Spin Splitter without Spin-Split Bands: A Reconfigurable Altermagnetic Texture
Bin Xi, Jie Lu, Qiang Luo +4
The altermagnetic spin-splitter effect converts an electric field into a transverse pure spin current, with no net magnetization and no charge-Hall counterpart. In established mate…
Ground-state phase diagram and route to supersolidity in a two-component extended Bose-Hubbard model
Xuexin Qiu, Ning Bian, Yang Liu +4
We investigate the ground-state phase diagram of a two-component extended Bose-Hubbard model recently realized with dipolar excitons, using the projected entangled-pair states. For…
Generalized Holstein-Primakoff transformation with optimizable bosonic truncation
Yang Liu, Jia-Wei Mei, Rong Yu +3
Spin-wave theory provides a quasiparticle description of excitation spectra in quantum spin systems. In this theory, the spin operators are usually bosonized by the Holstein-Primak…
Field-Selected Topological Buffering in a Disordered Skyrmion Crystal
Wenyu Su, Nvsen Ma, Chen Cheng +1
The paper uses large‑scale simulations to show that a magnetic field can separate the loss of crystalline order from the loss of topological charge in disordered skyrmion crystals,…
Beyond-adiabatic flat Chern bands from a double-helix skyrmion crystal
Bin Xi, Ken Chen, Qiang Luo +4
A central challenge in flat-band engineering is suppressing kinetic energy without sacrificing Berry curvature. We show that a double-helix skyrmion crystal (DHSKX)--two sublattice…
On the Origin of the Hidden Symmetry in the Asymmetric Quantum Rabi Model
Yun-Tong Yang, Song-Ming Chen, Hong-Gang Luo
The introduction of an asymmetric term into the quantum Rabi model generally lifts energy-level degeneracies. However, when the asymmetry parameter takes specific multiples of the…
