Massless S-matrix Bootstraps and RG Flows
We find complete solutions of S-matrix bootstrap equations for the scatterings of massless particles in (1+1) dimensions with An symmetries. We show that only three types (minimal, diagonal, and…

Higher structure of non-invertible symmetries from Lagrangian descriptions
The symmetry structure of a quantum field theory is determined not only by the topological defects that implement the symmetry and their fusion rules, but also by the topological networks they can…

Charged Black-Hole Binary Evolution at Second Post-Newtonian Order
We study the dynamics of electrically charged black-hole binaries and their gravitational-wave emission during the inspiral phase. Within the post-Newtonian framework, we derive the conservative and…

Chronology Protection of Rotating Black Holes in a Viable Lorentz-Violating Gravity
We study causal properties of the recently found rotating black-hole solution in the low-energy sector of Horava gravity as a viable Lorentz-violating (LV) gravity in four dimensions with the LV…

Causal perturbation theory and scattering amplitudes
Motivated by the limited interaction between the mathematical physics community and theoretical physicists - particularly in high-energy theory - we present a computation that is typically the first…

Non-linear sigma model in string field theory
We revisit the non-linear sigma model approach to string theory with the closed superstring field theory. We construct the string field theory around the non-linear sigma model background with the…

Freelance Holography
In this paper, we introduce the Freelance Holography Program, an extension of the AdS/CFT correspondence within the saddle-point approximation that opens several novel directions. This framework…

Scalar Amplitudes from Fibre Bundle Geometry
We compute tree-level n-point scattering amplitudes in scalar field theories in terms of geometric invariants on a fibre bundle. All 0- and 2-derivative interactions are incorporated into a metric…

Supergroup Invariants and the Brane/Negative Brane Expansion
We propose a Molien--Weyl-type formula computing generating functions of invariants of supergroups U(N|M), i.e. polynomials in supertraces, which arise as gauge groups of brane/negative brane…

Geometric Building Blocks of Effective Field Theory Amplitudes
On-shell amplitudes are invariant under field redefinitions. Nonderivative field redefinitions have a natural interpretation as coordinate transformations on the target manifold. General field…

Mind the crosscap: τ-scaling in non-orientable gravity and time-reversal-invariant systems
Spectral statistics of quantum chaotic systems are governed by random matrix universality. In many cases of interest, time-reversal symmetry selects the Gaussian Orthogonal Ensemble (GOE) as the…

Non-renormalisation of coupling constants from categorical symmetries in two dimensions
We study the role of categorical symmetries in constraining the renormalisation of couplings in two-dimensional non-linear sigma models with Wess-Zumino term. A large class of these theories admit…

Exact non-Lagrangian Schur index in closed form
The Schur index is a powerful tool to probe the spectrum and dualities of 4d N=2 superconformal field theories (SCFTs), deeply related to 2d vertex operator algebras (VOAs). In this…

Universality in the resurgence of generalized Tracy-Widom distributions

Aspects of non-minimally coupled curvature with power laws
We consider a class of theories containing power-law terms in both the Ricci scalar and a scalar field, including their non-minimal couplings. As a first step, we systematically classify all…

Schwinger effect in dynamical holographic QCD with a supercritical region

Higher-Spin Poisson Sigma Models and Holographic Duality for SYK Models
