A team of experimentalists and theorists proposes a scalable protocol for quantum computation based on topological superconductors.

Single-particle excitations in disordered Weyl fluids

J. H. Pixley, Yang-Zhi Chou, Pallab Goswami, David A. Huse, Rahul Nandkishore, Leo Radzihovsky, and S. Das Sarma

Phys. Rev. B 95, 235101 (2017) - Published 1 June, 2017

The authors determine the fate of single-particle Weyl excitations in the presence of short-range disorder. Using analytic and numerical methods, the authors show that weakly disordered Weyl excitations are not ballistic and acquire an exponentially small but nonzero quasiparticle lifetime due to rare regions of the random disorder potential. As a result, the Green function near the Weyl quasiparticle peaks remains analytic and the avoided quantum critical point renormalizes the single-particle excitation spectrum at finite momentum.

Entanglement phases as holographic duals of anyon condensates

Kasper Duivenvoorden, Mohsin Iqbal, Jutho Haegeman, Frank Verstraete, and Norbert Schuch

Phys. Rev. B 95, 235119 (2017) - Published 12 June, 2017

Topological phases are exotic states of matters which do not order locally yet exhibit a global ordering in their entanglement, making their characterization a challenging task. In this work, the authors construct an explicit holographic duality between topological phases in the bulk and the structure of the entanglement spectrum at its boundary, thereby establishing a one-to-one correspondence between different bulk topological orders and symmetry-breaking and symmetry-protected orderings of the entanglement. This allows classification and detection of topological phases holographically through “entanglement spectroscopy” at the boundary, and construction of order parameters that measure the condensation and confinement of anyons, and thus permits characterization of the nature of topological phase transitions.

Parafermionic clock models and quantum resonance

N. Moran, D. Pellegrino, J. K. Slingerland, and G. Kells

Phys. Rev. B 95, 235127 (2017) - Published 15 June, 2017

Resonance effects lead to surprising and beautiful phenomena in many areas of physics. Here, the authors identify resonance points as key to understanding the breakdown and revival of strong zero modes in parafermionic clock models. Through analytic and numerical methods, they have been able to determine the behavior at and away from resonance points, proving many statements about the asymptotic behavior of these systems. In particular, they show that there exists special points in parameter space where strong zero modes can exist and, as such, topological degeneracy is preserved at all energies.

Classification of (2+1)-dimensional topological order and symmetry-protected topological order for bosonic and fermionic systems with on-site symmetries

Tian Lan, Liang Kong, and Xiao-Gang Wen

Phys. Rev. B 95, 235140 (2017) - Published 22 June, 2017

Large classes of matter have been systematized before by using a pair of groups to classify all spontaneous symmetry breaking phases or by using a pair of groups plus projective representations to classify all gapped quantum phases of one-dimensional boson and fermion systems with various symmetries. In this paper, the authors go beyond this and use a pair of groups plus three braided fusion categories and a chiral central charge in order to classify gapped quantum phases of two-dimensional boson and fermion systems with various finite symmetries. This allows, among other things, to generate many group tables of two-dimensional gapped phases.

Poor electronic screening in lightly doped Mott insulators observed with scanning tunneling microscopy

I. Battisti, V. Fedoseev, K. M. Bastiaans, A. de la Torre, R. S. Perry, F. Baumberger, and M. P. Allan

Phys. Rev. B 95, 235141 (2017) - Published 23 June, 2017

The interpretation of scanning tunneling microscopy (STM) data on poorly metallic materials is challenging: one needs to take into account the partial penetration of the electric field into the sample, the so-called tip-induced band bending (TIBB). This effect is well known from STM experiments on semiconductors, but rarely discussed for correlated-electron systems. The authors find that in the lightly doped Mott insulator (Sr1-xLax)2IrO4, TIBB is at the root of apparent discrepancies in the gap values measured by photoemission, optical measurements, and STM. They develop a model to extract the intrinsic Mott gap of the system, leading to agreement with results from other techniques.

