Microscopic origin of quantum supersonic phenomenon in one dimension
Zhe-Hao Zhang, Yuzhu Jiang, Hai-Qing Lin +1
Using the Bethe ansatz (BA), we rigorously obtain non-equilibrium dynamics of an impurity with a large initial momentum in the one-dimensional (1D) interacting bosonic medium.…

Emergence and disruption of spin-charge separation in one-dimensional repulsive fermions
Feng He, Yu-Zhu Jiang, Hai-Qing Lin +3
At low temperature, collective excitations of one-dimensional (1D) interacting fermions exhibit spin-charge separation, a unique feature predicted by the Tomonaga-Luttinger liquid…

Universal low energy physics in one-dimensional multicompnent Fermi gases with a strongly repulsive -function interaction
Yuzhu Jiang, Peng He, Xi-Wen Guan
It was shown [Chin. Phys. Lett. 28, 020503 (2011)] that at zero temperature the ground state of the one-dimensional (1D) -component Fermi gas coincides with that of the spinless…
