Spectroscopic Evidence of the Aharonov-Casher effect in a Cooper Pair Box
M. T. Bell, W. Zhang, L. B. Ioffe +1
We have observed the effect of the Aharonov-Casher (AC) interference on the spectrum of a superconducting system containing a symmetric Cooper pair box (CPB) and a large inductance…
Probing Electron Interactions in a Two-Dimensional System by Quantum Magneto-Oscillations
V. M. Pudalov, M. E. Gershenson, H. Kojima
We have experimentally studied the renormalized effective mass m* and Dingle temperature T_D in two spin subbands with essentially different electron populations. Firstly, we found…
Magnetic Field Driven Quantum Phase Transitions in Josephson Arrays
J. Paramanandam, M. T. Bell, L. B. Ioffe +1
We have studied the magnetic-field-driven quantum phase transitions in Josephson junction arrays with a large coordination number. The characteristic energies were extracted in bot…
Interaction Effects in Conductivity of a Two-Valley Electron System in High-Mobility Si Inversion Layers
N. N. Klimov, D. A. Knyazev, O. E. Omel'yanovskii +3
We have measured the conductivity of high-mobility (001) Si metal-oxide-semiconductor field effect transistors (MOSFETs) over wide ranges of electron densities n=(1.8-15)x10^11cm^2…
On the Electron-Electron Interactions in Two Dimensions
V. M. Pudalov, M. E. Gershenson, H. Kojima
In this paper, we analyze several experiments that address the effects of electron-electron interactions in 2D electron (hole) systems in the regime of low carrier density. The int…
Millisecond Electron-Phonon Relaxation in Ultrathin Disordered Metal Films at Millikelvin Temperatures
M. E. Gershenson, D. Gong, T. Sato +2
We have measured directly the thermal conductance between electrons and phonons in ultra-thin Hf and Ti films at millikelvin temperatures. The experimental data indicate that elect…
Low-temperature dephasing in disordered conductors: experimental aspects
Michael Gershenson
What is the lowest temperature to which one can trace the growth of the dephasing time in low-dimensional conductors? I consider the fundamental limitation, the crossover from weak…
Comment on "Quantum Decoherence in Disordered Mesoscopic Systems"
I. L. Aleiner, B. L. Altshuler, M. E. Gershenson
In a recent paper, Phys. Rev. Lett. 81, 1074 (1998), Golubev and Zaikin (GZ) found that ``zero-point fluctuations of electrons'' contribute to the dephasing rate extracted from the…
Strong localization of electrons in quasi-one-dimensional conductors
Yu. B. Khavin, M. E. Gershenson, A. L. Bogdanov
We report on the experimental study of electron transport in sub-micron-wide ''wires'' fabricated from Si -doped GaAs. These quasi-one-dimensional (Q1D) conductors demonstrate t…
Decoherence and the Thouless Crossover in One-Dimensional Conductors
Yu. B. Khavin, M. E. Gershenson, A. L. Bogdanov
The temperature and magnetic-field dependences of the resistance of one-dimensional (1D) conductors have been studied in the vicinity of the Thouless crossover. We find that on the…
