Negativity Spectrum in the Random Singlet Phase
Xhek Turkeshi, Paola Ruggiero, Pasquale Calabrese
Entanglement features of the ground state of disordered quantum matter are often captured by an infinite randomness fixed point that, for a variety of models, is the random singlet…
Quantum Generalized Hydrodynamics
Paola Ruggiero, Pasquale Calabrese, Benjamin Doyon +1
Physical systems made of many interacting quantum particles can often be described by Euler hydrodynamic equations in the limit of long wavelengths and low frequencies. Recently su…
Symmetry resolved entanglement in free fermionic systems
Riccarda Bonsignori, Paola Ruggiero, Pasquale Calabrese
We consider the symmetry resolved Rényi entropies in the one dimensional tight binding model, equivalent to the spin-1/2 XX chain in a magnetic field. We exploit the generalised Fi…
Subsystem trace distance in low-lying states of -dimensional conformal field theories
Jiaju Zhang, Paola Ruggiero, Pasquale Calabrese
We report on a systematic replica approach to calculate the subsystem trace distance for a quantum field theory. This method has been recently introduced in [J. Zhang, P. Ruggiero,…
Twisted and untwisted negativity spectrum of free fermions
Hassan Shapourian, Paola Ruggiero, Shinsei Ryu +1
A basic diagnostic of entanglement in mixed quantum states is known as the positive partial transpose (PT) criterion. Such criterion is based on the observation that the spectrum o…
Subsystem Trace Distance in Quantum Field Theory
Jiaju Zhang, Paola Ruggiero, Pasquale Calabrese
We develop a systematic method to calculate the trace distance between two reduced density matrices in 1+1 dimensional quantum field theories. The approach exploits the path integr…
Conformal field theory on top of a breathing one-dimensional gas of hard core bosons
Paola Ruggiero, Yannis Brun, Jérome Dubail
The recent results of [J. Dubail, J.-M. Stéphan, J. Viti, P. Calabrese, Scipost Phys. 2, 002 (2017)], which aim at providing access to large scale correlation functions of inhomoge…
