General simulation method for quantum-sensing systems
Felix Riexinger, Mirco Kutas, Björn Haase +2
Quantum sensing encompasses highly promising techniques with diverse applications including noise-reduced imaging, super-resolution microscopy as well as imaging and spectroscopy i…
General simulation method for spontaneous parametric down- and parametric up-conversion experiments
Felix Riexinger, Mirco Kutas, Björn Haase +4
Spontaneous parametric down-conversion (SPDC) sources are an important technology for quantum sensing and imaging. We demonstrate a general simulation method, based on modeling fro…
Density profile of interacting Fermions in a one-dimensional optical trap
Stefan A. Soeffing, Sebastian Eggert, Michael Bortz
The density distribution of the one-dimensional Hubbard model in a harmonic trapping potential is investigated in order to study the effect of the confining trap. Strong superimpos…
Dynamics and decoherence in the central spin model using exact methods
Michael Bortz, Sebastian Eggert, Christian Schneider +2
The dynamics and decoherence of an electronic spin-1/2 qubit coupled to a bath of nuclear spins via hyperfine interactions in a quantum dot is studied. We show how exact results fr…
Spectrum and Screening cloud in the central spin model
Michael Bortz, Sebastian Eggert, Joachim Stolze
We consider an electronic spin in a quantum dot, coupled to the surrounding nuclear spins via inhomogeneous antiferromagnetic hyperfine interactions and subject to a uniform field,…
Lattice vs. continuum theory of the periodic Heisenberg chain
Michael Bortz, Michael Karbach, Imke Schneider +1
We consider the detailed structure of low energy excitations in the periodic spin-1/2 XXZ Heisenberg chain. By performing a perturbative calculation of the non-linear corrections t…
