A remark on Chebyshev rational functions, multipoint Padé approximants and Noise
Maxim Derevyagin, Max Meynig
The paper studies Chebyshev rational functions and shows how they generate multipoint Padé approximants, providing recurrence relations and a Thiele-type continued fraction, and ex…

Jacobi matrices that realize perfect quantum state transfer and early state exclusion
Rachel Bailey, Sara Costa, Maxim Derevyagin +2
In this paper we show how to construct 1D Hamiltonians, that is, Jacobi matrices, that realize perfect quantum state transfer and also have the property that the overlap of the tim…
