Ultraviolet Completion of the Big Bang in Quadratic Gravity
We present a quantum quadratic gravity inflationary scenario that can accommodate the new cosmological constraints, which have disfavored Starobinsky inflation. The theory is asymptotically free in…

Time-dependent black hole lensing from ringdown quasinormal mode
Is it possible to find imprints of a black hole ringdown through gravitational lensing? To address this question, we formulate an analytic description of weak-field and strong-deflection lensing of…

Large N Universality of 4d N=1 SCFTs with Simple Gauge Groups
We classify four-dimensional N=1 supersymmetric gauge theories with a simple gauge group admitting a large N limit that flow to non-trivial superconformal fixed points in the infrared.…

Noncommutative Gauge Theories: Yang-Mills extensions and beyond - An overview
The status of several representative gauge theories on various quantum space-times, mainly focusing on Yang-Mills type extensions together with a few matrix model formulations is overviewed. The…

Towards a Quintic Ginzburg-Landau Description of the (2,7) Minimal Model
We discuss dimensional continuation of the massless scalar field theory with the iϕ5 interaction term. It preserves the so-called PT symmetry, which acts by ϕ→ -ϕ…

Lieb-Robinson causality and non-Fermi liquids
Quantum mechanical lattice models with local, bounded interactions obey Lieb-Robinson causality. We show that this implies a domain of analyticity of the retarded Green's function $GR(ω,…

Semiclassical cosmic string evaporation
We describe a new tunneling solution for the decay of a cosmic string into a burst of gravitational waves. We find the relevant instanton and compute the tunneling rate. Locally, our solution is just…

Frozen Firewall: Generic Singularity Formation on an Extremal Horizon
It is known that linearized perturbations of extremal black holes result in growing curvature on the horizon. However, nonlinear perturbations typically do not evolve to extremal black holes and do…

de Sitter no-go's for Riemann-flat manifolds and a link to semidefinite optimisation
We establish a no-go theorem in the context of string and M-theory flux compactifications on Riemann-Flat manifolds with Casimir energy. Specifically, we show that no dS minimum exists in this setup…

Covariant field theory of 3D massive fractons
We construct a covariant and gauge-invariant theory describing massive fractons in three spacetime dimensions, based on a symmetric rank-2 tensor field. The model includes a Chern-Simons-like term…

Towards a unified viewpoint of Gribov--Zwanziger and Serreau--Tissier gauge fixing
We investigate a unified Landau--gauge fixing that continuously interpolates between the viewpoints of the Serreau--Tissier (ST) copy-averaged formulation and the (Refined) Gribov--Zwanziger (RGZ)…

Multi-entropy from Linking in Chern-Simons Theory

Multi-Instantons, Multi-Axions, and Non-Invertible Symmetries in 4d QFT
We study non-invertible global symmetries in 4d quantum field theories, aiming to generalize existing discussions to theories with multiple instantons and axions, and to make the subject more…

A spin on Hagedorn temperatures and string stars
We discuss the correspondence between highly excited strings and black holes in the presence of angular momentum. At fixed imaginary angular velocity ν, we show that free strings exhibit a Hagedorn…

Matrix Correlators as Discrete Volumes of Moduli Space I: Recursion Relations, the BMN-limit and DSSYK
We show certain correlators in generic one-matrix models define a notion of ``discrete'' volumes of the moduli space of Riemann surfaces, generalizing the connection between random matrices…

Equivalence of first and second order formulations of the Einstein-Hilbert theory

The Spectrum-generating Algebra for Bosonic Strings in a Linear Dilaton Background

Classical limit of a scalar quantum field theory
