Adiabatic nonlinear probes of one-dimensional Bose gases
C. De Grandi, R. A. Barankov, A. Polkovnikov
We discuss two complementary problems: adiabatic loading of one-dimensional bosons into an optical lattice and merging two one-dimensional Bose systems. Both problems can be mapped…
Coexistence of superfluid and Mott phases of lattice bosons
R. A. Barankov, C. Lannert, S. Vishveshwara
Recent experiments on strongly-interacting bosons in optical lattices have revealed the co-existence of spatially-separated Mott-insulating and number-fluctuating phases. The descr…
Synchronization in the BCS Pairing Dynamics as a Critical Phenomenon
R. A. Barankov, L. S. Levitov
Fermi gas with time-dependent pairing interaction hosts several different dynamical states. Coupling between the collective BCS pairing mode and individual Cooper pair states can m…
Atom-molecule coexistence and collective dynamics near a Feshbach resonance of cold fermions
R. A. Barankov, L. S. Levitov
Degenerate Fermi gas interacting with molecules near Feshbach resonance is unstable with respect to formation of a mixed state in which atoms and molecules coexist as a coherent su…
Solitons and Rabi Oscillations in a Time-Dependent BCS Pairing Problem
R A Barankov, L S Levitov, B Z Spivak
Motivated by recent efforts to achieve cold fermions pairing near a Feshbach resonance, we consider the dynamics of formation of the Bardeen-Cooper-Schrieffer (BCS) state. At times…
