Numerical Simulation of Finite-Temperature Field Theory for Interacting Bosons.
A stable and efficient complex Langevin sampling scheme for performing approximation-free numerical simulations directly on the path-integral coherent-states field theory for an assembly of interacting bosons and a new approach enjoys near-linear scaling in the resolved (d+1) spatial and imaginary-time dimensions.

Gauge-free Hamiltonian structure of the spin Maxwell-Vlasov equations
Abstract We derive the gauge-free Hamiltonian structure of an extended kinetic theory, for which the intrinsic spin of the particles is taken into account. Such a semi-classical theory can be ofExpand
Know the enemy: 2D Fermi liquids
Abstract We describe an analytical theory investigating the regime of validity of the Fermi liquid theory in interacting, via the long-range Coulomb coupling, two-dimensional Fermi systems comparingExpand
Spin switching: From quantum to quasiclassical approach
In this paper, we review the theory of spin switching for systems of different sizes, from a quantum mechanical master equation approach for small atomic clusters to the quasiclassical description ofExpand
Bosonic superfluid transport in a quantum point contact
We present a microscopic theory of heat and particle transport of an interacting, low temperature Bose-Einstein condensate in a quantum point contact. We show that, in contrast to charged, fermionicExpand
Coherent phonon dynamics of normal metal in ultrafast spectroscopy: Non-equilibrium gauge invariant Green's function approach
Abstract The phonon dynamics of normal metal in the coherent regime of ultrafast spectroscopy is studied based on the non-equilibrium gauge invariant Green's function method. The non-equilibriumExpand
Sinai Diffusion at Quasi-1D Topological Phase Transitions.
The expected manifestations of this transport mechanism for heat propagation in topological superconductors near criticality are discussed and a microscopic theory explaining the phenomenon is provided. Expand
Quantum dissipation in a scalar field theory with gapped momentum states
This work treats dissipation non-perturbatively, represents it by a bilinear term in the Lagrangian and quantize the theory, and finds that dissipation promotes a gap in momentum space and reduces the particle energy. Expand
Quench dynamics of one-dimensional interacting bosons in a disordered potential: elastic dephasing and critical speeding-up of thermalization.
Thermalization turns out to be most effective close to the superfluid-Bose-glass critical point where nonlinearities become more and more important. Expand
