SU(1,1) echoes for breathers in quantum gases
Chenwei Lv, Ren Zhang, Qi Zhou
Though the celebrated spin echoes have been widely used to reverse quantum dynamics, they are not applicable to systems whose constituents are beyond the control of the su(2) algeb…

Universal relations for ultracold reactive molecules
Mingyuan He, Chenwei Lv, Hai-Qing Lin +1
The realization of ultracold polar molecules in laboratories has pushed both physics and chemistry to new realms. In particular, these polar molecules offer scientists unprecedente…

Geometrizing quantum dynamics of a Bose-Einstein condensate
Changyuan Lyu, Chenwei Lv, Qi Zhou
We show that quantum dynamics of Bose-Einstein condensates in the weakly interacting regime can be geometrized by a Poincaré disk. Each point on such a disk represents a thermofiel…
