Spectral gap of random hyperbolic graphs and related parameters
(Inst. Mathematical Statistics, 2018-04)
Random hyperbolic graphs have been suggested as a promising model of social networks. A few of their fundamental parameters have been studied. However, none of them concerns their spectra. We consider the random hyperbolic ...
Discrete spectrum of quantum Hall effect Hamiltonians I. Monotone edge potentials
(EUROPEAN MATHEMATICAL SOC, 2011)
We consider the unperturbed operator H-0 = (-i del - A)(2) + W, self-adjoint in L-2(R-2). Here A is a magnetic potential which generates a constant magnetic field b > 0, and the edge potential W is a non-decreasing ...
Low Energy Asymptotics of the Spectral Shift Function for Pauli Operators with Nonconstant Magnetic Fields
(KYOTO UNIV, 2010)
We consider the 3D Pauli operator with nonconstant magnetic field B of constant direction, perturbed by a symmetric matrix-valued electric potential V whose coefficients decay fast enough at infinity We investigate the ...
Discrete spectrum of quantum Hall effect Hamiltonians II: Periodic edge potentials
(IOS PRESS, 2012)
We consider the unperturbed operator H-0 := (-i del-A)(2) + W, self-adjoint in L-2(R-2). Here A is a magnetic potential which generates a constant magnetic field b > 0, and the edge potential W = (W) over bar is a T-periodic ...
