A pseudo-unitary ensemble of random matrices, PT-symmetry and the Riemann Hypothesis
Zafar Ahmed, Sudhir R. Jain
An ensemble of 2 x 2 pseudo-Hermitian random matrices is constructed that possesses real eigenvalues with level-spacing distribution exactly as for the Gaussian Unitary Ensemble fo…
A note on Coulomb scattering amplitude
Zafar Ahmed
The summation of the partial wave series for Coulomb scattering amplitude, is avoided because the series is oscillatorily and divergent. Instead, is obtained by s…
A practice problem for Schr{ö}dinger transmission
Zafar Ahmed
We present the case of quantal transmission through a smooth, single-piece exponential potential, , in contrast to the piece-wise continuous potentials, as a ped…
Some Aspects of Scattering in (Non) Commutative Gauge Theories
Zafar Ahmed, Tapobrata Sarkar
We study almost-forward scattering in the context of usual and non-commutative QED. We study the semi-classical behaviour of particles undergoing this scattering process in the two…
Brownian motion model of random matrices revisited
Sudhir R. Jain, Zafar Ahmed
We present a modified Brownian motion model for random matrices where the eigenvalues (or levels) of a random matrix evolve in "time" in such a way that they never cross each other…
