EDITORS' SUGGESTION

Anderson localization transitions with and without random potentials

Trithep Devakul and David A. Huse

Phys. Rev. B 96, 214201 (2017) - Published 6 December, 2017

Anderson localization of noninteracting particles has traditionally been viewed as being due to random potentials. However, random potentials are not needed, and localization due to nonrandom quasiperiodic potentials is well studied in one dimension. The authors extend this work to higher dimensions. A quantum particle in a quasiperiodic potential in three dimensions has three “eigenstate phases”: a localized phase at strong potential, a ballistic phase at weak potential, and a diffusive phase in between. They find that the universality class of the Anderson localization transitions in three dimensions is insensitive to whether or not the potential is random, which is not true in fewer dimensions.

Multifractality of wave functions on a Cayley tree: From root to leaves

M. Sonner, K. S. Tikhonov, and A. D. Mirlin

Phys. Rev. B 96, 214204 (2017) - Published 20 December, 2017

Disordered quantum systems undergo Anderson localization-delocalization transitions, which exhibit very rich physics. A remarkable feature of these transitions is the multifractality of critical wave functions. The eigenfunction multifractality in a $d$ -dimensional disordered system holds only at the transition point and is characterized by universal critical exponents. The authors explore the evolution of wave-function statistics on a finite Bethe lattice from the central site (“root”) to the boundary (“leaves”). They show that eigenfunction moments exhibit generally a multifractal scaling with the volume $N$ . The multifractality spectrum $τ_{q}$ depends on the disorder strength and on the parameter $s$ characterizing the position of the observation point, $s$ = $r / R$ , where $r$ is the distance to the root and $R$ is the “radius” of the lattice.

Multifractal metal in a disordered Josephson junctions array

M. Pino, V. E. Kravtsov, B. L. Altshuler, and L. B. Ioffe

Phys. Rev. B 96, 214205 (2017) - Published 20 December, 2017

Superconducting circuits provide a very attractive platform to study the transition from chaotic ergodic to full localized behavior expected in closed quantum systems. The present work reports the emergence of a chaotic, yet nonergodic regime that preempts the transition into a fully localized state in Josephson junction chains. The lack of ergodicity is reflected in multifractal eigenstates in the many-body space. Furthermore, the multifractality in the phase space is accompanied by the fractal properties of the local energy spectrum that translates into anomalous power-law behavior of the physical correlators. The observation of a fractal structure in the local energy spectrum of Josephson junction arrays may provide a bridge between nonergodic dynamics of quantum systems and the hierarchical structure of the local minima in the theory of classical spin glasses.

EDITORS' SUGGESTION

No evidence for orbital loop currents in charge-ordered ${YBa}_{2} {Cu}_{3} O_{6 + x}$ from polarized neutron diffraction

T. P. Croft, E. Blackburn, J. Kulda, Ruixing Liang, D. A. Bonn, W. N. Hardy, and S. M. Hayden

Phys. Rev. B 96, 214504 (2017) - Published 15 December, 2017

An ubiquitous feature of cuprate superconductors is the existence of a normal-state pseudogap for underdoped compositions. Several experiments suggest that there may be a phase transition to the pseudogap state in which a symmetry is broken. One proposed scenario is that the pseudogap state breaks time-reversal symmetry due to the formation of circulating currents within each unit cell. The authors study underdoped YBa $_{2}$ Cu $_{3}$ O $_{6 + x}$ using polarized neutron scattering and show that this scenario is unlikely.

EDITORS' SUGGESTION

Superconductivity in three-dimensional spin-orbit coupled semimetals

Lucile Savary, Jonathan Ruhman, Jörn W. F. Venderbos, Liang Fu, and Patrick A. Lee

Phys. Rev. B 96, 214514 (2017) - Published 28 December, 2017

The discovery of superconductivity in the $j$ = $\frac{3}{2}$ spin-orbit coupled half-Heusler semimetals has given the field of low-density superconductivity a new twist. Exotic pairings are likely, yet the favored superconducting instabilities remain to be determined. The authors provide a method to analyze superconductivity in systems with symmetry-protected band touchings. They apply it to $j$ = $\frac{3}{2}$ systems to find that polar phonons play an important role in the superconducting mechanism of the half-Heusler compounds. They also explicitly show a number of new features associated with such band structures, such as the strong dependence on hole or electron doping in the determination of the leading odd-parity superconducting instability.

EDITORS' SUGGESTION

Phase-driven collapse of the Cooper condensate in a nanosized superconductor

Alberto Ronzani, Sophie D'Ambrosio, Pauli Virtanen, Francesco Giazotto, and Carles Altimiras

Phys. Rev. B 96, 214517 (2017) - Published 29 December, 2017

The phase degree of freedom is a core property of the superconducting state, intimately linked to its coherent yet macroscopic nature. The authors directly observe evidence of a complete suppression of the superconducting energy gap in a nanosized aluminum wire upon subjecting the latter to an appropriate phase gradient by means of a micro-interferometer. They exploit the sharp magnetic response obtained with the design to realize ultrasensitive magnetic flux detectors.
