High temperature gate control of quantum well spin memory
O. Z. Karimov, G. H. John, R. T. Harley +4
Time-resolved optical measurements in (110)-oriented GaAs/AlGaAs quantum wells show a ten-fold increase of the spin-relaxation rate as a function of applied electric field from 20…
Accuracy of circular polarization as a measure of spin polarization in quantum dot qubits
C. E. Pryor, M. E. Flatté
A quantum dot spin LED provides a test of carrier spin injection into a qubit, as well as a means of analyzing carrier spin injection in general and local spin polarization. The po…
Electric field tunability of nuclear and electronic spin dynamics due to the hyperfine interaction in semiconductor nanostructures
Ionel Tifrea, Michael E. Flatte
We present formulas for the nuclear and electronic spin relaxation times due to the hyperfine interaction for nanostructed systems and show that the times depend on the square of t…
Local Electronic Structure of a Single Magnetic Impurity in a Superconductor
Michael E. Flatte', Jeff M. Byers
The electronic structure near a single classical magnetic impurity in a superconductor is determined using a fully self-consistent Koster-Slater algorithm. Localized excited states…
Theory of a Scanning Tunneling Microscope with a Two-Protrusion Tip
Michael E. Flatte', Jeff M. Byers
We consider a scanning tunneling microscope (STM) such that tunneling occurs through two atomically sharp protrusions on its tip. When the two protrusions are separated by at least…
Measuring the Relative Phase of the Energy Gap in a High-Temperature Superconductor with EELS
Michael E. Flatte'
A method of measuring the relative phase of the energy gap in a high-temperature superconductor is suggested for electron energy loss spectroscopy. Energy-resolved measurements of…
Probing Spatial Correlations with Nanoscale Two-Contact Tunneling
Jeff M. Byers, Michael E. Flatte'
Interference effects on the transport through two localized tunnel junctions on the surface of a well-grounded sample reveal intrinsic spatial correlations characteristic of the un…
Influence of Gap Extrema on the Tunneling Conductance Near an Impurity in an Anisotropic Superconductor
J. M. Byers, M. E. Flatte', D. J. Scalapino
Changes: figures added in postscript form, Eq. (7) and various typos corrected. We examine the effect of an impurity on the nearby tunneling conductance in an anisotropically-gappe…
Subharmonic Generation in Quantum Systems
Martin Holthaus, Michael E. Flatte'
We show how the classical-quantum correspondence permits long-lived subharmonic motion in a quantum system driven by a periodic force. Exponentially small deviations from exact sub…
Method for Measuring the Momentum-Dependent Relative Phase of the Superconducting Gap of High-Temperature Superconductors
M. E. Flatte', S. Quinlan, D. J. Scalapino
The phase variation of the superconducting gap over the (normal) Fermi surface of the high-temperature superconductors remains a significant unresolved question. Is the phase of th…
Lower Bound on the Energy Gap at Precise Locations on the Bi_2Sr_2CaCu_2O_8 Fermi Surface
Michael E. Flatte
Recent inelastic-neutron-scattering measurements of a low-energy phonon in Bi_2Sr_2CaCu_2O_8 provide enough information to place a lower bound on the energy gap magnitude at precis…
