In-plane magnetic response and Maki parameter of alternating-twist multilayers

This paper analytically demonstrates that alternating-twist multilayer graphene systems exhibit a unique hierarchy of magic angles and distinct in-plane orbital magnetic responses—negligible for odd-layer systems but highly angle-dependent and significantly enhanced for even-layer systems—leading to large in-plane Maki parameters that suggest the potential for diverse superconducting phases.

Direct observation of ultrafast defect-bound and free exciton dynamics in defect-engineered WS2_2 monolayers

This study utilizes ultrafast optical spectroscopy to directly observe and characterize the sub-picosecond formation, trapping, and coherent interconversion dynamics between free and defect-bound excitons in alkali metal halide-assisted CVD-grown monolayer WS2_2 with high defect densities.

Topological superconductivity of a two-dimensional electron gas at the (001) LaAlO\textsubscript{3}/SrTiO\textsubscript{3} interface

This paper investigates topological superconductivity and Majorana zero modes in the LaAlO3_3/SrTiO3_3 interface using a realistic multiband model, revealing that while a finite out-of-plane magnetic field is required for the topological transition in 2D systems, lateral confinement relaxes this constraint but introduces challenges for observing Majorana states in nanowires due to the exceptionally long localization lengths of dyz/xzd_{yz/xz} orbital-dominated subbands.

Extended saddle points govern long-lived antiskyrmions

This paper demonstrates that anisotropic Dzyaloshinskii-Moriya interaction in oxidized Fe3_3GeTe2_2 stabilizes long-lived antiskyrmions by creating spatially extended saddle points that suppress entropic contributions to decay, thereby rendering soliton lifetimes effectively temperature-independent and enhancing stability by over five orders of magnitude at room temperature.

Geometric blockade in a quantum dot coupled to two-dimensional and three dimensional electron gases

The authors report the observation of a bias-dependent "geometric" current blockade in a quantum dot coupled to 2D and 3D electron gases, where asymmetric tunneling induces a population inversion into a metastable dark triplet state that suppresses current transport due to the geometric shape of the electronic eigenstates.
