Flat-band Ferromagnetism of SU Hubbard Model on the Kagome Lattices
Hao Jin, Wenxing Nie
The kagome lattice, a well known example of the geometrically frustrated system, hosts a dispersionless flat band that offers a unique platform for studying correlation-driven quan…
Non-Hermitian Chiral Superfluids with a Complex Interaction
Jia-Hang Ji, Wenxing Nie
Recently, the influence of dissipation on a quantum system has attracted much attention, particularly on how the non-Hermitian terms modify the energy spectrum, band topology, and…
Vortices in Two-Dimensional Chiral Superfluids
Yan He, Wenxing Nie
We study the orbital angular momentum (OAM) of two-dimensional chiral -wave superfluids (SFs) in the presence of an axisymmetric multiply quantized vortex (MQV)…
Edge current and orbital angular momentum of chiral superfluids revisited
Wenxing Nie, Wen Huang, Hong Yao
Cooper pairs in chiral superfluids carry quantized units of relative orbital angular momentum (OAM). Various predictions of the intrinsic OAM density or the macroscopic OAM of a tw…
Flat-band Ferromagnetism of the SU Hubbard Model on the Tasaki Lattice
Rui-Jin Liu, Wenxing Nie, Wei Zhang
We investigate the para-ferro transition of the repulsive SU() Hubbard model on one- and two-dimensional Tasaki lattices. Under certain restrictions for constructing localized m…
Weyl magnons in pyrochlore antiferromagnets with all-in-all-out orders
Shao-Kai Jian, Wenxing Nie
We investigate novel topological magnon band crossings of pyrochlore antiferromagnets with all-in-all-out (AIAO) magnetic order. By general symmetry analysis and spin-wave theory,…
Ferromagnetic ground state of SU(3) Hubbard model on the Lieb lattice
Wenxing Nie, Deping Zhang, Wei Zhang
We investigate the magnetic properties of a repulsive fermionic SU() Hubbard model on the Lieb lattice from weak to strong interaction by means of the mean-field approximation.…
Orbital Angular Momentum and Spectral Flow in Two Dimensional Chiral Superfluids
Yasuhiro Tada, Wenxing Nie, Masaki Oshikawa
We study the orbital angular momentum (OAM) in two dimensional chiral -wave superfluids (SF) of fermions on a disc at zero temperature, in terms of spectral…
Particle Statistics, Frustration, and Ground-State Energy
Wenxing Nie, Hosho Katsura, Masaki Oshikawa
We study the connections among particle statistics, frustration, and ground-state energy in quantum many-particle systems. In the absence of interaction, the influence of particle…
Ground-state Energies of Spinless Free Fermions and Hard-core Bosons
Wenxing Nie, Hosho Katsura, Masaki Oshikawa
We compare the groundstate energies of bosons and fermions with the same form of the Hamiltonian. If both are noninteracting, the groundstate energy of bosons is always lower, owin…
