Coherent scattering from semi-infinite non-Hermitian potentials

Zafar Ahmed, Dona Ghosh, Sachin Kumar

When two identical (coherent) beams are injected at a semi-infinite non-Hermitian medium from left and right, we show that both reflection $(r_{L}, r_{R})$ and transmission $(t_{L}, t_{R})$ …

Solvable models of an open well and a bottomless barrier in 1-D

Zafar Ahmed, Dona Ghosh, Sachin Kumar +1

We present one dimensional potentials $V (x) = V_{0} [e^{2∣ x ∣/ a} - 1]$ as solvable models of a well $(V_{0} > 0)$ and a barrier ( $V_{0} < 0$ ). Apart from being new addition to solvable models, th…
