Non-adiabatic Ehrenfest dynamics with norm-conserving and ultra-soft pseudo-potentials with nuclear velocity corrections on the atomic orbitals within the Projector Augmented Wave Method framework

This paper derives a Galilean-invariant first-principles Ehrenfest molecular dynamics framework within the Projector-Augmented-Wave method that incorporates nuclear-velocity-dependent phases on atomic orbitals to eliminate spurious non-adiabatic couplings for both norm-conserving and ultra-soft pseudo-potentials.

Eigenmodes of synthetic antiferromagnetic skyrmions

This paper investigates the collective excitation modes of confined synthetic antiferromagnetic skyrmions using micromagnetic simulations, revealing how antiferromagnetic interlayer coupling and geometric confinement transform low-frequency dynamics from gyrotropic and breathing modes into distinct translational and out-of-phase breathing oscillations, including signal propagation in skyrmion chains.

1/3 Fractional and Gapless Integer Quantum Anomalous Hall States in Rhombohedral Graphene

This study reports the first observation of the fundamental 1/3 fractional quantum anomalous Hall state and a gapless extended quantum anomalous Hall phase in rhombohedral pentagonal graphene/hBN moiré superlattices, revealing a particle-hole symmetric phase diagram and enabling thermodynamic characterization of topological transitions at zero magnetic field.

Enhancement of charge correlations and real-space topological marker on an interacting non-Hermitian Su-Schrieffer-Heeger model

This paper investigates the interacting non-Hermitian Su-Schrieffer-Heeger model to demonstrate that a real-space topological marker robustly identifies topological phases and their breakdown into charge density waves, while revealing that non-Hermiticity significantly amplifies interaction-induced charge correlations, particularly near exceptional points under open boundary conditions.

Electrically tunable MoSe2_2/WSe2_2 heterostructure-based quantum dot

This paper presents a theoretical study demonstrating that vertical electric fields can electrically tune the valley character and occupancy of states in MoSe2_2/WSe2_2 heterostructure-based quantum dots, enabling selective localization of electrons in either the KK or QQ valleys through a combination of density functional theory and an \textit{ab initio}-based tight-binding model.
