Phase Transitions in Layered Film Systems,We consider the interaction of rotons with quantized vortex lines in the theory of mutual friction. A good account is given of mutual friction at low temperatures and under pressure. We also consider collisions of rotons with rotons in the context of a recent experiment by Forbes and Wyatt.作者: 令人心醉 時(shí)間: 2025-3-26 03:16 作者: 卷發(fā) 時(shí)間: 2025-3-26 05:04 作者: DENT 時(shí)間: 2025-3-26 09:38