Low-energy magnon dynamics and magneto-optics of the skyrmionic Mott insulator Cu2OSeO3

Phys. Rev. B 95, 235155 (2017) - Published 29 June, 2017

The Dzyaloshinskii-Moriya interaction is vital in stabilizing the magnetic phases of chiral magnets, but how does this interaction manifest itself in the magnetic excitation spectrum? The authors perform high resolution time-domain terahertz spectroscopy experiments and time-of-flight neutron scattering experiments to investigate the low-energy magnetic response of the newly discovered insulating and magnetoelectric chiral magnet Cu2OSeO3. Transmission and polarimetry experiments performed as a function of magnetic field uncover new magnetic excitations, detect the topologically nontrivial skyrmion phase, and reveal unexpected magnon dynamics. These observations are consistent with the presence of an exceptionally strong Dzyaloshinskii-Moriya interaction in this material and highlight the need for its inclusion if the magnetic response of such chiral magnets is to be completely understood..

Magnetism and charge density waves in RNiC2(R=Ce,Pr,Nd)

Kamil K. Kolincio, Marta Roman, Michał J. Winiarski, Judyta Strychalska-Nowak, and Tomasz Klimczuk

Phys. Rev. B 95, 235156 (2017) - Published 29 June, 2017

In this article, the authors investigate the interplay between the Peierls instability and magnetism in members of the RNiC2 family, where R=Nd, Pr, Ce. Transport, magnetic, specific heat, and galvanomagnetic properties are studied. In NdNiC2, the charge density wave state is partially suppressed by an antiferromagnetic transition. The application of a strong enough magnetic field induces a ferromagnetic transition, accompanied by further destruction of the charge density wave and by a metastable lattice transformation. PrNiC2 shows the opposite behavior in that, although the Peierls instability is initially weakened by the Zeeman splitting of the conduction bands, the magnetic anomaly restores and even enhances the nesting conditions.

Microwave irradiation and quasiparticles in a superconducting double dot

N. J. Lambert, A. A. Esmail, F. A. Pollock, M. Edwards, B. W. Lovett, and A. J. Ferguson

Phys. Rev. B 95, 235413 (2017) - Published 9 June, 2017

The detection of single microwave photons remains a difficult challenge because of their low energy. The authors demonstrate that an aluminum superconducting double dot can be tuned to a regime in which a photon creating a single quasiparticle pair changes the quantum capacitance of the device. By using high-bandwidth reflectometry techniques, they observe the absorption of photons in real time. They also exploit the band structure of the device to tune the frequencies to which it is sensitive and use this to carry out spectroscopy on the ambient black-body radiation environment in their dilution refrigerator.

Topological crystalline materials: General formulation, module structure, and wallpaper groups

Ken Shiozaki, Masatoshi Sato, and Kiyonori Gomi

Phys. Rev. B 95, 235425 (2017) - Published 19 June, 2017

Topological crystalline materials are emergent topological phases due to crystalline space group symmetry. They are either gapful or gapless in the bulk, while hosting topological states at the boundary. Here, the authors define topological crystalline materials rigorously on the basis of a mathematical theory, known as twisted equivariant K-theory. Abstract mathematical ideas, such as the Mayer-Vietoris sequence and module structure, are explained in terms of band theory. The formulation is applicable to bulk gapful topological crystalline insulators/superconductors and their gapless boundary and defect states as well as to bulk gapless topological materials, such as Weyl and Dirac semimetals or nodal superconductors. The authors present a complete classification of topological crystalline surface states and band insulators protected by 17 wallpaper groups in the absence of time-reversal invariance, which may support topological states beyond simple Dirac fermions.

The detection of single microwave photons remains a difficult challenge because of their low energy. The authors demonstrate that an aluminum superconducting double dot can be tuned to a regime in which a photon creating a single quasiparticle pair changes the quantum capacitance of the device. By using high-bandwidth reflectometry techniques, they observe the absorption of photons in real time. They also exploit the band structure of the device to tune the frequencies to which it is sensitive and use this to carry out spectroscopy on the ambient black-body radiation environment in their dilution refrigerator.

Topological crystalline materials are emergent topological phases due to crystalline space group symmetry. They are either gapful or gapless in the bulk, while hosting topological states at the boundary. Here, the authors define topological crystalline materials rigorously on the basis of a mathematical theory, known as twisted equivariant K-theory. Abstract mathematical ideas, such as the Mayer-Vietoris sequence and module structure, are explained in terms of band theory. The formulation is applicable to bulk gapful topological crystalline insulators/superconductors and their gapless boundary and defect states as well as to bulk gapless topological materials, such as Weyl and Dirac semimetals or nodal superconductors. The authors present a complete classification of topological crystalline surface states and band insulators protected by 17 wallpaper groups in the absence of time-reversal invariance, which may support topological states beyond simple Dirac fermions.
