Counterflow leads to roton spectra in locally interacting superfluids
Samuel Alperin, Eddy Timmermans
The dynamics of strongly interacting quantum fluids such as Helium II are fundamentally distinct from those of dilute, contact-interacting atomic Bose-Einstein condensates. Most dr…
Single impurities in a Bose-Einstein condensate can make two polaron flavors
A. A. Blinova, M. G. Boshier, Eddy Timmermans
Polarons, self-localized composite objects formed by the interaction of a single impurity particle with a host medium, are a paradigm of strong interaction many-body physics. We sh…
Roton immiscibility in a two-component dipolar Bose gas
Ryan M. Wilson, Christopher Ticknor, John L. Bohn +1
We characterize the immiscibility-miscibility transition (IMT) of a two-component Bose-Einstein condensate (BEC) with dipole-dipole interactions. In particular, we consider the qua…
Large-N approximation for single- and two-component dilute Bose gases
Chih-Chun Chien, Fred Cooper, Eddy Timmermans
We discuss the mean-field theories obtained from the leading order in a large- approximation for one- and two- component dilute Bose gases. For a one-component Bose gas this app…
Novel Polaron State for Single Impurity in a Bosonic Mott Insulator
Yasuyuki Kato, K. A. Al-Hassanieh, A. E. Feiguin +2
We show that a single impurity embedded in a cold atom bosonic Mott insulator leads to a novel polaron that exhibits correlated motion with an effective mass and a linear size that…
Composite-Field Goldstone States and Higgs Mechanism in Dilute Bose Gases
Fred Cooper, Chih-Chun Chien, Bogdan Mihaila +2
We show that a composite-field (diatom) Goldstone state is expected in a dilute Bose gas for temperatures between the Bose gas critical temperature where the atom Bose-Einstein con…
