Ising the way into de Sitter
Giovanni Galati, Stathis Vitouladitis
The paper solves the two‑dimensional Ising model with a thermal deformation on de Sitter spacetime using fermionisation, computes exact cosmological correlators, and compares them…
Axions on de Sitter space
Vasileios A. Letsios, Stathis Vitouladitis
We study a massless minimally coupled compact scalar, or axion, on global -dimensional de Sitter space (dS). We quantise the theory canonically, determine the quantum dS cha…
The state/defect correspondence
Adrien Arbalestrier, Elise Paznokas, Stathis Vitouladitis
We formulate a one-to-one correspondence between states and defects for higher-form gauge theories in arbitrary dimensions. The correspondence is not predicated on conformal invari…
Higher-form entanglement asymmetry. Part I. The limits of symmetry breaking
Francesco Benini, Eduardo GarcÃa-Valdecasas, Stathis Vitouladitis
Entanglement asymmetry is a relative entropy that faithfully diagnoses symmetry breaking in quantum states, possibly within a spatial subregion. In this work, we extend such framew…
Higher-form anomalies and state-operator correspondence beyond conformal invariance
Stathis Vitouladitis
We establish a state-operator correspondence for a class of non-conformal quantum field theories with continuous higher-form symmetries and a mixed anomaly. Such systems can always…
Entanglement in BF theory I: Essential topological entanglement
Jackson R. Fliss, Stathis Vitouladitis
We study the entanglement structure of Abelian topological order described by -form BF theory in arbitrary dimensions. We do so directly in the low-energy topological quantum fi…
