Magnetoresistance in chiral systems driven by inter-band spin-orbit coupling
Misa Nozaki, Takatoshi Fujita
Chiral-induced spin selectivity (CISS), in which electrons transmitted through nonmagnetic chiral materials exhibit strong spin-dependent transport, has attracted growing interest…
Connection between the GKSL master equation and the Landauer formula
Misa Nozaki, Takatoshi Fujita
We derive a current formula within the Gorini-Kossakowski-Sudarshan-Lindblad (GKSL) master equation formalism for a non-interacting system, and identify the conditions under which…
Roles of individual pigments in ultrafast excitation dynamics of light-harvesting phycobiliproteins revealed by recombinant techniques and two-dimensional electronic spectroscopy
Masaaki Tsubouchi, Takatoshi Fujita, Motoyasu Adachi +1
Phycobiliproteins serve as highly efficient light-harvesting antennae in cyanobacteria, yet the molecular factors governing their ultrafast energy relaxation and coherence dynamics…
Dependence of energy relaxation and vibrational coherence on the location of light-harvesting chromoproteins in photosynthetic antenna protein complexes

Towards Outperforming Classical Algorithms with Analog Quantum Simulators
Sarah Mostame, Joonsuk Huh, Christoph Kreisbeck +4
With quantum computers being out of reach for now, quantum simulators are the alternative devices for efficient and more exact simulation of problems that are challenging on conven…
Linear-algebraic bath transformation for simulating complex open quantum systems
Joonsuk Huh, Sarah Mostame, Takatoshi Fujita +2
In studying open quantum systems, the environment is often approximated as a collection of non-interacting harmonic oscillators, a configuration also known as the star-bath model.…
A stochastic reorganizational bath model for electronic energy transfer
Takatoshi Fujita, Joonsuk Huh, Alan Aspuru-Guzik
The fluctuations of optical gap induced by the environment play crucial roles in electronic energy transfer dynamics. One of the simplest approaches to incorporate such fluctuation…
