Isospectrality of conventional and new extended potentials, second-order supersymmetry and role of PT symmetry
B. Bagchi, C. Quesne, R. Roychoudhury
We develop a systematic approach to construct novel completely solvable rational potentials. Second-order supersymmetric quantum mechanics dictates the latter to be isospectral to…
Ferrers Dimension and Boxicity
Soumyottam Chatterjee, Shamik Ghosh
This note explores the relation between the boxicity of undirected graphs and the Ferrers dimension of digraphs.
Quantum Isometry Group for Spectral Triples with Real Structure
Debashish Goswami
Given a spectral triple of compact type with a real structure in the sense of [Dabrowski L., J. Geom. Phys. 56 (2006), 86-107] (which is a modification of Connes' original definiti…
Spin-Orbit gauge and quantum spin Hall effect
B. Basu, P. Bandyopadhyay
We have shown that the non-Abelian spin-orbit gauge field strength of the Rashba and Dresselhaus interactions, when split into two Abelian field strengths, the Hamiltonian of the s…
Linear Relations Among Poincare Series via Harmonic Weak Maass Forms
Robert C. Rhoades
We discuss the problem of the vanishing of Poincaré series. This problem is known to be related to the existence of weakly holomorphic forms with prescribed principal part. The obs…
Incompressibility and normal minimal surfaces
Tejas Kalelkar
In this paper we describe a procedure for refining the given triangulation of a 3-manifold that scales the PL-metric according to a given weight function while creating no new norm…
