Non-catastrophic resonant states in one dimensional scattering from a rising exponential potential
Zafar Ahmed, Lakshmi Prakash, Shashin Pavaskar
Investigation of scattering from rising potentials has just begun, these unorthodox potentials have earlier gone unexplored. Here, we obtain reflection amplitude () for scatt…
One dimensional scattering from two-piece rising potentials: a new avenue of resonances
Zafar Ahmed, Shashin Pavaskar, Lakshmi Prakash
We study scattering from potentials that rise monotonically on one side; this is generally avoided. We report that resonant states are absent in such potentials when they are smoot…
Anti-symmetric square well and barrier potential between two rigid walls
Zafar Ahmed, Shashin Pavaskar, Indresh Yadav +1
We study an anti-symmetric (square) well and barrier potential of depth/height placed between two rigid walls. Unlike the usual double-well, here the closely lying sub-barr…
Special rectangular (double-well and hole) potentials
Zafar Ahmed, Tanayveer Bhatia, Shashin Pavaskar +1
We revisit a rectangular barrier as well as a rectangular well (pit) between two rigid walls. The former is the well known double-well potential and the latter is a hole potential.…
