Dissipative dynamics and cooling rates of trapped impurity atoms immersed in a reservoir gas
R. G. Lena, A. J. Daley
We study the dissipative dynamics of neutral atoms in anisotropic harmonic potentials, immersed in a reservoir species that is not trapped by the harmonic potential. Considering in…

Observation of Non-equilibrium Motion and Equilibration in Polariton Rings
S. Mukherjee, D. M. Myers, R. G. Lena +8
We present a study of the macroscopic dynamics of a polariton condensate formed by non-resonant optical excitation in a quasi-one-dimensional ring-shaped microcavity. The presence…

Work Fluctuations in Bosonic Josephson Junctions
R. G. Lena, G. M. Palma, G. De Chiara
We calculate the first two moments and full probability distribution of the work performed on a system of bosonic particles in a two-mode Bose-Hubbard Hamiltonian when the self-int…
