Recent experiments [Science 357, 294 (2017)] have observed a half-quantized electrical conductance plateau, a proposed signature of chiral Majorana fermions. Such Majoranas have been argued to occur generically when a quantum anomalous Hall insulator is tuned to its plateau transition and proximitized by a superconductor. The authors show here that such half-quantized conductance can also occur in this system even in the absence of chiral Majorana fermions, once experimental disorder and temperature are considered. This work therefore motivates the search for more compelling evidence of chiral Majorana fermions in this system, such as quantum coherent interferometry or half-quantized thermal conductance.

Helium bubbles can form in a wide variety of materials and are of significance in a great variety of circumstances, ranging from electronics through nuclear physics or geology to outer-space exploration. However, their properties remain elusive, especially at the nanometer scale. Here, the authors study by means of transmission electron microscopy the structural modification and, simultaneously, the helium emission from individual nanosized bubbles in silicon during annealing. It is shown that, surprisingly, helium emission takes place at temperatures where bubble migration has barely begun. Analytical modeling of helium emission suggests that helium is in its solid state in the most highly pressurized bubbles.

Friction between sliding objects is a phenomenon so ubiquitous that it is easily forgotten how few of its microscopic details are properly understood. To gain new insight into the dynamical mechanism of sliding dissipation, the authors investigate a minimal model of a rigid slider traveling over a harmonic substrate. With the analytical tools of linear response theory, the authors obtain an expression for the dynamical friction that depends on known static physical quantities. This result sheds new light on the physical intertwining between dissipation and the phononic degrees of freedom of the substrate.

The freezing temperature of solid hydrogen may be significantly lowered below its bulk value by encapsulating the sample in a restricted geometry. The authors report on an electron-spin resonance (ESR) study of H atoms, stabilized in highly porous solid mixtures of neon and molecular hydrogen at temperatures below 1 K. The ESR analysis shows that H atoms stabilize into two different substitutional sites of the Ne lattice and into H clusters, formed in solid neon. The hydrogen atoms in H clusters rapidly recombine upon raising the temperature from 0.1 to 0.3–0.6 K, which is attributed to a solid-liquid transition in the H clusters formed in solid Ne.

Periodic photonic structures such as metamaterials, plasmonic lattices, and excitons strongly coupled to photonic crystals are governed by non-Hermitian wave operators with explicitly energy-dependent potentials. The resulting eigenstates no longer form a basis of the vector space of physical states, nor are they normalizable via the common scalar product. This poses particular problems for the calculation of Green functions and densities of states. Here, the authors solve this challenge via the adjoint operator and modes for arbitrary dispersive and lossy periodic systems. This work can be readily adapted to nonoptical complex band-structure problems with energy-dependent potentials, e.g., within solid-state theory.

Disorder and interactions can lead to the breakdown of statistical mechanics in quantum systems by transitioning to a many-body localized (MBL) phase. The thermal-to-MBL transition occurs by either increasing the amount of disorder present in a system or by decreasing its energy until it crosses the so-called mobility edge. The authors construct a set of approximate integrals of motion that are quasi-universal across the energy spectrum and, thus, across the mobility edge, too. Interestingly, MBL eigenstates under the mobility edge are aware of the existence of a thermal phase at a higher energy. The phase diagram is probed close to the transition and in the MBL phase. One finds a universal distribution of the strength of the couplings of the integrals of motion in the strong disorder limit.
