Three dimensional N=4 supersymmetric mechanics with Wu-Yang monopole
Stefano Bellucci, Sergey Krivonos, Anton Sutulin
We propose Lagrangian and Hamiltonian formulations of a N=4 supersymmetric three-dimensional isospin-carrying particle moving in the non-Abelian field of a Wu-Yang monopole and in…
State-space Correlations and Stabilities
Stefano Bellucci, Bhupendra Nath Tiwari
The state-space pair correlation functions and notion of stability of extremal and non-extremal black holes in string theory and M-theory are considered from the viewpoints of ther…
An Exact Fluctuating 1/2-BPS Configuration
Stefano Bellucci, Bhupendra Nath Tiwari
This work explores the role of thermodynamic fluctuations in the two parameter giant and superstar configurations characterized by an ensemble of arbitrary liquid droplets or irreg…
Fermionic Casimir effect for parallel plates in the presence of compact dimensions with applications to nanotubes
S. Bellucci, A. A. Saharian
We evaluate the Casimir energy and force for a massive fermionic field in the geometry of two parallel plates on background of Minkowski spacetime with an arbitrary number of toroi…
Potentials in N=4 superconformal mechanics
Stefano Bellucci, Sergey Krivonos
Proceeding from nonlinear realizations of (super)conformal symmetries, we explicitly demonstrate that adding the harmonic oscillator potential to the action of conformal mechanics…
SAM Lectures on Extremal Black Holes in d=4 Extended Supergravity
S. Bellucci, S. Ferrara, M. Gunaydin +1
We report on recent results in the study of extremal black hole attractors in N=2, d=4 ungauged Maxwell-Einstein supergravities. For homogeneous symmetric scalar manifolds, the thr…
Second Hopf map and Yang-Coulomb system on 5d (pseudo)sphere
Stefano Bellucci, Francesco Toppan, Vahagn Yeghikyan
Using the second Hopf map, we perform the reduction of the eight-dimensional (pseudo)spherical (Higgs)oscillator to a five-dimensional system interacting with a Yang monopole. Then…
Fermionic Casimir densities in toroidally compactified spacetimes with applications to nanotubes
S. Bellucci, A. A. Saharian
Fermionic condensate and the vacuum expectation values of the energy-momentum tensor are investigated for a massive spinor fields in higher-dimensional spacetimes with an arbitrary…
