Polyadic Supersymmetry

open access: yesUniverse
We introduce a polyadic analog of supersymmetry by considering the polyadization procedure (proposed by the author) applied to the toy model of one-dimensional supersymmetric quantum mechanics. The supercharges are generalized to polyadic ones using the n-ary sigma matrices defined in earlier work.

Resolutions of Identity for Some Non-Hermitian Hamiltonians. I. Exceptional Point in Continuous Spectrum

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2011
Resolutions of identity for certain non-Hermitian Hamiltonians constructed from biorthogonal sets of their eigen- and associated functions are given for the spectral problem defined on entire axis.

QCD and Supersymmetry

open access: yesCrossing the Boundaries, 2009
We review the connection between QCD and supersymmetric theories. We focus on the non-perturbative large- N (planar) correspondence between one-flavor QCD and pure supersymmetric Yang-Mills theory ([Formula: see text]). We explain how non-perturbative quantities in QCD, such as the quark condensate, can be evaluated by using the corresponding non ...

A Generic Analysis of Nucleon Decay Branching Fractions in Flipped SU(5) Grand Unification

open access: yesUniverse
In flipped SU(5) grand unified theories, the partial decay lifetimes of certain nucleon decay channels depend generically on an unknown unitary matrix, which arises when left-handed lepton fields are embedded into anti-fundamental representations of SU(5)

Topological quantum pump of strongly interacting fermions in coupled chains

open access: yesNew Journal of Physics, 2019
We analyse a tight binding model of two coupled chains with strongly interacting fermions. Depending on the parameter w , the many body lowest energy band consists of either single particles or bound pairs.
