This paper demonstrates the creation of Fermi-polaron polaritons in a gate-controlled transition-metal dichalcogenide photonic crystal, where the interplay of many-body interactions and light-matter coupling enables electrically invertible topological gaps and Chern numbers, overcoming the limitations of weak Zeeman splittings in semiconductor polariton systems.
This paper demonstrates that a back-gated multilayer WS transistor maintains strong gate tunability with an on/off ratio exceeding down to 20 mK, exhibiting reproducible shoulder-like turn-on features that are explained by a phenomenological model of multiple parallel conduction branches.
This paper theoretically demonstrates that a spatially varying temperature profile in ferromagnet/antiferromagnet bilayers induces chirality-selective magnon transport and generates a thermally triggered spin current in the antiferromagnet, offering new insights for designing magnonic heterostructures.
This study utilizes scanning near-field optical microscopy and low-temperature scanning tunneling microscopy to reveal atomic-scale lattice relaxation and topological flat bands in helical trilayer graphene, identifying a magic angle of approximately 1.9° and establishing a direct microscopic link between lattice structure and electronic properties.
By combining molecular dynamics simulations with theoretical modeling, this study demonstrates that ionic friction at solid-electrolyte interfaces arises primarily from collective many-body effects and solid fluctuations rather than individual drag forces, offering new spectral separation strategies for applications like desalination and energy conversion.
This paper presents a phase-field modeling strategy that incorporates CALPHAD-type thermodynamic descriptions of ordering in liquid solutions by defining internal variables and using Allen-Cahn relaxation equations, demonstrated through the formation of stoichiometric phases in Na-Sb and Na-Sn systems.
This study demonstrates that resonant photoluminescence in two-dimensional electron systems reveals the formation of incompressible quantum liquids starting at a filling factor of 1/3, characterized by disorder screening and an optical invariant sensitive to electron temperature, with a phase diagram showing smooth transitions between distinct quantum states as temperature decreases.
This study demonstrates that indirect excitons and their mediated spin transport in a MoSe/WSe van der Waals heterostructure exhibit long-range propagation of up to ~100 micrometers under magnetic fields up to 8 T, with decay distances that correlate between the two phenomena and vary non-monotonically with exciton density.
This study reveals that atomic-scale jogs in dislocations within face-centered cubic nickel break the symmetry of mechanical response by exhibiting significantly higher drag under reversed loading, a geometry-rooted mechanism driven by the coupling of non-affine atomic displacements and strain-like tensors that challenges classical plasticity models and offers new avenues for enhancing fatigue resistance.
This paper derives a multi-current kinetic uncertainty relation (MKUR) for classical stochastic systems and demonstrates that quantum-coherent evolution can violate this bound, thereby reducing joint current fluctuations below classical limits even in regimes where single-current bounds are satisfied.
