On the torque on birefringent plates induced by quantum fluctuations
Davide Iannuzzi, Jeremy N. Munday, Yuri Barash +1
We present detailed numerical calculations of the mechanical torque induced by quantum fluctuations on two parallel birefringent plates with in plane optical anisotropy, separated…
Spin gap in the 2D electron system of GaAs/AlGaAs single heterojunctions in weak magnetic fields
V. S. Khrapai, A. A. Shashkin, E. L. Shangina +4
We study the interaction-enhanced spin gaps in the two-dimensional electron gas confined in GaAs/AlGaAs single heterojunctions subjected to weak magnetic fields. The values are obt…
Pauli spin susceptibility of a strongly correlated two-dimensional electron liquid
A. A. Shashkin, S. Anissimova, M. R. Sakr +3
Thermodynamic measurements reveal that the Pauli spin susceptibility of strongly correlated two-dimensional electrons in silicon grows critically at low electron densities - behavi…
Thermally Assisted Flux Flow in MgB2 : Strong Magnetic Field Dependence of the Activation Energy
A. Sidorenko, V. Zdravkov, V. Ryazanov +6
The origin of the resistive transition broadening for MgB2 thin films was investigated. Thermally activated flux flow is found to be responsible for the resistivity contribution in…
Microwave Properties of Ba(0.6)K(0.4)BiO(3) Crystals
S. Fricano, M. Bonura, A. Agliolo Gallitto +3
We report on field-induced variations of the microwave surface resistance at 9.6 GHz of Ba(0.6)K(0.4)BiO(3) crystals. Energy losses have been investigated as a function of the stat…
