Quantum backflow is an interference effect in which a matter-wave packet comprised of only
plane waves with non-negative momenta exhibits negative probability flux. Here we show …

Exact solution of the Schrödinger equation is given for a particle inside a hard sphere whose
wall is moving with a constant velocity. Numerical computations are presented for both …

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 …

Weak values, obtained from weak measurements, attempt to describe the properties of a
quantum system as it evolves from an initial to a final state, without practically altering this …

Solutions to the Schrödinger equation are examined for a particle inside a cylindrical trap of
a circular time-dependent cross-section. Analytical expressions for energy and momentum …

The process of diffraction in time of a standing matter wave is studied. This case occurs
generally when a quantum particle is confined in a trap or infinite potential well. First of all …

Diffraction in time and early-arrival phenomena will be studied in the context of dissipative
systems. This theoretical consideration is done by using the linear scaled wave equation …

پدیده‌های پراش در زمان و زود-ورود در مورد سیستم‌های اتلافی مطالعه خواهند شد. این بررسیِ نظری با
استفاده از معادلۀ موج مقیاس شدۀ خطی که در چارچوب نظریۀ کلدیرولا-کانای برای گذار پیوستۀ …‎

• An interesting feature of the solutions for cut-off initial waves, occurring both in the free
case and in the presence of a potential interaction is that, if initially there is a zero probability …

In this study, the scattering of matter waves that accompany to the quantum particles by an
absorbing half-plane is examined. A quantum shutter, which is opened at an initial time, is …
