Extended supersymmetries and the Dirac operator [PDF]

open access: greenAnnals of Physics, 2004
We consider supersymmetric quantum mechanical systems in arbitrary dimensions on curved spaces with nontrivial gauge fields. The square of the Dirac operator serves as Hamiltonian. We derive a relation between the number of supercharges that exist and restrictions on the geometry of the underlying spaces as well as the admissible gauge field ...

Extended Supersymmetry and Superfields

open access: green, 2010
This thesis concerns the reconstruction of N=1 supersymmetry, starting with the Standard Model. Next, we partially construct an N=2 superfield theory. The differential representation of the N=2 supercharges is found. Issues regarding the necessity of mixing left and right chirality in extended supersymmetry is discussed, and possible ways to circumvent

Worldsheet (anti)instanton bound states in type II on T 2

open access: yesJournal of High Energy Physics, 2020
The 1/8 BPS D 6ℛ4 coupling in type II string theory compactified on T 2 receives contributions from worldsheet instantons and anti-instantons wrapping the T 2, up to genus three in string perturbation theory.

Triplet-Singlet Emission of d-Block Metal Complexes Characterized by Spin-Orbit Natural Transition Orbitals. [PDF]

open access: yesChemistryOpen
In the present study, the SO‐ NTO technique was applied to analyze triplet‐to‐singlet emission in a set of transition metal complexes with Mo, W, Re, and Ir. The source of intensity in the spin‐orbit forbidden transitions has been demonstrated and discussed.

Quantum extended supersymmetries

open access: yesAnnalen der Physik, 2004
AbstractWe analyse some quantum multiplets associated with extended supersymmetries. We study in detail the general form of the causal (anti)commutation relations. The condition of positivity of the scalar product imposes severe restrictions on the (quantum) model.

Nonlinear N = 2 $$ \mathcal{N}=2 $$ global supersymmetry

open access: yesJournal of High Energy Physics, 2017
We study the partial breaking of N = 2 $$ \mathcal{N}=2 $$ global supersymmetry, using a novel formalism that allows for the off-shell nonlinear realization of the broken supersymmetry, extending previous results scattered in the literature.

Superconformal duality-invariant models and N $$ \mathcal{N} $$ = 4 SYM effective action

open access: yesJournal of High Energy Physics, 2021
We present N $$ \mathcal{N} $$ = 2 superconformal U(1) duality-invariant models for an Abelian vector multiplet coupled to conformal supergravity. In a Minkowski background, such a nonlinear theory is expected to describe (the planar part of) the low ...

Vacua of ω-deformed SO(8) supergravity

open access: yesJournal of High Energy Physics, 2022
We perform a detailed analysis of the vacua of ω-deformed SO(8) supergravity in four dimensions. In particular, using Tensorflow-based numerical methods, we track how the equilibria of the theory change when varying the electric-magnetic deformation ...
