Bohr Sommerfeld quantisation and molecular potentials
Shayak Bhattacharjee, D. S. Ray, J. K. Bhattacharjee
We use the Bohr Sommerfeld quantization rule along with a perturbative evaluation of the action intergral to find exact energy levels for the Pöschl-Teller potential (both hyperbol…
Renormalization group and isochronous oscillations
Amartya Sarkar, J. K. Bhattacharjee
We show how the condition of isochronicity can be studied for two dimensional systems in the renormalization group (RG) context. We find a necessary condition for the isochronicity…
Distribution Function of the End-to-End Distance of Semiflexible Polymers
J. K. Bhattacharjee, D. Thirumalai, J. D. Bryngelson
The distribution function of the end-to-end distance of a semiflexible polymer, G(R;L) (where R denotes the end-to-end distance and L the contour length), is calculated using a mea…
Thermodynamic stability of folded proteins against mutations
H. J. Bussemaker, D. Thirumalai, J. K. Bhattacharjee
By balancing the average energy gap with its typical change due to mutations for protein-like heteropolymers with M residues, we show that native states are unstable to mutations o…
