One-particle density matrix and momentum distribution of the out-of-equilibrium 1D Tonks-Girardeau gas: Analytical results at large
Stefano Scopa, Paola Ruggiero, Pasquale Calabrese +1
In one-dimensional (1D) quantum gases, the momentum distribution (MD) of the atoms is a standard experimental observable, routinely measured in various experimental setups. The MD…
Entanglement Rényi Entropies from Ballistic Fluctuation Theory: the free fermionic case
Giuseppe Del Vecchio Del Vecchio, Benjamin Doyon, Paola Ruggiero
The large-scale behaviour of entanglement entropy in finite-density states, in and out of equilibrium, can be understood using the physical picture of particle pairs. However, the…
Bosonization of the interacting Su-Schrieffer-Heeger model
Tony Jin, Paola Ruggiero, Thierry Giamarchi
We derive the bosonization of the interacting fermionic Su-Schrieffer-Heeger (SSH) with open boundaries. We use the classical Euler-Lagrange equations of motions of the bosonized t…
