In this paper we illustrate the dynamics of a solid-state spin system in two regimes: in the short-time, few-spin limit when evolving under a non-secular Hamiltonian, and in the the long-time, many-spin limit when evolving under the secular dipolar Hamiltonian of the spin system. In the...

There are several experimental indications of spin-triplet Cooper pairing in UTe2, including a negligible (small) decrease in the temperature dependence of the local spin susceptibility in the superconducting state, as inferred from 125Te-nuclear magnetic resonance (NMR) Knight shift measurements for ...

Spin relaxation in a strong-coupling regime (with respect to the spin system) is investigated in detail based on the spin-boson model in a stochastic limit. We find a bifurcation phenomenon in temperature dependence of relaxation constants, which is never observed in the weak-coupling regime. We...
