Asymptotic Freedom of Two Heavy Impurities in a Bose-Einstein Condensate
Dong-Chen Zheng, Lin Wen, Renyuan Liao
We consider two heavy impurities immersed in a Bose-Einstein condensate, and calculate the self-energy using the Wilsonian renormalization. The polaron energy, quasiparticle residu…

Exotic localization for the bound states in the non-reciprocal two-particle Hubbard model
Huan-Yu Wang, Ji Li, Wu-Ming Liu +2
We investigate the localization behavior of two-particle Hubbard model in the presence of non-reciprocal tunneling and non-Hermitian bound states can be obtained with strong repuls…
