The tt*-structure for the quantum cohomology of complex Grassmannian
The tt*-equation (topological-anti-topological fusion equation) was introduced by S. Cecotti and C. Vafa for describing massive deformation of supersymmetric conformal field theories. B. Dubrovin…

Twistor Wilson loops in large-N Yang-Mills theory
It has been known for many years that, in Yang-Mills theories with N=4,2,2* supersymmetry, certain nontrivial supersymmetric Wilson loops exist with v.e.v. either trivial or computable…

Tracking discontinuities in parameter space
We develop a geometric framework in Feynman-parameter space to determine constraints on the sequential discontinuities of Feynman integrals. Our method is based on tracking the deformation of the…

Open case for a closed universe
We establish a new no-go theorem for cosmology: spatially flat (k=0) and open (k=-1) Friedmann--Robertson--Walker (FRW) non-static spacetimes cannot be simultaneously nonsingular, geodesically…

Diffeomorphism invariant tensor networks for 3d gravity
Tensor networks prepare states that share many features of states in quantum gravity. However, standard constructions are not diffeomorphism invariant and do not support an algebra of non-commuting…

On the Imaginary Part of the Effective Action in de Sitter Spacetime with Different Regularization Schemes
The imaginary part of the effective action encodes vacuum instability and particle production in the background field. Two standard approaches are commonly used to derive it: the Bogoliubov method…

Four-charge static non-extremal black holes in the five-dimensional N=2, STU-W2U supergravity
We construct, for the first time, new static non-extremal five-dimensional black hole solutions (without or with squashed horizons) endowing with four different electric charge parameters in the $D =…

Logarithmic Corrections to Thermodynamics of Accelerating Black Holes
As pointed out in recent research, the near extremal black hole entropy with one-loop effect exhibits universal T behavior at sufficiently low temperature. In this paper, we discuss the…

Chiral Quartic Massive Gravity in Three Dimensions
We study New Massive Gravity (NMG) with Chern-Simons (CS), cubic, and quartic terms under the Compère-Song-Strominger (CSS) boundary conditions. By employing a semi-product of a Virasoro and a U(1)…

Shadow sectors of gauge theories
We show that both abelian and non-abelian gauge theories admit configurations in which the fields behave as if in the presence of static charge densities, or ``shadow charges". These correspond…

De Sitter holographic complexity from Krylov complexity in DSSYK
We utilize the recent connection between the high energy limit of the double-scaled SYK model and two-dimensional de Sitter solutions of sine dilaton gravity to identify the length of a family of…

Subdimensional Disorder and Logarithmic Defect
We study quenched disorder localized on a p-dimensional subspacetime in a d-dimensional conformal field theory. Motivated by the logarithmic behavior often associated with disorder, we introduce…

Axion-Scalar Systems and Dynamical Distances
We study the cosmology of axion-scalar pairs, coupled by a hyperbolic field-space metric and with a string-motivated rational scalar potential. Borrowing tools from the theory of dynamical systems,…

Branes and Antibranes in AdS3: The Impossible States in the CFT Gap

Classification and Birational Equivalence of Dimer Integrable Systems for Reflexive Polygons
