Exact propagating Dirac wave packets in an attractive Coulomb-like potential
Siddhant Das
We construct exact, positive-energy, normalizable wave-packet solutions of the Dirac equation in the axisymmetric potential -- to our knowledge, the first such soluti…

Double-slit experiment revisited
Siddhant Das, Dirk-André Deckert, Leopold Kellers +2
The double-slit experiment is one of the quintessential quantum experiments. However, it tends to be overlooked that a theoretical account of this experiment requires the specifica…

Spin-aware movement of electrons and time-of-flight momentum spectroscopy
Siddhant Das
In the framework of the de Broglie-Bohm pilot-wave theory, or Bohmian mechanics, we examine two pedagogical problems that illustrate the bound and unbound motion of spin-1/2 partic…
