Topics in Supersymmetry Breaking and Gauge/Gravity Dualities [PDF]
, 2010 The thesis covers two topics in string theory and quantum field theory. First, we realize metastable vacua in various supersymmetric gauge theories. Specifically, we consider the Coulomb branch of any N = 2 supersymmetric gauge theory, and perturb it by ...

The superfield quantisation of a superparticle action with an extended line element [PDF]
, 2005 A massive superparticle action based on the generalised line element in N = 1 global superspace is quantised canonically. A previous method of quantising this action, based on a Fock space analysis, showed that states existed in three supersymmetric ...

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.

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 $S^1$.

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 $

Decoherence and Ontology, or: How I Learned To Stop Worrying And Love FAPP [PDF]
, 2010 I make the case that the Universe according to unitary (no-collapse) quantum theory has a branching structure, and so can literally be regarded as a "many-worlds" theory.

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
