Effects of θ in supersymmetric theories
Abstract Possible effects of introduction of the “θ-parameter” into supersymmetric theories are investigated on the basis of a 1/ N expansion. It is found that, in a two-dimensional SU( N )-symmetric U(1) gauge theory without chiral symmetry, supersymmetry remains unbroken in the presence of the θ-term although physical quantities depend on θ and ...

Modeling General Asymptotic Calabi–Yau Periods
Abstract In the quest to uncovering the fundamental structures that underlie some of the asymptotic Swampland conjectures the authors initiate the general study of asymptotic period vectors of Calabi–Yau manifolds. The strategy is to exploit the constraints imposed by completeness, symmetry, and positivity, which are formalized in asymptotic Hodge ...

Programmable photonic unitary circuits for light computing
Abstract Unitarity serves as a fundamental concept for characterizing linear and conservative wave phenomena in both classical and quantum systems. Developing platforms that perform unitary operations on light waves in a universal and programmable manner enables the emulation of complex light–matter interactions and the execution of general‐purpose ...

Two-loop anomalous dimensions for four-Fermi operators in supersymmetric theories
We derive two-loop anomalous dimensions for four-Fermi operators in supersymmetric theories using the effective Kähler potential. We introduce the general forms in generic gauge theories and apply our results to the flavor-changing operators in (minimal)

The twisted index and topological saddles
The twisted index of 3d N $$ \mathcal{N} $$ = 2 gauge theories on S 1 × Σ has an algebro-geometric interpretation as the Witten index of an effective supersymmetric quantum mechanics.

Dark Dimension With (Little) Strings Attached
Abstract A relation between dark energy and the scale of new physics in weakly coupled string theory is motivated. This mixing between infrared and ultraviolet physics leads to a unique corner for real‐world phenomenology: barring fine‐tunings, the authors are naturally led to the “dark dimension” scenario, a single mesoscopic extra dimension of micron

The action of long strings in supersymmetric field theories
Long strings emerge in many Quantum Field Theories, for example as vortices in Abelian Higgs theories, or flux tubes in Yang-Mills theories. The actions of such objects can be expanded in the number of derivatives, around a long straight string solution.
