Open Quantum System Theory of Muon Spin Relaxation in Materials
Elvis F. Arguelles, Osamu Sugino
We present a non-Markovian theory of muon spin relaxation that treats the implanted muon as an open quantum spin coupled to a temporally correlated local magnetic environment. Usin…

Dynamics with Simultaneous Dissipations to Fermionic and Bosonic Reservoirs
Elvis F. Arguelles, Osamu Sugino
We introduce a non-phenomenological framework based on the influence functional method to incorporate simultaneous interactions of particles with fermionic and bosonic thermal rese…

Magnetic phases of electron-doped infinite-layer SrLaCuO from first-principles density functional calculations
Alpin N. Tatan, Jun Haruyama, Osamu Sugino
The magnetic phases of electron-doped infinite-layer SrLaCuO are elucidated by first-principles density functional calculations. The antiferromagnetic parent state,…
