Note on Angular Momentum of Phonons in Chiral Crystals
Akihito Kato, Jun-ichiro Kishine
Phonon angular momentum in chiral materials has been widely studied in spintronics and condensed matter physics. In chiral crystals, this is not the conserved quantity in contrast…
Chirality-Induced Spin Filtering in Pseudo Jahn-Teller Molecules
Akihito Kato, Hiroshi M. Yamamoto, Jun-ichiro Kishine
Chirality-induced spin selectivity (CISS) refers to an ability to induce a spin polarization of an electron transmitted through chiral materials. An important experimental observat…
Hierarchical Equations of Motion Approach to Quantum Thermodynamics
Akihito Kato, Yoshitaka Tanimura
We present a theoretical framework to investigate quantum thermodynamic processes under non-Markovian system-bath interactions on the basis of the hierarchical equations of motion…
Non-Markovian quantum-classical ratchet for ultrafast long-range electron-hole separation in condensed phases
Akihito Kato, Akihito Ishizaki
In organic photovoltaic systems, a photogenerated molecular exciton in the donor domain dissociates into a hole and an electron at the donor/acceptor heterojunction, and subsequent…
Quantum Heat Current under Non-perturbative and Non-Markovian Conditions: Applications to Heat Machines
Akihito Kato, Yoshitaka Tanimura
We consider a quantum system strongly coupled to multiple heat baths at different temperatures. Quantum heat transport phenomena in this system are investigated using two definitio…
Quantum Suppression of Ratchet Rectification in a Brownian System Driven by a Biharmonic Force
Akihito Kato, Yoshitaka Tanimura
We rigorously investigate the quantum dissipative dynamics of a ratchet system described by a periodic potential model based on the Caldeira-Leggett Hamiltonian with a biharmonic f…
