Holography for BCFTs with Multiple Boundaries: Multi-Splitting Quenches

Joseph Lap, Berndt Mueller, Andreas Schaefer +1

We elaborate on the method introduced in arXiv:2403.02165 for holographic duals of Boundary Conformal Field Theories (BCFTs) with multiple boundaries. Using these advances we calcu…

Visions in Quantum Gravity

Luca Buoninfante, Benjamin Knorr, K. Sravan Kumar +36

To deepen our understanding of Quantum Gravity and its connections with black holes and cosmology, building a common language and exchanging ideas across different approaches is cr…

Dynamical edge modes in Maxwell theory from a BRST perspective, with an application to the Casimir energy

Fabrizio Canfora, David Dudal, Thomas Oosthuyse +2

Recently, dynamical edge modes (DEM) in Maxwell theory have been constructed using a specific local boundary condition on the horizon. We discuss how to enforce this boundary condi…

Holographic (Eternal) Inflation

Thomas Hertog, Jef Pauwels, Victoria Venken

We identify a minisuperspace of complex deformations of ABJM theory for which the partition function specifies the amplitude of an eternally inflating universe. The boundary theory…

Interplay of magnetic field and chemical potential induced anisotropy and frame dependent chaos of a pair in holographic QCD

Bhaskar Shukla, Jasper Nongmaithem, David Dudal +1

We investigate the role of both magnetic field and chemical potential on the emergence of chaotic dynamics in the QCD confining string from the holographic principle. An earlier de…

Non-analytic terms of string amplitudes from partial waves

Yu-tin Huang, Hynek Paul, Michele Santagata

We describe a general formalism based on the partial-wave decomposition to compute the iterative -channel discontinuity of four-point amplitudes at any loop order. As an applica…

Interplay between the Lyapunov exponents and phase transitions of charged AdS black holes

Bhaskar Shukla, Pranaya Pratik Das, David Dudal +1

We study the relationship between the standard or extended thermodynamic phase structure of various AdS black holes and the Lyapunov exponents associated with the null and time-lik…

de Sitter at all loops: the story of the Schwinger model

Dionysios Anninos, Tarek Anous, Alan Rios Fukelman

We consider the two-dimensional Schwinger model of a massless charged fermion coupled to an Abelian gauge field on a fixed de Sitter background. The theory admits an exact solution…

Dynamically massive linear covariant gauges: setup and first results

Giorgio Comitini, Tim De Meerleer, David Dudal +1

We discuss the possibility to obtain a massive Landau gauge, based on the local composite operator (LCO) effective action framework combined with the Zimmerman reduction of couplin…
