A novel approach for constructing kinetic energy operators with position dependent mass

Results in Physics, 2019
The interest in physical systems with position-dependent mass (PDM) is always topical. In this work we present a new way to construct kinetic energy operators (KEO’s) for particles endowed with a position varying mass within the Schrödinger equation ...

"Charge without Charge" in the Stochastic Interpretation of Quantum Mechanics [PDF]

, 2007
In this note I examine some implications of stochastic interpretations of quantum mechanics for the concept of "charge without charge" presented by Wheeler and Misner.

Miscellaneous Applications of Quons

Symmetry, Integrability and Geometry: Methods and Applications, 2007
This paper deals with quon algebras or deformed oscillator algebras, for which the deformation parameter is a root of unity. We show the interest of such algebras for fractional supersymmetric quantum mechanics, angular momentum theory and quantum ...

The giant graviton expansion in $AdS_5 \times S^5$

SciPost Physics
The superconformal index of $\frac12$-BPS states of $\mathcal{N}=4$ $U(N)$ super Yang-Mills theory has a known infinite $q$-series expression with successive terms suppressed by $q^N$.

Supersymmetric quantum mechanics on the lattice: I. Loop formulation

Nuclear Physics B, 2015
Simulations of supersymmetric field theories on the lattice with (spontaneously) broken supersymmetry suffer from a fermion sign problem related to the vanishing of the Witten index. We propose a novel approach which solves this problem in low dimensions

Supersymmetry and trace formulas. Part I. Compact Lie groups

Journal of High Energy Physics
In the context of supersymmetric quantum mechanics we formulate new supersymmetric localization principle, with application to trace formulas for a full thermal partition function.

Supersymmetric quantum mechanics on the lattice: II. Exact results

Nuclear Physics B, 2015
Simulations of supersymmetric field theories with spontaneously broken supersymmetry require in addition to the ultraviolet regularisation also an infrared one, due to the emergence of the massless Goldstino.

Quiver indices and Abelianization from Jeffrey-Kirwan residues

Journal of High Energy Physics, 2019
In quiver quantum mechanics with 4 supercharges, supersymmetric ground states are known to be in one-to-one correspondence with Dolbeault cohomology classes on the moduli space of stable quiver representations.

Supersymmetry Transformations for Delta Potentials

Symmetry, Integrability and Geometry: Methods and Applications, 2011
We make a detailed study of the first and second-order SUSY partners of a one-dimensional free Hamiltonian with a singular perturbation proportional to a Dirac delta function.

Multi-instantons and supersymmetric SU(N) gauge theories [PDF]

, 2002
In this thesis the proposed exact results for low energy effective N = 2 supersymmetric SU(N) Yang-Mills gauge theory coupled to Nf fundamental matter multiplets in four dimensions are considered.
