Selective Dynamic Nuclear Spin Polarization in Spin-Blocked Double-Dot
, 2004 We study the mechanism of dynamical nuclear spin polarization by hyperfine interaction in spin-blocked double quantum dot system. We calculate the hyperfine transition rates and solve the master equations for the nuclear spins.

Experiments towards quantum information with trapped Calcium ions
, 2000 Ground state cooling and coherent manipulation of ions in an rf-(Paul) trap is the prerequisite for quantum information experiments with trapped ions. With resolved sideband cooling on the optical S1/2 - D5/2 quadrupole transition we have cooled one and ...

Interrelations between the pairing and quadrupole interactions in the microscopic Shell Model
EPJ Web of Conferences, 2016 We explore the dynamical symmetries of the shell model number conserving algebra, which define three types of pairing and quadrupole phases, with the aim to obtain the prevailing phase or phase transition for the real nuclear systems in a single shell ...

The magnetic quadrupole transition in neutral strontium
, 2022 Analog quantum simulators enable the experimental investigation of strongly interacting quantum many-body systems, for which numerical calculations are often out of reach for classical computers. One remarkably successful invention in the development of these simulators is the quantum gas microscope. These high-numerical-aperture microscopes enable the
