Novel dynamical excitations and roton-based measurement of Cooper-pair momentum in a two-dimensional Fulde-Ferrell-Larkin-Ovchinnikov superfluid on optical lattices
Shuning Tan, Jiayi Shi, Peng Zou +2
Determining the center-of-mass (COM) momentum of Cooper pairs in unconventional superconductors or superfluids is a topic of great interest in condensed matter physics and ultracol…
Finding the stable mechanism of ring solitons in two-dimensional Fermi superfluids
Hao-Xuan Sun, Liu-Yang Cheng, Shi-Guo Peng +2
We theoretically investigate the stable mechanism of a ring soliton in two-dimensional Fermi superfluids by solving the Bogoliubov-de Gennes equations and their time-dependent coun…
A universal pairing gap measurement proposal by dynamical excitations in 2D doped attractive Fermi-Hubbard model with spin-orbit coupling
Huaisong Zhao, Rui Han, Ling Qin +2
By calculating dynamical structure factor of two-dimensional doped attractive Fermi-Hubbard model with Rashba spin-orbit coupling, we not only investigate collective modes and sing…
Dynamical excitations of one-dimensional Fulde-Ferrell pairing Fermi superfluid
Peng Zou, Huaisong Zhao, Feng Yuan +1
We theoretically investigate a one-dimensional Fulde-Ferrell Fermi superfluid at a finite effective Zeeman field , and study entire dynamical excitations related to density pert…
