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…
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…
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…
