Single exciton emission from gate-defined quantum dots
G. J. Schinner, J. Repp, E. Schubert +6
With gate-defined electrostatic traps fabricated on a double quantum well we are able to realize an optically active and voltage-tunable quantum dot confining individual, long-livi…
Many-body correlations of electrostatically trapped dipolar excitons
G. J. Schinner, J. Repp, E. Schubert +6
We study the photoluminescence (PL) of a two-dimensional liquid of oriented dipolar excitons in In_{x}Ga_{1-x}As coupled double quantum wells confined to a microtrap. Generating ex…
TRIGA-SPEC: A setup for mass spectrometry and laser spectroscopy at the research reactor TRIGA Mainz
J. Ketelaer, J. Krämer, D. Beck +17
The research reactor TRIGA Mainz is an ideal facility to provide neutron-rich nuclides with production rates sufficiently large for mass spectrometric and laser spectroscopic studi…
Demonstration of a Multiplexing Trapped Ion Quantum Processing Unit
F. Anmasser, M. Abu Zahra, K. Schüppert +9
A fault-tolerant quantum computer is expected to require thousands of qubits. Trapped ion architectures provide a modular approach where the quantum register is divided into multip…
PENTATRAP: A novel cryogenic multi-Penning trap experiment for high-precision mass measurements on highly charged ions
J. Repp, Ch. Böhm, J. R. Crespo López-Urrutia +9
The novel five-Penning trap mass spectrometer PENTATRAP is developed at the Max-Planck-Institut für Kernphysik (MPIK), Heidelberg. Ions of interest are long-lived highly charged n…
Scanning tunneling microscopy and spectroscopy of sodium-chloride overlayers on the stepped Cu(311) surface: Experimental and theoretical study
F. E. Olsson, M. Persson, J. Repp +1
The physical properties of ultrathin NaCl overlayers on the stepped Cu(311) surface have been characterized using scanning tunneling microscopy (STM) and spectroscopy, and density…
