Relativistic electron wave packets featuring persistent quantum backflow
Siddhant Das
Closed-form, normalizable solutions of Dirac's equation propagating within a semi-infinite cylindrical waveguide are obtained in terms of ordinary and modified Bessel functions. Th…

Questioning the adequacy of certain quantum arrival-time distributions
Siddhant Das, Ward Struyve
It is shown that a class of exponentially decaying time-of-arrival probability distributions suggested by Włodarz, Marchewka and Schuss, and Jurman and Nikolić, as well as a semicl…

Times of Arrival and Gauge Invariance
Siddhant Das, Markus Nöth
We revisit the arguments underlying two well-known arrival-time distributions in quantum mechanics, viz., the Aharonov-Bohm and Kijowski (ABK) distribution, applicable for freely m…
