Self-organized quasicrystals and their excitations in dipolar Bose-Einstein condensates via optical feedback
Liang-Jun He, Fabian Maucher, Yong-Chang Zhang
Quasicrystals emerge from competing interactions with incommensurate characteristic length scales that inhibit translational periodicity. Here, we show that such multiscale interac…
The Solid-state Physics of Rydberg-dressed Bosonic Mixtures
Yi-Ming Duan, Liang-Jun He, Fabian Maucher +1
We explore phases of two-component Rydberg-dressed Bose-Einstein condensates in three spatial dimensions. The competition between the effective ranges of inter- and intra-component…
Nonreciprocal and long-range three-body interactions in Bose-Einstein condensates induced by optical feedback
Yi-Qing Zhang, Liang-Jun He, Han Pu +2
We propose generating long-range and nonreciprocal three-body interactions in quantum gases via optical feedback. By placing a quasi-two-dimensional Bose-Einstein condensate (BEC)…
Accessing elusive two-dimensional phases of dipolar Bose-Einstein condensates by finite temperature
Liang-Jun He, Juan Sanchez-Baena, Fabian Maucher +1
It has been shown that dipolar Bose-Einstein condensates that are tightly trapped along the polarization direction can feature a rich phase diagram. In this paper we show that fini…
On the infrared cutoff for dipolar droplets
Liang-Jun He, Fabian Maucher, Yong-Chang Zhang
The beyond mean-field physics due to quantum fluctuations is often described by the Lee-Huang-Yang (LHY) correction, which can be approximately written as a simple analytical expre…
Quantum droplets in dipolar condensate mixtures with arbitrary dipole orientations
Liang-Jun He, Bo Liu, Yong-Chang Zhang
Through considering a two-component dipolar Bose-Einstein condensate, we investigate the influence of the angle between the polarization orientations of the two species on the grou…
