Description

The eigenmode for a resonator containing a two-dimensional electron system (2DES), formed on the surface of liquid helium is investigated. It is shown that anti-crossing phenomena occur near the crossing point ω0 ωc, where ω0 is the eigenmode of the resonator and ωc is the cyclotron frequency. The coupling constant is a flexible parameter, i. e., sensitive to magnetic field and electron density. A finite coupling leas to a perturbation of the eigenmode of the resonator in presence of the 2DES. The theory fits the experimental data

Abstract (Russian)

Изучается собственная мода (СМ) резонатора, содержащего двухмерную электронную систему (2МЭС), образованную на поверхности жидкого гелия. Показано, что явления антипересечения вблизи точки ω0 = ωc (ω0 - СМ резонатора, ωc - циклотронная частота). Постоянная связи - это параметр, зависящий от магнитного поля и концентрации электронов. Конечная связь приводит к возмущению СМ в присутствии 2МЭС. Теория согласуется с экспериментом
