We consider an infinite chain of coupled harmonic oscillators with a Langevin thermostat at the origin. In the high frequency limit, we establish the reflection-transmission coefficients for the wave energy for the scattering off the thermostat. To our surprise, even though the thermostat fluctuations are time-dependent, the scattering does not couple wave energy at various frequencies.

带有朗之万点温控器的谐波振荡器链的高频极限

我们考虑在原点具有朗之万恒温器的无限耦合谐振子链。在高频限制中,我们为恒温器散射的波能建立反射-透射系数。令我们惊讶的是,即使恒温器的波动与时间有关,散射也不会在各种频率下耦合波能。
