Converting Long-Range Entanglement into Mixture: Tensor-Network Approach to Local Equilibration

Marcelo Castellanos2025-04-28T11:13:31+02:00Tags: Multidisciplinary. , Physics|

Authors: Frias-Perez, Miguel; Tagliacozzo, Luca; Banuls, Mari Carmen Journal: PHYSICAL REVIEW LETTERS Publication date: 2024/03/08 DOI: 10.1103/PhysRevLett.132.100402 Abstract: In the out-of-equilibrium evolution induced by a quench, fast degrees of freedom generate long-range entanglement that is hard to encode with standard tensor networks. However, local observables only sense such long-range correlations through their contribution to the [...]

Edge-dependent anomalous topology in synthetic photonic lattices subject to discrete step walks

Authors: El Sokhen, Rabih; Gomez-Leon, Alvaro; Adiyatullin, Albert F.; Randoux, Stephane; Delplace, Pierre; Amo, Alberto Journal: PHYSICAL REVIEW RESEARCH Publication date: 2024/06/17 DOI: 10.1103/PhysRevResearch.6.023282 Abstract: Anomalous topological phases, where edge states coexist with topologically trivial Chern bands, can only appear in periodically driven lattices. When the driving is smooth and continuous, the bulk-edge correspondence is [...]

Authors: de Oca-Estevez, Maria Judit Montes; Prosmiti, Rita Journal: MOLECULES Publication date: 2024/09/01 DOI: 10.3390/molecules29174084 Abstract: We present a computational investigation on the structural arrangements and energetic stabilities of small-size protonated argon clusters, ArnH+. Using high-level ab initio electronic structure computations, we determined that the linear symmetric triatomic ArH+ Ar ion serves as the molecular [...]

Quantum battery supercharging via counter-diabatic dynamics

Authors: de Moraes, L. F. C.; Duriez, Alan C.; Saguia, A.; Santos, Alan C.; Sarandy, M. S. Journal: QUANTUM SCIENCE AND TECHNOLOGY Publication date: 2024/10/01 DOI: 10.1088/2058-9565/ad71ed Abstract: We introduce a counter-diabatic (CD) approach for deriving Hamiltonians modeling superchargable quantum batteries (QBs). A necessary requirement for the supercharging process is the existence of multipartite interactions [...]

Photonic quantum metrology with variational quantum optical nonlinearities

Authors: de las Heras, A. Munoz; Tabares, C.; Schneider, J. T.; Tagliacozzo, L.; Porras, D.; Gonzalez-Tudela, A. Journal: PHYSICAL REVIEW RESEARCH Publication date: 2024/03/19 DOI: 10.1103/PhysRevResearch.6.013299 Abstract: Photonic quantum metrology harnesses quantum states of light, such as NOON or twin-Fock states, to measure unknown parameters beyond classical precision limits. Current protocols suffer from two severe [...]

An Ab Initio Journey toward the Molecular-Level Understanding and Predictability of Subnanometric Metal Clusters

Marcelo Castellanos2025-04-28T11:13:19+02:00Tags: Chemistry, Multidisciplinary. , Physical; Nanoscience & Nanotechnology; Materials Science|

Authors: de Lara-Castells, Maria Pilar Journal: SMALL STRUCTURES Publication date: 2024/06/30 DOI: 10.1002/sstr.202400147 Abstract: Current advances in synthesizing and characterizing atomically precise monodisperse metal clusters (AMCs) at the subnanometer scale have opened up new possibilities in quantum materials research. Their quantizied molecule-like electronic structure showcases unique stability, and physical and chemical properties differentiate them from [...]

Temporal entropy and the complexity of computing the expectation value of local operators after a quench

Marcelo Castellanos2025-04-28T11:13:09+02:00Tags: Multidisciplinary. , Physics|

Authors: Carignano, Stefano; Marimon, Carlos Ramos; Tagliacozzo, Luca Journal: PHYSICAL REVIEW RESEARCH Publication date: 2024/07/03 DOI: 10.1103/PhysRevResearch.6.033021 Abstract: We study the computational complexity of simulating the time-dependent expectation value of a local operator in a one-dimensional quantum system by using temporal matrix product states(MPSs) and argue that it is intimately related to that of encoding [...]

Authors: Bartolomei, Massimiliano; Giorgi, Giacomo Journal: ACS MATERIALS LETTERS Publication date: 2024/09/12 DOI: 10.1021/acsmaterialslett.4c01119 Abstract: The bulk synthesis of gamma-graphyne has been recently achieved and evidenced a multilayered structure, which suggests its potential exploitation as a substitute of graphite-based anode materials for metals heavier than lithium (Li). In fact, each of its regular pores of [...]
