Exact renormalization group and Sine Gordon theory

open access: yesJournal of High Energy Physics, 2017
The exact renormalization group is used to study the RG flow of quantities in field theories. The basic idea is to write an evolution operator for the flow and evaluate it in perturbation theory.

The Green-Schwarz mechanism and geometric anomaly relations in 2d (0,2) F-theory vacua

open access: yesJournal of High Energy Physics, 2018
We study the structure of gauge and gravitational anomalies in 2d N = (0, 2) theories obtained by compactification of F-theory on elliptically fibered Calabi-Yau 5-folds. Abelian gauge anomalies, induced at 1-loop in perturbation theory, are cancelled by

Comments on the Atiyah-Patodi-Singer index theorem, domain wall, and Berry phase

open access: yesJournal of High Energy Physics, 2021
It is known that the Atiyah-Patodi-Singer index can be reformulated as the eta invariant of the Dirac operators with a domain wall mass which plays a key role in the anomaly inflow of the topological insulator with boundary.

The DNA of Calabi–Yau Hypersurfaces

open access: yesFortschritte der Physik, EarlyView.
Abstract Genetic Algorithms are implemented for triangulations of four‐dimensional reflexive polytopes, which induce Calabi–Yau threefold hypersurfaces via Batyrev's construction. These algorithms are shown to efficiently optimize physical observables such as axion decay constants or axion–photon couplings in string theory compactifications.

’t Hooft anomalies and the holomorphy of supersymmetric partition functions

open access: yesJournal of High Energy Physics, 2019
We study the dependence of supersymmetric partition functions on continuous parameters for the flavor symmetry group, G F , for 2d N $$ \mathcal{N} $$ = (0, 2) and 4d N $$ \mathcal{N} $$ = 1 supersymmetric quantum field theories.

The Measurement‐Impact Gap: A Bibliometric Diagnosis of Development Finance Institutions and SDG Research

open access: yesSustainable Development, EarlyView.
ABSTRACT The role of Development Finance Institutions (DFIs) in achieving the Sustainable Development Goals (SDGs) is a topic of growing scholarly importance. While existing literature has mapped the thematic scope of this field, a critical diagnosis of its intellectual structure and inherent biases is missing.

Non-supersymmetric duality cascade of QCD(BF) via semiclassics on ℝ2 × T 2 with the baryon-’t Hooft flux

open access: yesJournal of High Energy Physics
We study the phase diagrams of the bifundamental QCD (QCD(BF)) of different ranks, which is the 4d SU(N 1) × SU(N 2) gauge theory coupled with a bifundamental Dirac fermion. After discussing the anomaly constraints on possible vacuum structures, we apply
