Magnetic control of Coulomb scattering and terahertz transitions among excitons

J. Bhattacharyya, S. Zybell, F. Eßer +9

Time-resolved terahertz quenching studies of the magnetoexcitonic photoluminescence from GaAs/AlGaAs quantum wells are performed. A microscopic theory is developed to analyze the e…

Solar-energy conversion and light emission in an atomic monolayer p-n diode

Andreas Pospischil, Marco M. Furchi, Thomas Mueller

Two-dimensional (2D) atomic crystals, such as graphene and atomically thin transition metal dichalcogenides (TMDCs), are currently receiving a lot of attention. They are crystallin…

Towards Realizing a Quantum Memory for a Superconducting Qubit: Storage and Retrieval of quantum states

Shiro Saito, Xiaobo Zhu, Robert Amsüss +7

We have built a hybrid system composed of a superconducting flux qubit (the processor) and an ensemble of nitrogen-vacancy centers in diamond (the memory) that can be directly coup…

Ballistic Phonon Transport in Ultra-Thin Silicon Layers: Effects of Confinement and Orientation

Hossein Karamitaheri, Neophytos Neophytou, Hans Kosina

We investigate the effect of confinement and orientation on the phonon transport properties of ultra-thin silicon layers of thicknesses between 1 nm-16 nm. We employ the modified v…

Phonon Cooling and Lasing with Nitrogen-Vacancy Centers in Diamond

K. V. Kepesidis, S. D. Bennett, S. Portolan +2

We investigate the strain-induced coupling between a nitrogen-vacancy impurity and a resonant vibrational mode of a diamond nanoresonator. We show that under near-resonant laser ex…

Superconducting Circuits for Quantum Simulation of Dynamical Gauge Fields

D. Marcos, P. Rabl, E. Rico +1

We describe a superconducting-circuit lattice design for the implementation and simulation of dynamical lattice gauge theories. We illustrate our proposal by analyzing a one-dimens…
