A Unified Description of Electron-Phonon Coupling and Ion Migration in Metal Halide Perovskites
Bo Cai, Yan Yang, Yoshiki Sugai +11
The remarkable optoelectronic properties of metal halide perovskites are closely linked to their unusually soft and polar chemical bonds that enable both strong electron-phonon int…
Optimal Harvesting of a Stochastic Logistic Model Driven by One-Sided Tempered Stable Process
Wenmin Deng, Fu Zhang
This paper investigates a class of stochastic Logistic harvesting models driven by tempered stable processes, with a one-sided power-law Lévy measure. We establish threshold condi…
Collective quantum tunneling with time-dependent generator coordinate method
Wenmin Deng, Guangping Chen, Ganlong Ding +3
Inspired by the work of McGlynn and Simenel [Phys. Rev. C {\bf 102}, 064614 (2020)], this study investigates the quantum tunneling of two interacting distinguishable particles in t…
Optimal Harvesting of a Stochastic Lotka-Volterra Competition Model with Periodic Coefficients
Wenmin Deng, Fu Zhang
This paper systematically investigates the optimal harvesting of a stochastic Lotka-Volterra competition model with periodic coefficients. Sufficient conditions for the extinction…
