Non-standard quantum algebra and -Dicke states

A. Ballesteros, J. J. Relancio, L. Santamaría-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, Lucía Santamaría-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. Santamaría-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. Santamaría-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. Santamaría-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…
