Spin-Orbit Coupling-Driven Chirality Switching of Spin Waves in Altermagnets
Wen-Tong Li, Yu-Biao Wu, Lin Zhuang +2
Altermagnets host intrinsically chirality-splitting spin waves, which offer an ideal platform for chirality-based computing with low energy consumption and fast dynamics. However,…
Chiral symmetry breaking in the pseudo-quantum electrodynamics with non-Abelian four-fermion interactions
Qiao Yang, Yu-Biao Wu, Wu-Ming Liu
In the context of 2+1 dimensional Dirac materials, we consider electromagnetic interactions alongside a type of spin-dependent Hubbard interaction. The former is described by PQED…
Strongly-tilted field induced Hamiltonian dimerization and nested quantum scars in the 1D spinless Fermi-Hubbard model
Wei-Jie Huang, Yu-Biao Wu, Guang-Can Guo +2
We investigate the quantum dynamics of the 1D spinless Fermi-Hubbard model with a linear-tilted potential. Surprisingly in a strong resonance regime, we show that the model can be…
Visualization of Skyrmion-Superconducting Vortex Pairs in a Chiral-Magnet-Superconductor Heterostructure
Yong-Jie Xie, Ang Qian, Bin He +6
Magnetic skyrmions, the topological states possessing chiral magnetic structure with nontrivial topology, have been widely investigated as a promising candidate for spintronic devi…
Non-Hermitian superfluid--Mott-insulator transition in the one-dimensional zigzag bosonic chains
Chengxi Li, Yubiao Wu, Wu-Ming Liu
We investigated the behavior of non-Hermitian bosonic gases with Hubbard interactions in the one-dimensional zigzag optical lattices through the calculation of dynamic response fun…
