BFT2: a general class of 2d N $$ \mathcal{N} $$ = (0, 2) theories, 3-manifolds and toric geometry

Journal of High Energy Physics, 2022
We introduce and initiate the study of a general class of 2d N $$ \mathcal{N} $$ = (0, 2) quiver gauge theories, defined in terms of certain 2-dimensional CW complexes on oriented 3-manifolds. We refer to this class of theories as BFT2’s.

Tessellation Groups, Harmonic Analysis on Non‐Compact Symmetric Spaces and the Heat Kernel in View of Cartan Convolutional Neural networks

Fortschritte der Physik, Volume 74, Issue 4, April 2026.
ABSTRACT In this paper, we continue the development of the Cartan neural networks programme, launched with three previous publications, by focusing on some mathematical foundational aspects that we deem necessary for our next steps forward. The mathematical and conceptual results are diverse and span various mathematical fields, but the inspiring ...

Monopoles, Clarified

Fortschritte der Physik, Volume 74, Issue 3, March 2026.
ABSTRACT We propose a manifestly duality‐invariant, Lorentz‐invariant, and local action to describe quantum electrodynamics in the presence of magnetic monopoles that derives from Sen's formalism. By employing field strengths as the dynamical variables, rather than potentials, this formalism resolves longstanding ambiguities in prior frameworks.

Initial Distance‐Dependent Mean Force Drives Synaptic Vesicle Motion Toward Fusion Sites in Stimulated Hippocampal Neurons

Advanced Science, Volume 13, Issue 12, 27 February 2026.
Synaptic vesicle (SV) motion and exocytosis dynamics in the presynaptic terminals of live neurons are intimately linked to synaptic transmission during neuronal activity. In this work, it is revealed that, during electrical stimulation, SVs located farther from their fusion sites exhibit greater straightness and experience larger mean forces directed ...

End of the world boundaries for chiral quantum gravity theories

Journal of High Energy Physics
We describe the construction of large classes of explicit string theory backgrounds corresponding to 6d and 4d chiral theories with end of the world boundaries, and describe the strong coupling phenomena involved in gapping the chiral (but non-anomalous)

Brane webs and magnetic quivers for SQCD

Journal of High Energy Physics, 2020
It is widely considered that the classical Higgs branch of 4d N $$ \mathcal{N} $$ = 2 SQCD is a well understood object. However there is no satisfactory understanding of its structure.

M2-branes and plane partitions

Journal of High Energy Physics, 2022
There is a correspondence between the protected local operators in the 3d SCFTs describing the geometry ℂ2 probed by a stack of N M2-branes and plane partitions of trace N.

Deparametrization of General Relativity by Space‐Time Filling Unstable D9‐Brane With Arbitrary Value of Tachyon

Advances in High Energy Physics, Volume 2026, Issue 1, 2026.
We calculate the algebra of constraints for deparametrized general relativity with a space‐time filling unstable D‐brane for an arbitrary value of tachyon field T. We also propose observables that have vanishing Poisson brackets with all first‐class constraints.

Compactness of brane moduli and the String Lamppost Principle in d > 6

Journal of High Energy Physics, 2022
We demonstrate the validity of the String Lamppost Principle — that all consistent theories of quantum gravity are in the String Landscape — for supersymmetric theories in d > 6 using compactness and connectedness of the moduli space of small instantons,

Comments on the RG‐Flow in Open String Field Theory

Fortschritte der Physik, Volume 73, Issue 12, December 2025.
Abstract We define a metric G$G$ on the KBc‐subalgebra modulo gauge and describe the worldsheet RG‐flow as the gradient flow of the action of cubic open string field theory, where the flow lines are kink‐solitons. In particular, for a constant tachyon the gradient flow equations are equivalent to the RG‐equations. Additionally, a more general family of
