Optimization strategies for modulation transfer spectroscopy applied to laser stabilization
Tilman Preuschoff, Malte Schlosser, Gerhard Birkl
We present a general analysis for determining the optimal modulation parameters for the modulation transfer spectroscopy scheme. The results are universally valid and can be applie…
Resistive cooling of highly charged ions in a Penning trap to a fluid-like state
M. S. Ebrahimi, Z. Guo, M. Vogel +3
We have performed a detailed experimental study of resistive cooling of large ensembles of highly charged ions such as Ar in a cryogenic Penning trap. Different from the me…
Optically transparent solid electrodes for precision Penning traps
M. Wiesel, G. Birkl, M. S. Ebrahimi +4
We have conceived, built, and operated a cryogenic Penning trap with an electrically conducting yet optically transparent solid electrode. The trap, dedicated to spectroscopy and i…
Rapid crystallization of externally produced ions in a Penning trap
T. Murboeck, S. Schmidt, G. Birkl +3
We have studied the cooling dynamics, formation process and geometric structure of mesoscopic crystals of externally produced magnesium ions in a Penning trap. We present a cooling…
Blue-detuned optical ring trap for Bose-Einstein condensates based on conical refraction
A. Turpin, J. Polo, Yu. V. Loiko +6
We present a novel approach for the optical manipulation of neutral atoms in annular light structures produced by the phenomenon of conical refraction occurring in biaxial optical…
Coherent injecting, extracting, and velocity filtering of neutral atoms in a ring trap via spatial adiabatic passage
Yurii Loiko, Veronica Ahufinger, Ricard Menchon-Enrich +2
We introduce here a coherent technique to inject, extract, and velocity filter neutral atoms in a ring trap coupled via tunneling to two additional waveguides. By adiabatically fol…
