Observation of -tails after expansion of Bose-Einstein Condensates with impurities
Hugo Cayla, Pietro Massignan, Thierry Giamarchi +3
We measure the momentum density in a Bose-Einstein condensate (BEC) with dilute spin impurities after an expansion in the presence of interactions. We observe tails decaying as $1/…
Superfluid vortex dynamics on an ellipsoid and other surfaces of revolution
Mônica A. Caracanhas, Pietro Massignan, Alexander L. Fetter
We study the dynamics of quantized superfluid vortices on axisymmetric compact surfaces with no holes, where the total vortex charge must vanish and the condition of irrotational f…
Superfluid vortex dynamics on a spherical film
Sálvio Jacob Bereta, Mônica A. Caracanhas, Alexander L. Fetter
Motivated by ongoing experimental efforts to make closed Bose-Einstein condensate (BEC) shells in microgravity environments, this work studies the energy and dynamics of singly qua…
Measuring topological invariants in polaritonic graphene
P. St-Jean, A. Dauphin, P. Massignan +10
Topological materials rely on engineering global properties of their bulk energy bands called topological invariants. These invariants, usually defined over the entire Brillouin zo…
Quantum Brownian Motion with Inhomogeneous Damping and Diffusion
Pietro Massignan, Aniello Lampo, Jan Wehr +1
We analyze the microscopic model of quantum Brownian motion, describing a Brownian particle interacting with a bosonic bath through a coupling which is linear in the creation and a…
Atomic wave packet dynamics in finite time-dependent optical lattices
T Lauber, P Massignan, G Birkl +1
Atomic wave packets in optical lattices which are both spatially finite and time-dependent exhibit many striking similarities with light pulses in photonic crystals. We analyticall…
