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,…
Theoretical analysis of zirconium oxynitride/water interface using neural network potential
Akitaka Nakanishi, Shusuke Kasamatsu, Jun Haruyama +1
Zr oxides and oxynitrides are promising candidates to replace precious metal cathodes in polymer electrolyte fuel cells. Oxygen reduction reaction activity in this class of materia…
First-principles electronic structure investigation of HgBaCaCuO with the SCAN density functional
Alpin N. Tatan, Jun Haruyama, Osamu Sugino
We perform first-principles calculation to study the electronic structure of HgBaCaCuO copper oxides up to for the undoped parent compound $(…
Machine-Learning-Based Exchange-Correlation Functional with Physical Asymptotic Constraints
Ryo Nagai, Ryosuke Akashi, Osamu Sugino
Density functional theory is the standard theory for computing the electronic structure of materials, which is based on a functional that maps the electron density to the energy. H…
