Observing dissipationless flow of an impurity in a strongly repulsive quantum fluid
Milena Horvath, Sudipta Dhar, Elisabeth Wybo +6
The frictionless motion of an object through a fluid medium is commonly viewed as a hallmark of superfluidity. According to Landau, kinematic constraints prohibit superfluid behavi…

Repeated Measurements with Minimally Destructive Partial-Transfer Absorption Imaging
Erin Marshall Seroka, Ana Valdés Curiel, Dimitrios Trypogeorgos +2
We demonstrate partial-transfer absorption imaging as a technique for repeatedly imaging an ultracold atomic ensemble with minimal perturbation. We prepare an atomic cloud in a sta…

Perpetual emulation threshold of PT-symmetric Hamiltonians
D. Trypogeorgos, A. Valdés-Curiel, I. B. Spielman +1
We describe a technique to emulate a two-level \PT-symmetric spin Hamiltonian, replete with gain and loss, using only the unitary dynamics of a larger quantum system. This we achie…
