Thermodynamic and observational implications of black holes in toroidal geometry
We investigate the thermodynamic and observational implications for the charged torus-like black holes, a class of solutions distinct from the classical Schwarzschild black holes. We explicitly…

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the string-theoretical Swampland Programme
String theory has strong implications for cosmology: it tells us that we cannot have a cosmological constant, that single-field slow-roll inflation is ruled out, and that black holes decay. We…

A double copy from twisted (co)homology at genus g
We study a family of generalized hypergeometric integrals defined on punctured Riemann surfaces of genus g. These integrals are closely related to g-loop string amplitudes in chiral splitting, where…

Bosonic Bogoliubov transformations as Lorentz boosts in (c, c)=(1,1) conformal field theories with marginal J J deformations
We consider conformal field theories with central charges (c, c)=(1,1) that are invariant under the exchange of the holomorphic and antiholomorphic sectors, in both bosonic and fermionic…

On symmetry breaking in the self-dual higher-spin theory
We explore the symmetry-broken phase of the self-dual (chiral) sector of higher-spin theory in four dimensions. To that end, we construct a two-parameter vacuum that breaks the AdS symmetry but…

Flat Space Holography via AdS/BCFT
In this paper, we study a new class of AdS/BCFT setups, where the world-volumes of end-of-the-world branes (EOW branes) are given by flat spaces, to explore flat space holography from an AdS bulk. We…

Dissipation suppression for an Unruh-DeWitt battery with a reflecting boundary
In the framework of open quantum systems, we study the dynamics of an accelerated quantum battery (QB), modeled as an Unruh-DeWitt detector interacting with a real massless scalar quantum field. The…

Vacuum currents in elliptic pseudosphere tubes
We examine the effects of spatial topology, curvature, and magnetic flux on the vacuum expectation value (VEV) of the current density for a charged scalar field in (2+1)-dimensional spacetime. The…

Quantum-group-invariant D(2)n+1 models: Bethe ansatz and finite-size spectrum

Genuine multientropy, dihedral invariants and Lifshitz theory
Multi-invariants are local-unitary invariants of state replicas introduced as potential probes of multipartite entanglement and correlations in quantum many-body systems. In this paper, we…

Mass-deformed Super Yang-Mills theory on T4: sum over twisted sectors, θ-angle, and CP violation

A new characterization of the holographic entropy cone
Entanglement entropies computed using the holographic Ryu-Takayanagi formula are known to obey an infinite set of linear inequalities, which define the so-called RT entropy cone. The general…
