Quantum deformations of . Part I: Fidelity and experimental benchmarking
V. Mariscal, J. J. Relancio, L. SantamarÃa-Sanz
This work explores the effects of both the standard quantum -deformation and the non-standard -deformation of the Hopf algebra on…
Non-standard quantum algebra and -Dicke states
A. Ballesteros, J. J. Relancio, L. SantamarÃa-Sanz
We discuss the application of the Jordanian quantum algebra , a Hopf algebra deformation of the Lie algebra $\mathfrak{sl}(2, \mathbb{…
Symmetry Resolved Entanglement with Symmetry: Some Closed Formulae for Excited States
Olalla A. Castro-Alvaredo, LucÃa SantamarÃa-Sanz
In this work, we revisit a problem we addressed in previous publications with various collaborators, that is, the computation of the symmetry resolved entanglement entropies of zer…
Doubly special relativity as a non-local quantum field theory
J. J. Relancio, L. SantamarÃa-Sanz
In this work, we explore the quantum theories of the free massive scalar, the massive fermionic, and the electromagnetic fields, in a doubly special relativity scenario. This const…
Non-local quantum field theory from doubly special relativity
J. J. Relancio, L. SantamarÃa-Sanz
Doubly special relativity (DSR) is usually regarded as a low-energy limit of a quantum gravity theory with testable predictions. On the other hand, non-local quantum field theories…
Generalized Hamilton spaces: new developments and applications
J. J. Relancio, L. SantamarÃa-Sanz
In this work, we make new developments in generic cotangent bundle geometries, depending on all phase-space variables. In particular, we will focus on the so-called generalized Ham…
