Planar waveguide with "twisted" boundary conditions: discrete spectrum
Denis Borisov, Giuseppe Cardone
We consider a planar waveguide with combined Dirichlet and Neumann conditions imposed in a "twisted" way. We study the discrete spectrum and describe it dependence on the configura…
A Nonsingular Brans Wormhole: An Analogue to Naked Black Holes
Amrita Bhattacharya, Ramil Izmailov, Ettore Laserra +1
In a recent paper, we showed the Jordan frame vacuum Brans Class I solution provided a wormhole analogue to Horowitz-Ross naked black hole in the wormhole range -3/2<ω<-4/3. Therea…
The general form-invariance principle
Vitaliy Voytik
We postulate the applicability of the general form-invariance principle in special relativity. It is shown that this principle holds in classical mechanics. Some examples of transf…
The effective Hamiltonian for thin layers with non-Hermitian Robin-type boundary conditions
Denis Borisov, David Krejcirik
The Laplacian in an unbounded tubular neighbourhood of a hyperplane with non-Hermitian complex-symmetric Robin-type boundary conditions is investigated in the limit when the width…
