“…Quantum wave functions correlated with classical periodic orbits have been verified to play an important role in explaining the quantum phenomena such as shell effects in nuclei and metallic clusters [22,23], conductance fluctuations in mesoscopic quantum transports [24,25], and oscillations in photodetachment cross sections [26,27]. On the other hand, thanks to Hamilton's ingenious optico-mechanical theory [28][29][30], modern laser resonators have been widely exploited to analogously explore the formation of quantum coherent waves in the mesoscopic regime [31][32][33][34][35][36][37][38][39][40]. As shown in Fig.…”
