Non-equilibrium universality in the dynamics of dissipative cold atomic gases
Matteo Marcuzzi, Emanuele Levi, Weibin Li +3
The theory of continuous phase transitions predicts the universal collective properties of a physical system near a critical point, which for instance manifest in characteristic po…
Universal non-equilibrium properties of dissipative Rydberg gases
M. Marcuzzi, E. Levi, S. Diehl +2
We investigate the out-of-equilibrium behavior of a dissipative gas of Rydberg atoms that features a dynamical transition between two stationary states characterized by different e…
Entanglement Entropy of Non Unitary Conformal Field Theory
Davide Bianchini, Olalla A. Castro-Alvaredo, Benjamin Doyon +2
In this letter we show that the Rényi entanglement entropy of a region of large size in a one-dimensional critical model whose ground state breaks conformal invariance (such…
Cumulants of time-integrated observables of closed quantum systems and PT-symmetry, with an application to the quantum Ising chain
James M. Hickey, Emanuele Levi, Juan P. Garrahan
We study the connection between the cumulants of a time-integrated observable of a quantum system and the PT-symmetry properties of the non-Hermitian deformation of the Hamiltonian…
Non-classical correlations in a class of spin chains with long-range interactions and exactly solvable ground states
Emanuele Levi, Igor Lesanovsky
We introduce a class of spin models with long-range interactions---in the sense that they extend significantly beyond nearest neighbors---whose ground states can be constructed ana…
