Generalized Effective Spin-Chain formalism for multicomponent anyons in one-dimensional optical lattices
Sagarika Basak, Xi-Wen Guan, Han Pu
We develop a generalized effective spin-chain (GESC) formalism for strongly interacting multicomponent anyons in a one-dimensional (1D) optical lattice. By mapping particle motion…
Multicomponent anyons in one-dimensional optical lattices
Sagarika Basak, Xi-Wen Guan, Han Pu
We investigate the ground-state and dynamical properties of multicomponent interacting anyons confined in a one-dimensional (1D) optical lattice. Adopting the Anyon--Hubbard model,…
Tomonaga-Luttinger liquid theory for one-dimensional attractive Fermi gases
Hai-Ying Cui, Yu-Hao Yeh, Randall G. Hulet +3
The one-dimensional (1D) Yang-Gaudin model--an integrable -function interacting Fermi gas, serves as a paradigm in quantum many-body physics, encompassing phenomena from spin-ch…
Low Energy Excitations of a 1D Fermi Gas with Attractive Interactions
Aashish Kafle, Ruwan Senaratne, Danyel Cavazos-Cavazos +5
The low-energy excitations of a two-component repulsive Fermi gas confined to one dimension are linear dispersing spin- and charge-density waves whose respective propagation veloci…
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…
