Holomorphic field theories and higher algebra

open access: yesBulletin of the London Mathematical Society, EarlyView.
Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

FRACTIONAL SUPERSYMMETRY [PDF]

open access: yesModern Physics Letters A, 1995
A symmetry between bosonic coordinates and some Grassmannian-type coordinates is presented. Commuting two of these Grassmannian-type variables results in an arbitrary phase factor (not just a minus sign). This symmetry is also realized at the level of the field theory.

The Nelson-Seiberg Theorem Generalized with Nonpolynomial Superpotentials

open access: yesAdvances in High Energy Physics, 2020
The Nelson-Seiberg theorem relates R-symmetries to F-term supersymmetry breaking and provides a guiding rule for new physics model building beyond the Standard Model.

Open-string models with broken supersymmetry

open access: yes, 2002
I review the salient features of three classes of open-string models with broken supersymmetry. These suffice to exhibit, in relatively simple settings, the two phenomena of ``brane supersymmetry'' and ``brane supersymmetry breaking''. In the first class

Enhancement of Dynamical Coupling in Artificial Spin‐Ice Systems by Incorporating Perpendicularly Magnetized Ferromagnetic Matrix

open access: yesSmall Structures, Volume 6, Issue 7, July 2025.
A new type of artificial spin ice (ASI) lattices, i.e., in the ASI system embedded in the perpendicular magnetic anisotropy (PMA) matrix, is proposed. The numerical simulations reveal a strong magnon–magnon coupling between the bulk second‐order mode of the ASI and the fundamental mode of the PMA matrix, supported by a pronounced anticrossing frequency

Natural heavy supersymmetry [PDF]

open access: yes, 2015
A bstractWe study how, as a result of the scanning of supersymmetry breaking during the cosmological evolution, a relaxation mechanism can naturally determine a hierarchy between the weak scale and the masses of supersymmetric particles.

Brane induced supersymmetry breaking and de Sitter supergravity [PDF]

open access: yesJournal of High Energy Physics, 2015
We obtain a four-dimensional supergravity with spontaneously broken super-symmetry allowing for de Sitter vacua by coupling a superspace action of minimal N = 1, D = 4 supergravity to a locally supersymmetric generalization of the Volkov-Akulov goldstino

Fractional supersymmetry as a superposition of ordinary supersymmetry [PDF]

open access: yesPhysics of Atomic Nuclei, 2005
It is shown how to derive fractional supersymmetric quantum mechanics of order k as a superposition of k-1 copies of ordinary supersymmetric quantum mechanics.

Fermi-Bose duality of the Dirac equation and extended real Clifford-Dirac algebra

open access: yesCondensed Matter Physics, 2010
We have proved on the basis of the symmetry analysis of the standard Dirac equation with nonzero mass that this equation may describe not only fermions of spin 1/2 but also bosons of spin 1.

Supersymmetry in quantum mechanics with point interactions [PDF]

open access: yes, 2003
We investigate supersymmetry in one-dimensional quantum mechanics with point interactions. We clarify a class of point interactions compatible with supersymmetry and present N=2 supersymmetric models on a circle with two point interactions as well as a ...
