Elementary particles with continuous spin

X Bekaert, ED Skvortsov - International Journal of Modern Physics …, 2017 - World Scientific
Classical results and recent developments on the theoretical description of elementary
particles with “continuous” spin are reviewed. At free level, these fields are described by …

Quantum Carroll/fracton particles

J Figueroa-O'Farrill, A Pérez, S Prohazka - Journal of High Energy Physics, 2023 - Springer
A bstract We classify and relate unitary irreducible representations (UIRs) of the Carroll and
dipole groups, ie, we define elementary quantum Carroll and fracton particles and establish …

Modular structure and inclusions of twisted Araki-Woods algebras

R Correa da Silva, G Lechner - Communications in Mathematical Physics, 2023 - Springer
In the general setting of twisted second quantization (including Bose/Fermi second
quantization, S-symmetric Fock spaces, and full Fock spaces from free probability as special …

Covariant homogeneous nets of standard subspaces

V Morinelli, KH Neeb - Communications in Mathematical Physics, 2021 - Springer
Rindler wedges are fundamental localization regions in AQFT. They are determined by the
one-parameter group of boost symmetries fixing the wedge. The algebraic canonical …

[HTML][HTML] From local nets to Euler elements

V Morinelli, KH Neeb - Advances in Mathematics, 2024 - Elsevier
Various aspects of the geometric setting of Algebraic Quantum Field Theory (AQFT) models
related to representations of the Poincaré group can be studied for general Lie groups …

Entropy of coherent excitations

R Longo - Letters in Mathematical Physics, 2019 - Springer
We provide a rigorous, explicit formula for the vacuum relative entropy of a coherent state on
wedge local von Neumann algebras associated with a free, neutral quantum field theory on …

The massless modular Hamiltonian

R Longo, G Morsella - Communications in Mathematical Physics, 2023 - Springer
We compute the vacuum local modular Hamiltonian associated with a space ball region in
the free scalar massless Quantum Field Theory. We give an explicit expression on the one …

Modular operator for null plane algebras in free fields

V Morinelli, Y Tanimoto, B Wegener - Communications in Mathematical …, 2022 - Springer
We consider the algebras generated by observables in quantum field theory localized in
regions in the null plane. For a scalar free field theory, we show that the one-particle …

Pauli-Lubanski limit and stress-energy tensor for infinite-spin fields

KH Rehren - Journal of High Energy Physics, 2017 - Springer
A bstract String-localized quantum fields transforming in Wigner's infinite-spin
representations were originally introduced in [18, 19]. We construct these fields as limits of …

A Bekenstein-type bound in QFT

R Longo - arxiv preprint arxiv:2409.14408, 2024 - arxiv.org
Let B be a spacetime region of width 2R> 0, and\phi a vector state localized in B. We show
that the vacuum relative entropy of\phi, on the local von Neumann algebra of B, is bounded …
