Equilibration and the eigenstate thermalization hypothesis as limits to observing macroscopic quantum superpositions

Gabriel Dias Carvalho, Pedro S. Correia, Thiago R. de Oliveira

Macroscopic quantum superpositions are widely believed to be unobservable because large systems cannot be perfectly isolated from their environments. Here, we show that even under…

Equivalence of Stabilizer and Shannon Rényi Entropies: Exact Results for Quantum Critical Chains

E. A. Ramirez Trino, M. A. Rajabpour

Shannon-Rényi and stabilizer entropies are key diagnostics of structure, ``nonstabilizerness,'' phase transitions, and universality in quantum many-body states. We establish an exa…

Efficient computation of average subsystem Bures distance between fermionic Gaussian states

Zhouhao Guo, M. A. Rajabpour, Jiaju Zhang

The average subsystem trace distance has been proposed as an indicator of quantum many-body chaos and integrability. However, evaluating it presents two main difficulties: high com…

Exact analysis of AC sensors based on Floquet time crystals

Andrei Tsypilnikov, Matheus Fibger, Fernando Iemini

We discuss the behavior of general Floquet time crystals (FTCs), including prethermal ones, in closed systems acting as AC sensors. We provide an analytical treatment of their quan…

Tailoring the van der Waals interaction with rotation

H. S. G. Amaral, P. P. Abrantes, F. Impens +2

We report a systematic procedure to engineer the van der Waals force between levitated nanoparticles in high vacuum by setting them into a fast rotation. By tuning the rotation fre…

: an automated algebraic solution for high-order quantum systems

D. Martínez-Tibaduiza, Vladimir Vargas-Calderón, J. G. Dueñas +2

Many significant quantum physical systems are characterized by Hamiltonians expressible as a linear combination of time-independent generators of a closed Lie algebra, $\hat{H}(t)=…

Necessity of entanglement for the typicality argument in statistical mechanics

Pedro S. Correia, Gabriel Dias Carvalho, Thiago R. de Oliveira

Typicality arguments replace the postulated mixed state ensembles of statistical mechanics with pure states sampled uniformly at random, explaining why most microstates of large sy…

Roadmap on Quantum Thermodynamics

Steve Campbell, Irene D'Amico, Mario A. Ciampini +66

The last two decades has seen quantum thermodynamics become a well established field of research in its own right. In that time, it has demonstrated a remarkably broad applicabilit…

Ergotropy-Based Quantum Thermodynamics

J. M. Z. Choquehuanca, P. A. C. Obando, M. S. Sarandy +1

We introduce an ergotropy-based formulation of quantum thermodynamics, which provides a strong connection between average heat and von Neumann entropy. By adopting this formulation…

Two-particle scattering on general graphs

Luna Lima Keller, Daniel Jost Brod

Quantum walks in general graphs, or more specifically scattering on graphs, encompass enough complexity to perform universal quantum computation. Any given quantum circuit can be b…

Computing band gaps of periodic materials via sample-based quantum diagonalization

Alan Duriez, Pamela C. Carvalho, Marco Antonio Barroca +7

A key objective of computational solid state physics is to predict electronic properties of periodic materials. However, electronic structure simulations based on density functiona…

Explicit Pfaffian Formula for Amplitudes of Fermionic Gaussian Pure States in Arbitrary Pauli Bases

M. A. Rajabpour, M. A. Seifi Mirjafarlou, Reyhaneh Khasseh

The explicit computation of amplitudes for fermionic Gaussian pure states in arbitrary Pauli bases is a long-standing challenge in quantum many-body physics, with significant impli…

Are Hilbert Spaces Unphysical? Hardly, My Dear!

Nivaldo A. Lemos

It is widely accepted that the states of any quantum system are vectors in a Hilbert space. Not everyone agrees, however. The recent paper ``The unphysicality of Hilbert spaces'' b…
