Hidden symmetry and (super)conformal mechanics in a monopole background
Journal of High Energy Physics, 2020 We study classical and quantum hidden symmetries of a particle with electric charge e in the background of a Dirac monopole of magnetic charge g subjected to an additional central potential V (r) = U (r) + (eg)2 /2mr 2 with U (r) = 1 2 $$ \frac{1}{2 ...

Localization and duality for ABJM latitude Wilson loops
Journal of High Energy Physics, 2021 We investigate several aspects of BPS latitude Wilson loops in gauge theories in three dimensions with N $$ \mathcal{N} $$ ≥ 4 supersymmetry. We derive a matrix model for the bosonic latitude Wilson loop in ABJM using supersymmetric localization, and ...

The 3d twisted index and wall-crossing
SciPost Physics, 2022 We study the twisted index of 3d $\mathcal{N}=2$ supersymmetric gauge theories on $S^1 \times \Sigma$ in the presence of a real FI parameter deformation. This parameter induces a 1d FI parameter for the effective supersymmetric quantum mechanics on $S^1$.

Supersymmetry and the Spontaneous Breakdown of PT Symmetry [PDF]
, 2001 The appearances of complex eigenvalues in the spectra of PT-symmetric quantum mechanical systems are usually associated with a spontaneous breaking of PT.

On supersymmetries in nonrelativistic quantum mechanics [PDF]
Journal of Mathematical Physics, 1992 One-dimensional nonrelativistic systems are studied when time-independent potential interactions are involved. Their supersymmetries are determined and their closed subsets generating kinematical invariance Lie superalgebras are pointed out. The study of even supersymmetries is particularly enlightened through the already known symmetries of the ...

Journal of High Energy Physics, 2017 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 $

Lattice study of supersymmetry breaking in N=2 supersymmetric quantum mechanics
Nuclear Physics B, 2019 We study supersymmetry breaking from a lattice model of N=2 supersymmetric quantum mechanics using a direct computational method proposed in arXiv:1803.07960. The vanishing Witten index is realized as a numerical result in high precision. The expectation

Quantum-mechanical supersymmetry in traps
, 2007 We discuss the application of quantum-mechanical supersymmetry to particle traps. The supersymmetric-partner wave functions may be used to describe a valence fermion in a trap system with an isotropic harmonic-oscillator potential. Interactions with the core are incorporated analytically.

On ’t Hooft defects, monopole bubbling and supersymmetric quantum mechanics
Journal of High Energy Physics, 2018 We revisit the localization computation of the expectation values of ’t Hooft operators in N $$ \mathcal{N} $$ = 2* SU(N) theory on ℝ3 × S 1. We show that the part of the answer arising from “monopole bubbling” on ℝ3 can be understood as an equivariant ...

Supersymmetry in quantum mechanics: an extended view [PDF]
Journal of Physics A: Mathematical and General, 2004 The concept of supersymmetry in a quantum mechanical system is extended, permitting the recognition of many more supersymmetric systems, including very familiar ones such as the free particle. Its spectrum is shown to be supersymmetric, with space-time symmetries used for the explicit construction. No fermionic or Grassmann variables need to be invoked.
