The role of anharmonicity in single-molecule spin-crossover

Chuan Guan, Yun-An Yan

We exploit the system-bath paradigm to investigate anharmonicity effects of vibrations on spin-crossover (SCO) in a single molecule. Focusing on weak coupling, we use the linear re…

Accessing the bath information in open quantum systems with the stochastic c-number Langevin equation method

Zheng-Yang Zhou, Yun-An Yan, Stephen Hughes +2

In traditional open quantum systems, the baths are usually traced out so that only the system information is left in the equations of motion. However, recent studies reveal that us…
