Universal covariant quantum cloning circuits for qubit entanglement manipulation
Levente Szabo, Matyas Koniorczyk, Peter Adam +1
We consider the entanglement manipulation capabilities of the universal covariant quantum cloner or quantum processor circuit for quantum bits. We investigate its use for cloning a…
Change in the character of quasiparticles without gap collapse in a model of fractional quantum Hall effect
Csaba Toke, Jainendra K. Jain
It is commonly assumed in the studies of the fractional quantum Hall effect that the physics of a fractional quantum Hall state, in particular the character of its excitations, is…
Observation of Nonequilibrium Carrier Distribution in Ge, Si and GaAs by Terahertz-pump--Terahertz-probe Measurements
Janos Hebling, Matthias C. Hoffmann, Harold Y. Hwang +2
We compare the observed strong saturation of the free carrier absorption in n-type semiconductors at 300 K in the terahertz frequency range when single-cycle pulses with intensitie…
Absence of correlations in the QCD Dirac spectrum at high temperature
Tamas G. Kovacs
I propose a simple model of the distribution of the small eigenvalues of the QCD Dirac operator well above the finite temperature phase transition where chiral symmetry is restored…
THz-pump -- THz-probe spectroscopy of semiconductors at high field strengths
Matthias C. Hoffmann, Janos Hebling, Harold Y. Hwang +2
Pumping n-type GaAs and InSb with ultrafast THz pulses having intensities higher than 150 MW/cm2 shows strong free carrier absorption saturation at temperatures of 300 K and 200 K…
