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…
Mediated Interactions and Damping Effects in Superfluid Mixtures of Bose and Fermi Gases
Dong-Chen Zheng, Yu-Xin Liao, Wen Lin +1
We investigate the homogeneous superfluid mixtures of Bardeen-Cooper-Schrieffer~(BCS) superfluid originating from pairing two-species fermionic atoms and superfluidity stemming fro…
Theoretical Exploration of Phase Transitions in a Cavity-BEC System with Two Crossed Optical Pumps
Wei Qin, Dong-Chen Zheng, Zhao-Di Wu +2
We consider a Bose-Einstein condensation (BEC) inside an optical cavity and two crossed coherent pump fields. We determine the phase boundary separating the normal superfluid phase…
Quantum Triticality of Bosonic Atomic-Molecular Mixtures with Feshbach Coupling
Yuan-Hong Chen, Dong-Chen Zheng, Renyuan Liao
We develop a functional integral formulation for a homogeneous bosonic atomic-molecular mixture with Feshbach coupling in three-spatial dimensions. Taking phase stability into acco…
Polarizing the Medium: Fermion-Mediated Interactions between Bosons
Dong-Chen Zheng, Lin Wen, Chun-Rong Ye +1
We consider a homogeneous mixture of bosons and polarized fermions. We find that long-range and attractive fermion-mediated interactions between bosons have dramatic effects on the…
Tuning Dissipation and Excitations in Superfluid Fermi Gases with a Moving Impurity
Dong-Chen Zheng, Yan-Qiang Yu, Renyuan Liao
We develop a method to extract the dissipation for a heavy moving impurity immersed in superfluid Fermi gases. The drag force is derived analytically. As a reward, we are able to e…
Theoretical exploration of competing phases of lattice Bose gases in a cavity
Renyuan Liao, Huang-Jie Chen, Dong-Chen Zheng +1
We consider bosonic atoms loaded into optical lattices with cavity-mediated infinite-range interactions. Competing short- and global-range interactions cultivates a rich phase diag…
