Non-adiabacity and large flucutations in a many particle Landau Zener problem
A. Altland, V. Gurarie, T. Kriecherbauer +1
We consider the behavior of an interacting many particle system under slow external driving -- a many body generalization of the Landau-Zener paradigm. We find that a conspiracy of…
Interferometric probe of paired states
V. Gritsev, E. Demler, A. Polkovnikov
We propose a new method for detecting paired states in either bosonic or fermionic systems using interference experiments with independent or weakly coupled low dimensional systems…
Microscopic diagonal entropy and its connection to basic thermodynamic relations
Anatoli Polkovnikov
We define a diagonal entropy (d-entropy) for an arbitrary Hamiltonian system as with the sum taken over the basis of instantaneous energy states. In…
Microscopic expression for the heat in the adiabatic basis
Anatoli Polkovnikov
We derive a microscopic expression for the instantaneous diagonal elements of the density matrix in the adiabatic basis for an arbitrary time dependent process in a clo…
Optimal non-linear passage through a quantum critical point
Roman Barankov, Anatoli Polkovnikov
We analyze the problem of optimal adiabatic passage through a quantum critical point. We show that to minimize the number of defects the tuning parameter should be changed as a pow…
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…
