This paper demonstrates that coupling magnons to lattice vibrations via Dzyaloshinskii-Moriya interaction fluctuations in a two-dimensional ferromagnetic skyrmion crystal reconstructs the low-energy spectrum to generate topological magnon-phonon hybrid bands with nontrivial Chern numbers and robust edge states, even when the underlying bare magnon bands are topologically trivial.
This paper formulates a class C quantum network model with random tunneling to investigate the spin quantum Hall effect, deriving its large- nonlinear sigma model representation and revealing how triplet mode coupling, tunneling asymmetry, and Zeeman fields influence the theory's effective behavior and symmetries.
This paper investigates the interplay of disorder and interactions in two-dimensional quantum Hall systems, revealing a disorder-driven phase transition sequence from incompressible fractional quantum Hall liquids to locally ordered solids and finally to amorphous states, a progression that qualitatively aligns with recent scanning tunneling microscopy experimental observations.
This study employs first-principles calculations and tight-binding models to investigate the magnetization-induced gap, sidewall states, and half-quantized anomalous Hall conductance in three specific ferromagnet/topological insulator van der Waals heterostructures, while also analyzing the factors that may hinder exact half-quantization in realistic systems.
This study demonstrates that introducing chalcogen cluster vacancies into trigonal () monolayers induces a structural reconstruction into an inverse Lieb lattice, which realizes two-dimensional d-wave altermagnetism characterized by momentum-dependent spin splitting and zero net magnetization.
This paper demonstrates that incorporating multi-spin biquadratic exchange into helimagnetic models creates a "Simplicial Bridge" to generalized Kuramoto networks, revealing that higher-order triadic couplings induce explosive synchronization transitions and macroscopic magnetic chimera states in honeycomb lattices.
This paper demonstrates that a coplanar kagome antiferromagnet can generate unconventional alternating out-of-plane spin polarization and spin-polarized transport through magnetic chirality and spatial confinement, achieving these effects without relying on relativistic spin-orbit coupling.
This study utilizes Kelvin Probe Force Microscopy to map the stacking-dependent work function and local photoresponse of CVD-grown MoS2 bilayers, revealing how interlayer coupling, substrate-induced photogating, and surface particulate trapping collectively govern their nanoscale optoelectronic behavior.
This paper demonstrates that sample-and-hold multiplexed cryo-CMOS control can reliably bias and pulse an isolated silicon double quantum dot at 0.5K, confirming its compatibility with the stability and speed requirements necessary for scalable spin-qubit processors.
This study reports the crystal structure of a new helical InSeI polymorph and utilizes polarized Raman spectroscopy to map its lattice dynamics and chain orientation, revealing that despite its helical structure, the material lacks chiral phonons.
