Obtaining eigenvalues and solutions for a class of differential equations using Casimir operator
Karmadeva Maharana
Using the group theoretic method of spectrum generating algebras a class of differential equations is obtained whose eigenvalues are calculated without explicitly solving the equat…
Group analysis of Schroedinger equation with generalised Kratzer type potential
Karmadeva Maharana
Using the method of spectrum generating algebra, we analyze one dimensional Schroedinger equation with potential in the form ${C\over{x^2} + {D\over{x}}$ to obtain a clas…
Symmetry analysis for a charged particle in a certain varying magnetic field
Karmadeva Maharana
We analyze the classical equations of motion for a particle moving in the presence of a static magnetic field applied in the direction, which varies as . We…
Nonlinear Dirac and diffusion equations in 1 + 1 dimensions from stochastic considerations
Karmadeva Maharana
We generalize the method of obtaining the fundamental linear partial differential equations such as the diffusion and Schrodinger equation, Dirac and telegrapher's equation from a…
A tachyonic extension of the stringy no-go theorem
Swapna Mahapatra, Karmadeva Maharana, Lambodar P. Singh
We investigate the tachyon-dilaton-metric system to study the "graceful exit" problem in string theoretic inflation, where tachyon plays the role of the scalar field. From the phas…
