Transient fluctuation relations for time-dependent particle transport
A. Altland, A. De Martino, R. Egger +1
We consider particle transport under the influence of time-varying driving forces, where fluctuation relations connect the statistics of pairs of time reversed evolutions of physic…
Four-body problem and BEC-BCS crossover in a quasi-one-dimensional cold fermion gas
C. Mora, A. Komnik, R. Egger +1
The four-body problem for an interacting two-species Fermi gas is solved analytically in a confined quasi-one-dimensional geometry, where the two-body atom-atom scattering length $…
Three-body problem for ultracold atoms in quasi-one-dimensional traps
C. Mora, R. Egger, A. O. Gogolin
We study the three-body problem for both fermionic and bosonic cold atom gases in a parabolic transverse trap of lengthscale . For this quasi-one-dimensional (1D) problem,…
Exact results for one-dimensional disordered bosons with strong repulsion
A. De Martino, M. Thorwart, R. Egger +1
We study one-dimensional incommensurate bosons with strong repulsive interactions and weak disorder. In analogy to the clean Tonks-Girardeau gas, a Bose-Fermi mapping expresses thi…
Multilevel blocking approach to the fermion sign problem in path-integral Monte Carlo simulations
C. H. Mak, R. Egger, H. Weber-Gottschick
A general algorithm toward the solution of the fermion sign problem in finite-temperature quantum Monte Carlo simulations has been formulated for discretized fermion path integrals…
