Field-amplified readouts of weak altermagnetic exchange in MnF
Guowen Jiang, Feilong Wang, Yunhua Wang +4
MnF, the textbook two-sublattice antiferromagnet, has reemerged as a prototypical altermagnet, yet the sublattice-odd exchange that defines this identity remains under active d…
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
Quenched disorder can disrupt crystalline order without immediately destroying the topology of its constituent textures, but the relation between these processes in skyrmion crysta…
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…
Energy Dispersion, Superconductivity and Magnetic Fluctuations in Stacked Altermagnetism Materials
Jun Chang, Hantao Lu, Jize Zhao +2
Recently, altermagnetism (AM) has emerged as a new category of magnetism, alongside conventional antiferromagnetism (AFM) and ferromagnetism (FM). In an AM, superconductivity (SC)…
Altermagnetism and beyond in the -- Fermi-Hubbard model
Saisai He, Jize Zhao, Hong-Gang Luo +1
In this work, we revisit the phase diagram of the -- Fermi-Hubbard model on the square lattice to gain a more comprehensive understanding of this correlated model a…
Emergent supercounterfluid and quantum phase diagram of two-component interacting bosons in one-dimensional optical lattice
Saisai He, Yang Liu, Bin Xi +3
Motivated by a recent experiment that realizes nearest-neighbor dipolar couplings in an optical lattice [C. Lagoin, , Nature , 485 (2022)], we study…
Weak electronic correlations in the cobalt oxychalcogenide superconductor Na2CoSe2O
Zhenchao Wu, Yingying Cao, Hong-Gang Luo +1
Motivated by the newly discovered Co-based superconductor Na2CoSe2O, we performed systematic calculations of its electronic band structures using the density functional theory (DFT…
Quantum dynamics in a spin-1/2 square lattice -- altermagnet
Yang Liu, Shiqi Shao, Saisai He +4
A key feature of the newly discovered altermagnet is that its spin degeneracy is lifted, although it has an antiferromagnetic order and zero net magnetization. In this work, we inv…
Identifying the ground state phases by spin-patterns in the Shastry-Sutherland model
Yun-Tong Yang, Fu-Zhou Chen, Hong-Gang Luo
Exploring the influence of frustration on the phases and related phase transitions in condensed matter physics is of fundamental importance in uncovering the role played by frustra…
