Quantum Mechanics Model on Kähler conifold

Stefano Bellucci, Armen Nersessian, Armen Yeranyan

We propose an exactly-solvable model of the quantum oscillator on the class of Kähler spaces (with conic singularities), connected with two-dimensional complex projective spaces. I…

Can string bits be supersymmetric?

Stefano Bellucci, Corneliu Sochichiu

We search for the possibility to have supersymmetric string bits at finite discretization . From a general setup we find that the string bits can be made supersymmetric modulo a…

Four-dimensional Hall mechanics as a particle on $\DC P^3$

Stefano Bellucci, Pierre-Yves Casteill, Armen Nersessian

In order to establish an explicit connection between four-dimensional Hall effect on and six-dimensional Hall effect on $\DC P^3$, we perform the Hamiltonian reduction of a p…

Many-Body Superconformal Systems from Hamiltonian Reductions

Stefano Bellucci, Anton Galajinsky, Sergey Krivonos

We propose a new reduction mechanism which allows one to construct n-particle (super)conformal theories with pairwise interaction starting from a composite system involving n(n-1)/…

Fermion Doubling and Berenstein--Maldacena--Nastase Correspondence

Stefano Bellucci, Corneliu Sochichiu

We show that the string bit model suffers from doubling in the fermionic sector. The doubling leads to strong violation of supersymmetry in the limit . Since there is a…

Constant magnetic field and 2d non-commutative inverted oscillator

Stefano Bellucci

We consider a two-dimensional non-commutative inverted oscillator in the presence of a constant magnetic field, coupled to the system in a ``symplectic'' and ``Poisson'' way. We sh…
