One-dimensional quantum Gibbs states in constant circuit depth
Saúl Pilatowsky-Cameo, Georgios Styliaris, Ainesh Bakshi +1
We prove that the Gibbs state of any spin chain can be exactly decomposed into a mixture of product states over contiguous blocks of qubits with bounded length, at any constant tem…
DIISC-VII: Linking Radial Gas Motions to Anomalously Low Metallicity Star-forming Regions in the XUV Disk of NGC 3344
Alejandro J. Olvera, Sanchayeeta Borthakur, Enrico M. Di Teodoro +4
We present evidence connecting anomalously low-metallicity regions to radial gas inflows in the extended ultraviolet (XUV) disk of the galaxy NGC 3344. Anomalously low-metallicity…
Emergent classicality and wavefunction branching in an isolated quantum many-body system
Saúl Pilatowsky-Cameo, Jordan Cotler, Daniel Ranard +1
Decoherence in quantum systems is conventionally modeled as the effect of interactions with an external environment. However, such a prescription excludes isolated many-body system…
Quantum thermalization achieves optimal approximate quantum error correction
Aditi Venkatesh, Richard R. Allen, Saúl Pilatowsky-Cameo +2
Quantum thermalization explains how an isolated many-body system naturally evolves towards a thermal state, rendering information about the initial conditions inaccessible to local…
Entanglement in quantum spin chains is strictly finite at any temperature
Ainesh Bakshi, Soonwon Choi, Saúl Pilatowsky-Cameo
Entanglement is the hallmark of quantum physics, yet its characterization in interacting many-body systems at thermal equilibrium remains one of the most important challenges in qu…
Critically Slow Hilbert-Space Ergodicity in Quantum Morphic Drives
Saúl Pilatowsky-Cameo, Soonwon Choi, Wen Wei Ho
The maximum entropy principle is foundational for statistical analyses of complex dynamics. This principle has been challenged by the findings of a previous work [arXiv:1701.07596]…
Quantum thermalization must occur in translation-invariant systems at high temperature
Saúl Pilatowsky-Cameo, Soonwon Choi
Quantum thermalization describes how closed quantum systems can effectively reach thermal equilibrium, resolving the apparent incongruity between the reversibility of Schrödinger's…
Classical and Quantum Properties of the Spin-Boson Dicke Model: Chaos, Localization, and Scarring
David Villaseñor, Saúl Pilatowsky-Cameo, Jorge Chávez-Carlos +4
This review article describes major developments associated with the Dicke model, from its introduction in the 1950s to explain the transition from a normal to a superradiant phase…
Hilbert-Space Ergodicity in Driven Quantum Systems: Obstructions and Designs
Saúl Pilatowsky-Cameo, Iman Marvian, Soonwon Choi +1
Despite its long history, a canonical formulation of quantum ergodicity that applies to general classes of quantum dynamics, including driven systems, has not been fully establishe…
Proposal for many-body quantum chaos detection
Adway Kumar Das, Cameron Cianci, Delmar G. A. Cabral +8
In this work, the term ``quantum chaos'' refers to spectral correlations similar to those found in the random matrix theory. Quantum chaos can be diagnosed through the analysis of…
Complete Hilbert-Space Ergodicity in Quantum Dynamics of Generalized Fibonacci Drives
Saúl Pilatowsky-Cameo, Ceren B. Dag, Wen Wei Ho +1
Ergodicity of quantum dynamics is often defined through statistical properties of energy eigenstates, as exemplified by Berry's conjecture in single-particle quantum chaos and the…
Improving Metrology with Quantum Scrambling
Zeyang Li, Simone Colombo, Chi Shu +7
Quantum scrambling describes the spreading of local information into many degrees of freedom in quantum systems. This provides the conceptual connection among diverse phenomena ran…
Chaos and Thermalization in the Spin-Boson Dicke Model
David Villaseñor, Saúl Pilatowsky-Cameo, Miguel A. Bastarrachea-Magnani +3
We present a detailed analysis of the connection between chaos and the onset of thermalization in the spin-boson Dicke model. This system has a well-defined classical limit with tw…
Effective dimensions of infinite-dimensional Hilbert spaces: A phase-space approach
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +2
By employing Husimi quasiprobability distributions, we show that a bounded portion of an unbounded phase space induces a finite effective dimension in an infinite dimensional Hilbe…
Identification of quantum scars via phase-space localization measures
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
There is no unique way to quantify the degree of delocalization of quantum states in unbounded continuous spaces. In this work, we explore a recently introduced localization measur…
Quantum localization measures in phase space
D. Villaseñor, S. Pilatowsky-Cameo, M. A. Bastarrachea-Magnani +2
Measuring the degree of localization of quantum states in phase space is essential for the description of the dynamics and equilibration of quantum systems, but this topic is far f…
Quantum scarring in a spin-boson system: fundamental families of periodic orbits
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
As the name indicates, a periodic orbit is a solution for a dynamical system that repeats itself in time. In the regular regime, periodic orbits are stable, while in the chaotic re…
Ubiquitous quantum scarring does not prevent ergodicity
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
In a classically chaotic system that is ergodic, any trajectory will be arbitrarily close to any point of the available phase space after a long time, filling it uniformly. Using B…
Quantum vs classical dynamics in a spin-boson system: manifestations of spectral correlations and scarring
D Villasenor, S Pilatowsky-Cameo, M A Bastarrachea-Magnani +3
We compare the entire classical and quantum evolutions of the Dicke model in its regular and chaotic domains. This is a paradigmatic interacting spin-boson model of great experimen…
Positive quantum Lyapunov exponents in experimental systems with a regular classical limit
Saúl Pilatowsky-Cameo, Jorge Chávez-Carlos, Miguel A. Bastarrachea-Magnani +4
Quantum chaos refers to signatures of classical chaos found in the quantum domain. Recently, it has become common to equate the exponential behavior of out-of-time order correlator…
