Perfectly invisible PT $$ \mathcal{P}\mathcal{T} $$ -symmetric zero-gap systems, conformal field theoretical kinks, and exotic nonlinear supersymmetry [PDF]
We investigate a special class of the PT $$ \mathcal{P}\mathcal{T} $$ -symmetric quantum models being perfectly invisible zero-gap systems with a unique bound state at the very edge of continuous spectrum of scattering states. The family includes the PT $

Fermionic coordinates and supersymmetry in quantum mechanics [PDF]
Abstract We describe the quantum mechanics of particles with fermionic degrees of freedom, both in the Schrodinger wave function and Feynman path integral formalism. In particular we derive an exact expression for fermionic path integrals in (0 + 1) dimensions. Under suitable circumstances the theories we consider can exhibit supersymmetry.

Bosonized supersymmetric quantum mechanics and supersymmetry of parabosons (parafermions) [PDF]
We review the construction of minimally bosonized supersymmetric quantum mechanics and its relation to hidden supersymmetries in pure parabosonic (parafermionic) systems.

Quantum Mechanics in Grassmann Space, Supersymmetry and Gravity [PDF]
A particle which lives in a d-dimensional ordinary and a d-dimensional Grassmann space manifests itself in an ordinary four-dimensional subspace as a spinor, a scalar or a vector with charges. Operators of the Lorentz transformations and translations in both spaces form the super- Poincar\' e algebra.

N=2 double graded supersymmetric quantum mechanics via dimensional reduction [PDF]
We presented a novel $ \mathcal{N} = 2 $ $ \mathbb{Z}_2^2 $-graded supersymmetric quantum mechanics ($ {\mathbb{Z}_2^2} $-SQM) which has different features from those introduced so far.

Hidden Symmetry from Supersymmetry in One-Dimensional Quantum Mechanics [PDF]
When several inequivalent supercharges form a closed superalgebra in Quantum Mechanics it entails the appearance of hidden symmetries of a Super-Hamiltonian. We examine this problem in one-dimensional QM for the case of periodic potentials and potentials

Supersymmetry shielding the scaling symmetry of conformal quantum mechanics [PDF]
Renormalization of the inverse square potential usually breaks its classical conformal invariance. In a strongly attractive potential, the scaling symmetry is broken to a discrete subgroup while, in a strongly repulsive potential, it is preserved at ...

Quantum Mechanics à la Langevin and Supersymmetry [PDF]
We study quantum mechanics in the stochastic formulation, using the functional integral approach. The noise term enters the classical action as a local contribution of anticommuting fields. The partition function is not invariant under ${\mathcal N}=1$ SUSY, but can be obtained from a, manifestly, supersymmetric expression, upon fixing a local ...
