Pauli weight requirement of the matrix elements in time-evolved local operators: Dependence beyond the equilibration temperature

Marcelo Castellanos2025-04-29T11:13:15+02:00Tags: Applied; Physics, Condensed Matter. , Materials Science, Multidisciplinary; Physics|

Authors: Ramos-Marimon, Carlos; Carignano, Stefano; Tagliacozzo, Luca Journal: PHYSICAL REVIEW B Publication date: 2025/03/05 DOI: 10.1103/PhysRevB.111.094301 Abstract: The complexity of simulating the out-of-equilibrium evolution of local operators in the Heisenberg picture is governed by the operator entanglement, which grows linearly in time for generic nonintegrable systems, leading to an exponential increase in computational resources. A [...]

Majorana bound states from cavity embedding in an interacting two-site Kitaev chain

Authors: Gomez-Leon, Alvaro; Schiro, Marco; Dmytruk, Olesia Journal: PHYSICAL REVIEW B Publication date: 2025/04/09 DOI: 10.1103/PhysRevB.111.155410 Abstract: Poor man's Majorana bound states (MBS) arise in minimal Kitaev chains when the parameters are fine-tuned to a sweet spot. We consider an interacting two-site Kitaev chain coupled to a single-mode cavity and show that the sweet spot [...]

Linear response theory for cavity QED materials at arbitrary light-matter coupling strengths

Authors: Roman-Roche, Juan; Gomez-Leon, Alvaro; Luis, Fernando; Zueco, David Journal: PHYSICAL REVIEW B Publication date: 2025/01/31 DOI: 10.1103/PhysRevB.111.035156 Abstract: We develop a linear response theory for materials collectively coupled to a cavity that is valid in all regimes of light-matter coupling, including symmetry-broken phases. We present and compare two different approaches. First, we use a [...]

Gapless deconfined phase in a Z N-symmetric Hamiltonian created in a cold-atom setup

Authors: Rakov, Mykhailo, V; Tagliacozzo, Luca; Lewenstein, Maciej; Zakrzewski, Jakub; Chanda, Titas Journal: PHYSICAL REVIEW B Publication date: 2024/11/05 DOI: 10.1103/PhysRevB.110.195114 Abstract: We investigate a quasi-two-dimensional system consisting of two species of alkali atoms confined in a specific optical lattice potential [Phys. Rev. A 95 , 053608 (2017)]. In the low-energy regime, this system is [...]

Spectral properties of the critical (1+1)-dimensional Abelian-Higgs model

Marcelo Castellanos2025-04-28T11:13:16+02:00Tags: Applied; Physics, Condensed Matter. , Materials Science, Multidisciplinary; Physics|

Authors: Chanda, Titas; Dalmonte, Marcello; Lewenstein, Maciej; Zakrzewski, Jakub; Tagliacozzo, Luca Journal: PHYSICAL REVIEW B Publication date: 2024/01/02 DOI: 10.1103/PhysRevB.109.045103 Abstract: The presence of gauge symmetry in 1+1 dimensions is known to be redundant, since it does not imply the existence of dynamical gauge bosons. As a consequence, in the continuum, the Abelian -Higgs model [...]

Sodium into ?-Graphyne Multilayers: An Intercalation Compound for Anodes in Metal-Ion Batteries

Marcelo Castellanos2025-04-28T11:13:01+02:00Tags: Materials Science, Multidisciplinary. |

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 [...]

Quenches to the critical point of the three-state Potts model: Matrix product state simulations and conformal field theory

Marcelo Castellanos2023-02-21T13:36:56+01:00Tags: Applied; Physics, Condensed Matter. , Materials Science, Multidisciplinary; Physics|

Authors: Robertson, Niall F.; Surace, Jacopo; Tagliacozzo, Luca Journal: PHYSICAL REVIEW B Publication date: 2022/05/04 DOI: 10.1103/PhysRevB.105.195103 Abstract: Conformal field theories (CFTs) have been used extensively to understand the physics of critical lattice models at equilibrium. However, the applicability of CFT calculations to the behavior of the lattice systems in the out-of-equilibrium setting is not [...]

Role of boundary conditions in the full counting statistics of topological defects after crossing a continuous phase transition

Marcelo Castellanos2023-02-21T13:36:21+01:00Tags: Applied; Physics, Condensed Matter. , Materials Science, Multidisciplinary; Physics|

Authors: Gomez-Ruiz, Fernando J.; Subires, David; del Campo, Adolfo Journal: PHYSICAL REVIEW B Publication date: 2022/10/10 DOI: 10.1103/PhysRevB.106.134302 Abstract: In a scenario of spontaneous symmetry breaking in finite time, topological defects are generated at a density that scales with the driving time according to the Kibble-Zurek mechanism (KZM). Signatures of universality beyond the KZM have [...]
