Even order periodic operators on the real line

Andrey Badanin, Evgeny Korotyaev

We consider $2 p \geq 4$ order differential operator on the real line with a periodic coefficients. The spectrum of this operator is absolutely continuous and is a union of spectral b…

Periodic Jacobi operator with finitely supported perturbations

Alexei Iantchenko, Evgeny Korotyaev

We describe the spectral properties of the Jacobi operator $(H y)_{n} = a_{n - 1} y_{n - 1} + a_{n} y_{n + 1} + b_{n} y_{n},$ $n \in Z,$ with $a_{n} = a_{n}^{0} + u_{n},$ $b_{n} = b_{n}^{0} + v_{n},$ where sequences $a_n^0…

Periodic Jacobi operator with finitely supported perturbation on the half-lattice

Alexei Iantchenko, Evgeny Korotyaev

We consider the periodic Jacobi operator $J$ with finitely supported perturbations on the half-lattice. We describe all eigenvalues and resonances of $J$ and give their properties.…

Zigzag nanoribbons in external electric and magnetic fields

Evgeny L. Korotyaev, Anton A. Kutsenko

We consider the Schrödinger operators on zigzag nanoribbons (quasi-1D tight-binding models) in external magnetic fields and an electric potential $V$ . The magnetic field is perpend…
