Strain-controlled crossover between Majorana and Andreev bound states in disordered superconductor-semiconductor heterostructures

This paper demonstrates that spatially nonuniform strain serves as a systematic tuning parameter to control the crossover between trivial partially separated Andreev bound states and topological Majorana bound states in disordered superconductor-semiconductor heterostructures, thereby offering a robust experimental pathway for distinguishing and stabilizing Majorana modes for quantum computation.

Valley-Controlled Viscosity of Two-Dimensional Dirac Fluids

Motivated by recent experiments in twisted bilayer graphene, this paper demonstrates that valley imbalance serves as a tunable knob to control the viscosity of two-dimensional Dirac fluids, inducing a pronounced nonmonotonic response through distinct transport regimes while contrasting this behavior with the monotonically decreasing kinematic viscosity of monolayer graphene.

Laser-assisted tunneling in a static tungsten diselenide WSe $_2$ barrier

This study demonstrates that irradiating a static tungsten diselenide (WSe $_2$ ) barrier with a linearly polarized laser field induces rich Floquet sideband structures and Stark-like confined states, which effectively suppress Klein tunneling and enable dynamic control of quantum transport for potential optoelectronic applications.

Topological edge states of the hexagonal linear chain

This paper investigates a one-dimensional hexagonal molecular chain with alternating hopping parameters, identifying two insulating phases separated by a gap-closing transition and demonstrating the emergence of exponentially localized topological edge states in the phase where the hopping ratio is below a critical value.

Mechanical detection of sub-band mobilities of two-dimensional electron gas on reduced SrTiO $_3$ (001) surface

This study establishes a non-invasive atomic force microscopy methodology to detect and quantify sub-band carrier mobilities in the two-dimensional electron gas of reduced SrTiO $_3$ (001) by analyzing bias-dependent dissipation peaks linked to quantum capacitance variations and Kohler's rule under magnetic fields.

Ordering governs magnetic tunability in FePt-based Janus particles independent of curvature

This study demonstrates that the magnetic tunability of micrometer-scale FePt-based Janus particles is governed primarily by chemical ordering rather than particle curvature, as evidenced by experiments and simulations showing that coercivity remains constant across varying diameters while being strongly dependent on L1_0 ordering.

Local temperature control of magnon frequency and direction of supercurrents in a magnon Bose-Einstein condensate

This study demonstrates that local laser heating in magnetic films induces both magnetization and demagnetizing field variations, which collectively create a local magnon frequency minimum that drives the formation of a magnon supercurrent directed away from the heated region.
