Breakdown of Fermi's Golden Rule in 1d systems at non-zero temperature
Thomas Young, Jerome LLoyd, Curt von Keyserlingk
In interacting quantum systems, the single-particle Green's function is expected to decay in time due to the interaction induced decoherence of quasiparticles. In the limit of weak…

The ballistic to diffusive crossover in a weakly-interacting Fermi gas
Jerome Lloyd, Tibor Rakovszky, Frank Pollmann +1
Charge and energy are expected to diffuse in interacting systems of fermions at finite temperatures, even in the absence of disorder, with the interactions inducing a crossover fro…
