Deformed Conformal and Supersymmetric Quantum Mechanics
Within the standard quantum mechanics a q-deformation of the simplest N = 2 supersymmetry algebra is suggested. Resulting physical systems do not have conserved charges and degeneracies in the spectra. Instead, superpartner Hamiltonians are q-isospectral, i.e. the spectrum of one can be obtained from another (with possible exception of the lowest level) by the q2-factor scaling. A special class...
متن کاملGauging N =4 Supersymmetric Mechanics
We argue that off-shell dualities between d=1 supermultiplets with different sets of physical bosonic components and the same number of fermionic ones are related to gauging some symmetries in the actions of the supermultiplets with maximal sets of physical bosons. Our gauging procedure uses off-shell superfields and so is manifestly supersym-metric. We focus on N =4 supersymmetric mechanics an...
متن کاملN = 4 Supersymmetric Mechanics in Harmonic Superspace
We define N =4, d=1 harmonic superspace HR 1+2|4 with an SU(2)/U(1) harmonic part, SU(2) being one of two factors of the R-symmetry group SU(2)× SU(2) of N =4, d=1 Poincaré supersymmetry. We reformulate, in this new setting, the models of N =4 supersymmetric quantum mechanics associated with the off-shell mul-tiplets (3, 4, 1) and (4, 4, 0). The latter admit a natural description as constrained...
متن کاملDeformed matrix models , supersymmetric lattice twists and N = 14 supersymmetry
A manifestly supersymmetric nonperturbative matrix regularization for a twisted version of N = (8, 8) theory on a curved background (a two-sphere) is constructed. Both continuum and the matrix regularization respect four exact scalar supersymmetries under a twisted version of the supersymmetry algebra. We then discuss a succinct Q = 1 deformed matrix model regularization ofN = 4 SYM in d = 4, w...
متن کاملHarmonic Superfields in N = 4 Supersymmetric Quantum Mechanics
This is a brief survey of applications of the harmonic superspace methods to the models of N = 4 supersymmetric quantum mechanics (SQM). The main focus is on a recent progress in constructing SQM models with couplings to the background non-Abelian gauge fields. Besides reviewing and systemizing the relevant results, we present some new examples and make clarifying comments.
