models without direct material realization. Here, the authors detail various duality relationships, which map directly the physics of fractons onto topological defects of quantum crystals. Fractons and dipoles correspond to disclinations and dislocations, respectively, while elastic phonons map onto tensor gauge modes. The authors discuss several applications of the duality, such as a simplified reformulation of two-dimensional melting.

Entanglement transitions from holographic random tensor networks

Romain Vasseur, Andrew C. Potter, Yi-Zhuang You, and Andreas W. W. Ludwig

Phys. Rev. B 100, 134203 (2019) - Published 9 October, 2019

Universal features in patterns of entanglement of quantum states provide valuable information-theoretical insights into complex quantum many-body phases and dynamics. This work uncovers a novel class of phase transition between weakly- and strongly- entangled quantum states, described holographically at the boundary of a random tensor network. The univeral scaling structure of these transitions is explored via an exact mapping onto a classical spin model, which also opens the door to efficient numerical methods to study these complex quantum phenomena.

Measurement-driven entanglement transition in hybrid quantum circuits

Yaodong Li, Xiao Chen, and Matthew P. A. Fisher

Phys. Rev. B 100, 134306 (2019) - Published 15 October, 2019

Quantum information tends to spread out in interacting systems, leading to thermalization as characterized by the volume-law entropy of entanglement, while local measurements that extract classical information of the state tend to interrupt the propagation of information and reduce the entanglement entropy. Can entanglement sustain repeated measurements? The authors address this question in a toy hybrid-circuit model, where qubits undergo both unitary time evolution and sporadic local measurements. The phase diagram features a stable volume-law phase of entanglement for weak measurements and an area-law phase for strong measurements. The two domains in the diagram are separated by a single second-order phase transition. Characterization of both phases as well as of the critical point are presented.

Magnetic order in Nd2PdSi3 investigated using neutron scattering and muon spin relaxation

M. Smidman, C. Ritter, D. T. Adroja, S. Rayaprol, T. Basu, E. V. Sampathkumaran, and A. D. Hillier

Phys. Rev. B 100, 134423 (2019) - Published 17 October, 2019

Rare-earth intermetallics can exhibit complex magnetic phases, driven by competing interactions. Here, the authors use neutron scattering and muon-spin relaxation to show that Nd2PdSi3 is one such example, where there are both ferromagnetic and antiferromagnetic components to the magnetism and they coexist microscopically across the whole sample volume. The intensity of the antiferromagnetic Bragg peaks features an unusual temperature dependence, reaching a maximum at intermediate temperatures, while at low temperature the system approaches uniform ferromagnetism. These results may help understand the skyrmion phase very recently observed in isostructural Gd2PdSi3.

Probing the many-body localization phase transition with superconducting circuits

Tuure Orell, Alexios A. Michailidis, Maksym Serbyn, and Matti Silveri

Phys. Rev. B 100, 134504 (2019) - Published 7 October, 2019

Chains of superconducting devices provide a natural platform for exploration of synthetic bosonic quantum matter, and the possibility to tune parametric disorder in situ makes them an ideal framework for the study of localization physics in particular. Here, the authors demonstrate that by tuning disorder strength via external magnetic field, one can probe both ergodic and many-body localized phases in a disordered bosonic Hubbard model. Simulations of time evolution suggest that coherence times of currently available devices are sufficiently long to distinguish between the two phases using the temporal fluctuations of local occupations.

Exceptional points in tunable superconducting resonators

Phys. Rev. B 100, 134505 (2019) - Published 7 October, 2019

Exceptional points enable the fastest possible dissipative energy transfer between quantum systems and, hence, are potentially required in optimal cooling of qubits. The realization of exceptional points in superconducting circuits is particularly appealing because quantum circuits are key candidates for the emerging quantum computing. In the present work, the exceptional points are realized using a superconducting resonator with a tunable frequency and damping rate, provided by a superconducting quantum interference device and a quantum-circuit refrigerator, respectively.

Chains of superconducting devices provide a natural platform for exploration of synthetic bosonic quantum matter, and the possibility to tune parametric disorder in situ makes them an ideal framework for the study of localization physics in particular. Here, the authors demonstrate that by tuning disorder strength via external magnetic field, one can probe both ergodic and many-body localized phases in a disordered bosonic Hubbard model. Simulations of time evolution suggest that coherence times of currently available devices are sufficiently long to distinguish between the two phases using the temporal fluctuations of local occupations.

Exceptional points enable the fastest possible dissipative energy transfer between quantum systems and, hence, are potentially required in optimal cooling of qubits. The realization of exceptional points in superconducting circuits is particularly appealing because quantum circuits are key candidates for the emerging quantum computing. In the present work, the exceptional points are realized using a superconducting resonator with a tunable frequency and damping rate, provided by a superconducting quantum interference device and a quantum-circuit refrigerator, respectively.
