Trace Formulas and Borg-type Theorems for Matrix-Valued Jacobi and Dirac Finite Difference Operators

open access: yes, 2005
Borg-type uniqueness theorems for matrix-valued Jacobi operators H and supersymmetric Dirac difference operators D are proved. More precisely, assuming reflectionless matrix coefficients A,B in the self-adjoint Jacobi operator H=AS++A-S-+B (with S± the ...

Approximation of eigenvalues of some unbounded self-adjoint discrete Jacobi matrices by eigenvalues of finite submatrices [PDF]

open access: yesOpuscula Mathematica, 2007
We investigate the problem of approximation of eigenvalues of some self-adjoint operator in the Hilbert space \(l^2(\mathbb{N})\) by eigenvalues of suitably chosen principal finite submatrices of an infinite Jacobi matrix that defines the operator ...

Predicting dynamics from flows of the eigenstate thermalization hypothesis

open access: yesPhysical Review Research
Analytical treatments of far-from-equilibrium quantum dynamics are few, even in well-thermalizing systems. The celebrated eigenstate thermalization hypothesis (ETH) provides a post hoc ansatz for the matrix elements of observables in the eigenbasis of a ...

Issues of linearization of a twoaphase boost dcadc converter applied in the power supply systems operating on renewable energy sources

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2017
Renewable energy resources, for example, photovoltaic elements and wind turbines draw the increasing attention due to energy shortage and depletion of energy sources. Such energy sources usually give low voltage output.
