Frequency splitting of intervalley phonons in graphene
K. Ziegler, E. Kogan
We study the thermal distribution of intervalley phonons in a graphene sheet. These phonons have two components with the same frequency. The degeneracy of the two modes is preserve…
Direct observation of dynamic surface acoustic wave controlled carrier injection into single quantum posts using phase-resolved optical spectroscopy
S. Völk, F. Knall, F. J. R. Schülein +5
A versatile stroboscopic technique based on active phase-locking of a surface acoustic wave to picosecond laser pulses is used to monitor dynamic acoustoelectric effects. Time-inte…
Recent progress towards acoustically mediated carrier injection into individual nanostructures for single photon generation
Stefan Völk, Florian J. R. Schülein, Florian Knall +12
We report on recent progress towards single photon sources based on quantum dot and quantum post nanostructures which are manipulated using surface acoustic waves. For this concept…
Enhanced sequential carrier capture into individual quantum dots and quantum posts controlled by surface acoustic waves
Stefan Völk, Florian J. R. Schülein, Florian Knall +7
Individual self-assembled Quantum Dots and Quantum Posts are studied under the influence of a surface acoustic wave. In optical experiments we observe an acoustically induced switc…
Markovian embedding of fractional superdiffusion
P. Siegle, I. Goychuk, P. Hanggi
The Fractional Langevin Equation (FLE) describes a non-Markovian Generalized Brownian Motion with long time persistence (superdiffusion), or anti-persistence (subdiffusion) of both…
Quantum-noise quenching in atomic tweezers
Stefano Zippilli, Bernd Mohring, Eric Lutz +2
The efficiency of extracting single atoms or molecules from an ultracold bosonic reservoir is theoretically investigated for a protocol based on lasers, coupling the hyperfine stat…
