Analytical solution of a free-fermion chain with time-dependent ramps
Viktor Eisler, Riccarda Bonsignori, Stefano Scopa
We provide an exact analytical solution of the single-particle Schrödinger equation for a chain of non-interacting fermions subject to a time-dependent linear potential, with its s…
Enhanced correlations due to ballistic transport
Damiano De Angelis, Jacopo De Nardis, Stefano Scopa
We investigate the nature of density-density correlations in a 1D gas of hard-core particles initially prepared at equilibrium (either at zero or finite temperature) on a semi-infi…
One-body correlations and momentum distributions of trapped one-dimensional Bose gases at finite temperature
Attila Takács, Yicheng Zhang, Pasquale Calabrese +3
We introduce a general approximate method for calculating the one-body correlations and the momentum distributions of one-dimensional Bose gases at finite interaction strengths and…
Quantum fluctuating theory for one-dimensional shock waves
Andrew Urilyon, Stefano Scopa, Giuseppe Del Vecchio Del Vecchio +1
We study the formation and the subsequent dynamics of shock waves in repulsive one-dimensional Bose gases during the free expansion of a density hump. By building coherent Fermi st…
Quasicondensation and off-diagonal long-range order of hard-core bosons during a free expansion
A. Takács, S. Scopa, P. Calabrese +2
Quasicondensation in one dimension is known to occur for equilibrium systems of hard-core bosons (HCBs) at zero temperature. This phenomenon arises due to the off-diagonal long-ran…
Scaling of fronts and entanglement spreading during a domain wall melting
Stefano Scopa, Dragi Karevski
We revisit the out-of-equilibrium physics arising during the unitary evolution of a one-dimensional XXZ spin chain initially prepared in a domain wall state $\vertψ_0\rangle=\vert\…
