Matrices with integer eigenvalues for all permutations of coefficients (thanks to Pythagoras!)
Michael J. W. Hall
It is shown that Pythagorean triples can be used to generate matrices that have integer eigenvalues for all permutations of their coefficients, via simple formulas. For example, ea…

Eternal non-Markovianity is generic for the spin-boson model
Li Li, Michael J. W. Hall
The spin-boson model describes a qubit coupled to a bosonic bath in thermal equilibrium, and is applicable to a wide range of physical contexts. We show that two weak conditions fo…

Exact Non-Markovian master equation for the Spin-Boson and Jaynes-Cummings models
L. Ferialdi
We provide the exact non-Markovian master equation for a two-level system interacting with a thermal bosonic bath, and we write the solution of such a master equation in terms of t…
