Coalescing versus merging of energy levels in one-dimensional potentials
Zafar Ahmed, Sachin Kumar, Achint Kumar +1
The sub-barrier pairs of energy levels of a Hermitian one-dimensional symmetric double well potential are known to merge into one, if the inter-well distance () is increased slo…

Hermitian Hamiltonians: Matrix versus Schrdinger's
Zafar Ahmed, Mohammad Irfan, Achint Kumar +1
We draw attention to the fact that a Hermitian matrix is always diagonalizable and has real discrete spectrum whereas the Hermitian Schr{ö}dinger Hamiltonian: , may…

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.…
