Improving the Cauchy-Schwarz inequality
Kamal Bhattacharyya
We highlight overlap as one of the simplest inequalities in linear space that yields a number of useful results. One obtains the Cauchy-Schwarz inequality as a special case. More i…
Uncertainty relations for incompatible observables: Newer results versus modified strategies
Kamal Bhattacharyya
Two special situations where the standard uncertainty product inequality appears to be useless are modified. One such case is noted to also trivialize the recently-introduced alter…
On two classes of perturbations: Role of signs of second-order Rayleigh-Schrödinger energy corrections
Kamal Bhattacharyya
We distinguish two extreme classes of perturbation problems depending on the signs of second-order energy corrections and argue why it is generally much more probable to obtain a n…
Perturbative and non-perturbative studies with the delta function potential
Nabakumar Bera, Kamal Bhattacharyya, Jayanta K. Bhattacharjee
We show that the delta function potential can be exploited along with perturbation theory to yield the result of certain infinite series. The idea is that any exactly soluble poten…
