analyze the coupling... | 2209.07391v1 |
2022-09-21 | Two-Nanorod PT Structure with Large Spontaneous Enhancement | Two-mode coupling is very common and basic in optics. Recently, a lot more
works are focusing on the optical mode coupling with gain and loss due to its

protocol that ca... | 2210.04751v2 |
2022-10-10 | Understanding the Energy Gap Law under Vibrational Strong Coupling | The rate of non-radiative decay between two molecular electronic states is
