Comment on 'Anyon in External Elecromagnetic Field: Hamiltonian and Lagrangian Formulation'
Abbas Ali, Avinash Khare
We point out that in a recent paper by Chaichian et al. (Phys. Rev.Lett71(1993)3405) Dirac quantization procedure is not properly followed as a result of which the resulting quantu…
Is the Lowest Order Supersymmetric WKB Approximation Exact for All Shape Invariant Potentials ?
D. T. Barclay, Avinash Khare, U. Sukhatme
It has previously been proved that the lowest order supersymmetric WKB approximation reproduces the exact bound state spectrum of shape invariant potentials. We show that this is n…
Supersymmetry,Shape Invariance and Exactly Solvable Noncentral Potentials
Avinash Khare, Rajat K. Bhaduri
Using the ideas of supersymmetry and shape invariance we show that the eigenvalues and eigenfunctions of a wide class of noncentral potentials can be obtained in a closed form by t…
Some Exactly Solvable Three-Body Problems in One dimension
Avinash Khare, Rajat K. Bhaduri
The three-body problem in one-dimension with a repulsive inverse square potential between every pair was solved by Calogero. Here, the known results of supersymmetric quantum mecha…
Spontaneous Symmetry Breaking and the Renormalization of the Chern-Simons Term
Avinash Khare, R. B. MacKenzie, P. K. Panigrahi +1
We calculate the one-loop perturbative correction to the coefficient of the \cs term in non-abelian gauge theory in the presence of Higgs fields, with a variety of symmetry-breakin…
