Resonances in a Dirichlet quantum waveguide coupled to a cavity
Sylwia Kondej, Nikoloz Kurtskhalia
We consider a Dirichlet waveguide in () with an attached cavity. We show that if the cavity admits a small gap, then the original embedded eigenvalues turn…

Modified light-cylinder and centrifugal acceleration in Schwarzschild geometry
Nikoloz Kurtskhalia, Nikolai Maltsev, Zaza N. Osmanov
We examine the motion of an electron constrained to follow a magnetic field line near a primordial sub-stellar mass black hole. Earlier studies treated the problem in flat (Minkows…
