We demonstrate that structural chirality provides a robust and intrinsic mechanism for controlling Majorana zero modes (MZMs) in chiral nanowires coupled to $s$-wave superconductors. In a tight-binding model of helical nanowires, nanowires with opposite chirality share identical bulk spectra and topol…

The persistence of ferroelectricity in ultrathin ${\mathrm{HfO}}_2$ films challenges conventional theories, particularly given the paradoxical observation that the out-of-plane lattice spacing increases as the film thickness decreases, an anomalous size effect absent in perovskite ferroelectrics. Here, we resolve…

Real surfaces are rough on many length scales, but flash-temperature theories have traditionally assumed single-scale contacts. Müser and Persson derive here an analytical multiscale theory of frictional heating and verify it against numerical simulations. They show that the classical models can fail dramatically for realistic rough surfaces. The work provides a quantitative framework for predicting thermal hotspots in systems ranging from rubber friction to earthquake faults.

The authors introduce here a new mechanism that produces a Hall-like transverse response in time-reversal-invariant materials, driven entirely by geometric effects. A tilted potential interface causes electron wave packets to undergo a refractionlike deflection upon transmission, generating a finite transverse current and Hall-like conductance without magnetic fields or broken time-reversal symmetry. The analytical framework and numerical simulations across multiple lattice models and device geometries establish the conductance signatures, while real-time wave-packet dynamics confirms the geometric origin and robustness of this effect.

Most moiré superlattices studied to date are two-dimensional, but a recently discovered one-dimensional counterpart raises the question of whether it can host genuinely one-dimensional electronic states. Here, the authors show that lattice relaxation in twisted bilayer WTe${}_2$ generates nearly one-dimensional electronic bands and reveal the microscopic origin of this behavior. They also develop a general theoretical framework for understanding and predicting one-dimensional moiré superlattices in a broad class of anisotropic layered materials.
