Quantum critical properties of non-Hermitian XY models with magnetic field
Jia-Jia Luo, Volker Meden
The characterization of the quantum critical properties of genuine non-Hermitian many-body systems remains ambiguous as neither the state considered nor the definition of expectati…
Quantum transport in 1D Hubbard model: Drude weights and Seebeck effect
Jia-Jia Luo, Sagarika Basak, Han Pu +1
The Drude weight (DW) is an essential quantity that characterizes the quantum transport properties of many-body systems. However, a rigorous understanding and exact computation of…
Haldane Fractional Statistics for 1D Heisenberg Spin XXX Chain
Wei-Jia Liu, Jia-Jia Luo, Xi-Wen Guan
Haldane's fractional exclusion statistics (FES) describes a generalized Pauli exclusion statistics, which can be regarded as an emergent quantum statistics induced by the intrinsic…
Exact results of one-dimensional repulsive Hubbard model
Jia-Jia Luo, Han Pu, Xi-Wen Guan
We present analytical results of fundamental properties of one-dimensional (1D) Hubbard model with a repulsive interaction, ranging from fractional excitations to universal thermod…
