The role of power law nonlinearity in the discrete nonlinear Schrödinger equation on the formation of stationary localized states in the Cayley tree

K. Kundu, B. C. Gupta

We study the formation of stationary localized states using the discrete nonlinear Schrödinger equation in a Cayley tree with connectivity $K$ . Two cases, namely, a dimeric power l…

Specific heat of high temperature superconductors: Role of $∣ ψ ∣^{4}$ term in Ginzburg--Landau free energy

Bikash. Ch. Gupta, K. K. Nanda

We have derived the expression for the specific heat by using Ginzburg-Landau (GL) theory by taking $∣ ψ ∣^{4}$ into account in the Hartree approximation. Without this term, t…
