Impulsive gravitational waves are theoretical models of short but violent bursts of gravitational radiation. They are commonly described by two distinct spacetime metrics, one of local Lipschitz regularity and the other one even distributio...

There are multiple conjectures relating the cohomological Hall algebras (CoHAs) of certain substacks of the moduli stack of representations of a quiver Q to the Yangian YMOQ by Maulik-Okounkov, whose construction is based on the notion of s...

We study superconformal indices of 4d compactifications of the 6d minimal (DN+3,DN+3) conformal matter theories on a punctured Riemann surface. Introduction of supersymmetric surface defect in these theories is done at the level of the inde...

We study the qualitative behaviour of the energy-momentum relation of the Fröhlich polaron at fixed coupling strength. Among other properties, we show that it is non-decreasing and that the correction to the quasi-particle energy is negati...

When a quantum field theory in d-spacetime dimensions possesses a global (d-1)-form symmetry, it can decompose into disjoint unions of other theories. This is reflected in the physical quantities of the theory and can be used to study prope...

We show that, for a class of planar determinantal point processes (DPP) X, the growth of the entanglement entropy S(X(Ω)) of X on a compact region Ω⊂R2d, is related to the variance VX(Ω) as follows: VX(Ω)≲SX(...

An extension of the notion of classical equivalence of equivalence in the Batalin-Vilkovisky (BV) and Batalin-Fradkin-Vilkovisky (BFV) frameworks for local Lagrangian field theory on manifolds possibly with boundary is discussed. Equivalenc...

We derive a number of spectral results for Dirac operators in geometrically nontrivial regions in R 2 and R 3 of tube or layer shapes with a zigzag-type boundary using the corresponding properties of the Dirichlet Laplacian. ...

On certain M-theory backgrounds which are a circle fibration over a smooth Calabi-Yau the quantum theory of M2 branes can be studied in terms of the K-theoretic Donaldson-Thomas theory on the threefold. We extend this relation to noncommuta...

We study the influence of an additional scalar potential on various geometric and analytic properties of Dirac-harmonic maps. We will create a mathematical wish list of the possible benefits from inducing the potential term and point out th...
