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…
One second interrogation time in a 200 round-trip waveguide atom interferometer
Hyosub Kim, Katarzyna Krzyzanowska, K. C. Henderson +3
We report a multiple-loop guided atom interferometer in which the atoms make 200 small-amplitude roundtrips, instead of one large single orbit. The approach is enabled by using ult…
Stroboscopic aliasing in long-range interacting quantum systems
Shane P. Kelly, Eddy Timmermans, Jamir Marino +1
We unveil a mechanism for generating oscillations with arbitrary multiplets of the period of a given external drive, in long-range interacting quantum many-particle spin systems. T…
Thermalization and its Breakdown for a Large Nonlinear Spin
Shane P. Kelly, Eddy Timmermans, S. -W. Tsai
By developing a semi-classical analysis based on the Eigenstate Thermalization Hypothesis, we determine the long time behavior of a large spin evolving with a nonlinear Hamiltonian…
Detecting Macroscopic Indefiniteness of Cat States in Bosonic Interferometers
Shane P. Kelly, Eddy Timmermans, S. W. Tsai
The paradigm of Schrödinger's cat illustrates how quantum states preclude the assignment of definite properties to a macroscopic object (realism). In this work we develop a method…
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…
