From few- to many-body quantum systems
Mauro Schiulaz, Marco Távora, Lea F. Santos
How many particles are necessary to make a quantum system many-body? To answer this question, we take as reference for the many-body limit a quantum system at half-filling and comp…
Power-law decay exponents: a dynamical criterion for predicting thermalization
Marco Távora, E. J. Torres-Herrera, Lea F. Santos
From the analysis of the relaxation process of isolated lattice many-body quantum systems quenched far from equilibrium, we deduce a criterion for predicting when they are certain…
Realistic many-body quantum systems vs full random matrices: static and dynamical properties
E. J. Torres-Herrera, Jonathan Karp, Marco Távora +1
We study the static and dynamical properties of isolated many-body quantum systems and compare them with the results for full random matrices. In doing so, we link concepts from qu…
Short-time universal scaling and light-cone dynamics after a quench in an isolated quantum system in spatial dimensions
Alessio Chiocchetta, Marco Tavora, Andrea Gambassi +1
We investigate the effects of fluctuations on the dynamics of an isolated quantum system represented by a field theory with symmetry after a quench in spatial di…
Excited-state quantum phase transitions in many-body systems with infinite-range interaction: Localization, dynamics, and bifurcation
Lea F. Santos, Marco Távora, Francisco Pérez-Bernal
Excited state quantum phase transitions (ESQPTs) are generalizations of quantum phase transitions (QPTs) to excited levels. They are associated with local divergences in the densit…
Inevitable Power-law Behavior of Isolated Many-Body Quantum Systems and How It Anticipates Thermalization
Marco Távora, E. J. Torres-Herrera, Lea F. Santos
Despite being ubiquitous, out-of-equilibrium quantum systems are much less understood than systems at equilibrium. Progress in the field has benefited from a symbiotic relationship…
Survival Probability of the Néel State in Clean and Disordered Systems: an Overview
E. J. Torres-Herrera, Marco Távora, Lea F. Santos
In this work we provide an overview of our recent results about the quench dynamics of one-dimensional many-body quantum systems described by spin-1/2 models. To illustrate those g…
Short-time universal scaling in an isolated quantum system after a quench
Alessio Chiocchetta, Marco Tavora, Andrea Gambassi +1
Renormalization-group methods provide a viable approach for investigating the emergent collective behavior of classical and quantum statistical systems in both equilibrium and none…
Quench dynamics of one-dimensional interacting bosons in a disordered potential: Elastic dephasing and critical speeding-up of thermalization
Marco Tavora, Achim Rosch, Aditi Mitra
The dynamics of interacting bosons in one dimension following the sudden switching on of a weak disordered potential is investigated. On time scales before quasiparticles scatter (…
Quench dynamics of one-dimensional bosons in a commensurate periodic potential: A quantum kinetic equation approach
Marco Tavora, Aditi Mitra
Results are presented for the dynamics arising due to a sudden quench of a boson interaction parameter with the simultaneous switching on of a commensurate periodic potential, the…
