State Diagnostics of Complexity in Open Quantum Systems
Komal Sah, Fabio Anza, Alexandra M. Jurgens +1
We study the emergence of complexity in finite-size quantum systems as their dynamics transition from closed and coherent evolution to interacting and effectively open behavior. Us…
Observable Statistical Mechanics
Lodovico Scarpa, Abdulla Alhajri, Vlatko Vedral +1
Predicting the stationary behavior of observables in isolated many-body quantum systems is a central challenge in quantum statistical mechanics. While one can often use the Gibbs e…
Branching States as The Emergent Structure of a Quantum Universe
Akram Touil, Fabio Anza, Sebastian Deffner +1
Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insigh…
Quantum Information Dimension and Geometric Entropy
Fabio Anza, James P. Crutchfield
Geometric quantum mechanics, through its differential-geometric underpinning, provides additional tools of analysis and interpretation that bring quantum mechanics closer to classi…
A kinetic theory for quantum information transport
F. Anza
In this work we build a theoretical framework for the transport of information in quantum systems. This is a framework aimed at describing how out of equilibrium open quantum syste…
Quantifying the difference between many-body quantum states
Davide Girolami, Fabio Anzà
The quantum state overlap is the textbook measure of the difference between two quantum states. Yet, it is inadequate to compare the complex configurations of many-body systems. Th…
Szilard Engines as Quantum Thermodynamical Systems
Maryam Ashrafi, Kyle J. Ray, Fabio Anza +1
We analyze an engine whose working fluid consists of a single quantum particle, paralleling Szilard's construction of a classical single-particle engine. Following his resolution o…
Beyond Density Matrices: Geometric Quantum States
Fabio Anza, James P. Crutchfield
A quantum system's state is identified with a density matrix. Though their probabilistic interpretation is rooted in ensemble theory, density matrices embody a known shortcoming. T…
Geometric Quantum Thermodynamics
Fabio Anza, James P. Crutchfield
Building on parallels between geometric quantum mechanics and classical mechanics, we explore an alternative basis for quantum thermodynamics that exploits the differential geometr…
Maximum Geometric Quantum Entropy
Fabio Anza, James P. Crutchfield
Any given density matrix can be represented as an infinite number of ensembles of pure states. This leads to the natural question of how to uniquely select one out of the many, app…
Logarithmic growth of local entropy and total correlations in many-body localized dynamics
Fabio Anza, Francesca Pietracaprina, John Goold
The characterizing feature of a many-body localized phase is the existence of an extensive set of quasi-local conserved quantities with an exponentially localized support. This str…
New equilibrium ensembles for isolated quantum systems
Fabio Anza
The unitary dynamics of isolated quantum systems does not allow a pure state to thermalize. Because of that, if an isolated quantum system equilibrates, it will do so to the predic…
Pure states statistical mechanics: On its foundations and applications to quantum gravity
Fabio Anza
The project concerns the interplay among quantum mechanics, statistical mechanics and thermodynamics, in isolated quantum systems. The underlying goal is to improve our understandi…
Degenerate observables and the many Eigenstate Thermalization Hypotheses
Fabio Anza, Christian Gogolin, Marcus Huber
Under unitary time evolution, expectation values of physically reasonable observables often evolve towards the predictions of equilibrium statistical mechanics. The eigenstate ther…
On the fate of the Hoop Conjecture in quantum gravity
Fabio Anzà, Goffredo Chirco
We consider a closed region of 3d quantum space modeled by spin-networks. Using the concentration of measure phenomenon we prove that, whenever the ratio between the bo…
Typicality in spin network states of quantum geometry
Fabio Anzà, Goffredo Chirco
In this work, we extend the so-called typicality approach, originally formulated in statistical mechanics contexts, to -invariant spin-network states. Our results do not dep…
Search for Resonances Decaying to Top and Bottom Quarks with the CDF Experiment
CDF Collaboration, T. Aaltonen, S. Amerio +402
We report on a search for charged massive resonances decaying to top () and bottom () quarks in the full data set of proton-antiproton collisions at center-of-mass energy of…
Resonant transitions due to changing boundaries
F. Anzà, A. Messina, B. Militello
The problem of a particle confined in a box with moving walls is studied, focusing on the case of small perturbations which do not alter the shape of the boundary (\lq pantography\…
A note on the secondary simplicity constraints in loop quantum gravity
Fabio Anzà, Simone Speziale
A debate has appeared in the literature on loop quantum gravity and spin foams, over whether the secondary simplicity constraints, reducing the connection to be Levi-Civita, should…
Dynamics of a particle confined in a two-dimensional dilating and deforming domain
F. Anzà, S. Di Martino, A. Messina +1
Some recent results concerning a particle confined in a one-dimensional box with moving walls are briefly reviewed. By exploiting the same techniques used for the 1D problem, we in…
A quantum particle in a box with moving walls
Sara Di Martino, Fabio Anza', Paolo Facchi +5
We analyze the non-relativistic problem of a quantum particle that bounces back and forth between two moving walls. We recast this problem into the equivalent one of a quantum part…
Tripartite thermal correlations in an inhomogeneous spin-star system
F. Anzà, B. Militello, A. Messina
We exploit the tripartite negativity to study the thermal correlations in a tripartite system, that is the three outer spins interacting with the central one in a spin-star system.…
