Ripplonic Lamb shift for electrons on liquid helium
D. Konstantinov, K. Kono, M. J. Lea +1
We study the shift of the energy levels of electrons on helium surface due to the coupling to the quantum field of surface vibrations. As in quantum electrodynamics, the coupling i…
Temperature Dependent Energy Levels of Electrons on Liquid Helium
E. Collin, W. Bailey, P. Fozooni +4
We present measurements of the resonant microwave absorption by the Rydberg energy levels of surface state electrons on the surface of superfluid liquid helium, in the frequency ra…
Bistability and Hysteresis of Intersubband Absorption in Strongly Interacting Electrons on Liquid Helium
Denis Konstantinov, M. I. Dykman, M. J. Lea +2
We study nonlinear inter-subband microwave absorption of electrons bound to the liquid helium surface. Already for a comparatively low radiation intensity, resonant absorption due…
Resonant Correlation-Induced Optical Bistability in an Electron System on Liquid Helium
Denis Konstantinov, M. I. Dykman, M. J. Lea +2
We show that electrons on liquid helium display intrinsic bistability of resonant inter-subband absorption. The bistability occurs for comparatively weak microwave power. The under…
Microwave saturation of the Rydberg states of electrons on helium
E. Collin, W. Bailey, P. Fozooni +5
We present measurements of the resonant microwave excitation of the Rydberg energy levels of surface state electrons on superfluid helium. The temperature dependent linewidth agree…
Hall magnetocapacitance in two-dimensional electron systems
A. M. C. Valkering, P. K. H. Sommerfeld, R. A. M. van de Ven +4
The magnetocapacitance of a two-dimensional electron system (2DES) is investigated experimentally, both under and away from Quantum Hall (QH) conditions, at frequencies between 1 k…
Magneto-shear modes and a.c. dissipation in a two-dimensional Wigner crystal
Yuri G. Rubo, M. J. Lea
The a.c. response of an unpinned and finite 2D Wigner crystal to electric fields at an angular frequency has been calculated in the dissipative limit, , where …
Internal Forces and the Magnetoconductivity of a Nondegenerate 2D Electron Fluid
P. Fozooni, P. J. Richardson, M. J. Lea +3
The forces on individual electrons in an unscreened nondegenerate electron fluid, due to electron density fluctuations, have been calculated using Monte Carlo simulations and deter…
