In this work, we solve the time-independent Schrödinger equation for a Landau system modulated by a non-Hermitian Hamiltonian. The system consists of a spinless particle in a uniform magnetic field submitted to action of a non-[Formula: see text] symmetric complex potential. Although the Hamiltonian is neither Hermitian nor [Formula: see text]-symmetric, we find that the Landau problem under study exhibits an entirely real energy spectrum.

Finite Extent

ABSTRACTA number of methods are formulated for solving the Schrödinger equation for systems of finite extent. The methods are developed in detail for the particular case of an electron moving in a Coulomb field (e.g. hydrogen-like atom), with a boundary consisting of a sphere of given radius. In the second part of the paper these results are transformed into those for an electron moving in a uniform magnetic field, the boundary of the system being cylindrical.

An electron moving on plane in a uniform magnetic field orthogonal to the plane is known as the Landau problem. Wigner functions for the Landau problem when the plane is noncommutative are found employing solutions of the Schrödinger equation as well as solving the ordinary ⋆-genvalue equation in terms of an effective Hamiltonian. Then, we let momenta and coordinates of the phase space be noncommutative and introduce a generalized ⋆-genvalue equation. We solve this equation to find the related Wigner functions and show that under an appropriate choice of noncommutativity relations they are independent of noncommutativity parameter.

The Ideal

The unified model of superconductivity has been discussed [1]. In the model the motion of phononic electron (PE) pairs is described by a non-linear schrödinger equation of PE pairs (SEPE). From SEPE the ideal conductivity in superconductors in external magnetic field has been derived. From wave property of motion of PE pairs, Josephson equations have been proven. From the formula of Tc, the relation of Tc to pressure p has been explained.

Approximate Description

The Schrödinger equation is considered for a simple model of a conduction electron in a uniform magnetic field. It is shown how this equation may be transformed into an approximate description of a different and simpler physical problem, from which the usual semiclassical results may be derived.
