Supersymmetry-enhanced Stark-Chirped Rapid-Adiabatic-Passage in multimode optical waveguides

open access: yes, 2021
We propose a method to efficiently pump an excited mode of a multimode optical waveguide starting from a fundamental-mode input by combining Stark-Chirped Rapid Adiabatic Passage (SCRAP) and Supersymmetry (SUSY) transformations.

Missing energy signature for low scale supersymmetry breaking

open access: yesEPJ Web of Conferences, 2017
If the supersymmetry is broken at a scale about several TeVs particles from the sector responsible for the supersymmetry breaking - goldstino and sgoldstino - can reveal themselves already at the LHC experiments.

Dark Dimension With (Little) Strings Attached

open access: yesFortschritte der Physik, Volume 73, Issue 4, April 2025.
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

Moduli stabilization, de Sitter vacua and supersymmetry breaking [PDF]

open access: yes, 2016
We describe the phenomenology of a model of supersymmetry breaking in the presence of a tiny (tunable) positive cosmological constant. It utilises a single chiral multiplet with a gauged shift symmetry, that can be identified with the string dilaton (or ...

Supersymmetric Extension of Non-Hermitian su(2) Hamiltonian and Supercoherent States

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2010
A new class of non-Hermitian Hamiltonians with real spectrum, which are written as a real linear combination of su(2) generators in the form H=ωJ_3+αJ_−+βJ_+, α≠β, is analyzed.

Foundations of Ghost Stability

open access: yesFortschritte der Physik, Volume 73, Issue 4, April 2025.
Abstract The authors present a new method to analytically prove global stability in ghost‐ridden dynamical systems. The proposal encompasses all prior results and consequentially extends them. In particular, it is shown that stability can follow from a conserved quantity that is unbounded from below, contrary to expectation.

ASPECTS OF STRING PHENOMENOLOGY IN PARTICLE PHYSICS AND COSMOLOGY

open access: yesOdessa Astronomical Publications, 2016
We discuss possible connections between several scales in particle physics and cosmology, such the the electroweak, inflation, dark energy and Planck scales.

A Note on the Local Observability of Uniform Hypergraphs

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 25, Issue 1, March 2025.
ABSTRACT Hypergraphs generalize graphs in such a way that edges may connect any number of nodes. If all edges are adjacent to the same number of nodes, the hypergraph is called uniform. Thus, a graph is a 2‐uniform hypergraph. Each uniform hypergraph can be identified with an autonomous dynamical state‐space system, whose vector field is composed of ...

SUPERSYMMETRY OF PARAFERMIONS [PDF]

open access: yesModern Physics Letters A, 1999
We show that the single-mode parafermionic type systems possess supersymmetry, which is based on the symmetry of characteristic functions of the parafermions related to the generalized deformed oscillator of Daskaloyannis et al. The supersymmetry is realized in both unbroken and spontaneously broken phases.

Double Copy From Tensor Products of Metric BV■‐Algebras

open access: yesFortschritte der Physik, Volume 73, Issue 1-2, February 2025.
Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.
