Quantum Stochastic Walks on the Permutation Group

Feng He, Arthur Hutsalyuk, Giuseppe Mussardo +1

How rapidly does order give way to randomness, and can quantum coherence accelerate this process? We address these questions through the paradigmatic problem of card shuffling, for…

Spectral Decimation of Quantum Many-Body Hamiltonians

Feng He, Arthur Hutsalyuk, Giuseppe Mussardo +1

We develop a systematic theory of spectral decimation for quantum many-body Hamiltonians and show that it provides a quantitative probe of emergent symmetries in statistically mixe…

Variational Method in Quantum Field Theory

Arthur Hutsalyuk, Márton Lájer, Giuseppe Mussardo +1

We develop a variational framework for addressing two-dimensional non-integrable quantum field theories through the exact structure of their integrable counterparts. Concentrating…

Statistical Signatures of Integrable and Non-Integrable Quantum Hamiltonians

Feng He, Arthur Hutsalyuk, Giuseppe Mussardo +1

Integrability is a cornerstone of classical mechanics, where it has a precise meaning. Extending this notion to quantum systems, however, remains subtle and unresolved. In particul…

Discrete-to-Continuum Approach for the Analytic Continuation of One-Particle Propagator on the Circle

Andrea Stampiggi

Despite the simplicity of one-particle dynamics, explicit expressions for the one-dimensional propagator on a circle suitable to numerical evaluation are surprisingly lacking -- no…

Reflection and Transmission Amplitudes in a Digital Quantum Simulation

Giuseppe Mussardo, Andrea Stampiggi, Andrea Trombettoni

In this paper we show how to measure in the setting of digital quantum simulations the reflection and transmission amplitudes of the one-dimensional scattering of a particle with a…
