On the lower bound of the refined Bessis--Moussa--Villani conjecture: proof of the cases S_{6,3} and S_{7,3} for 3x3 matrices
Daniel Hägele
For Hermitian matrices let $\A_{n,m}(e^α,e^β)$ be the average of the traces of all words with letters and letters . The refined Bessis--Moussa--Villani con…
Simultaneous direct measurement of the electrocaloric and dielectric dynamics of ferroelectrics with microsecond temporal resolution
J. Fischer, J. Döntgen, C. Molin +6
A contactless technique for direct time-resolved measurements of the full dynamics of the adiabatic temperature change in electrocaloric materials is introduced. The infrared radia…
Random-time quantum measurements
Markus Sifft, Daniel Hägele
The analysis of a continuous measurement record poses a fundamental challenge in quantum measurement theory. Different approaches have been used in the past as records can,…
Higher order moments, cumulants, and spectra of continuous quantum noise measurements
Daniel Hägele, Fabian Schefczik
We present general quantum mechanical expressions for higher order moments, cumulants, and spectra of continuously measured quantum systems with applications in spin noise spectros…
Electron spin orientation under in-plane optical excitation in GaAs quantum wells
S. Pfalz, R. Winkler, N. Ubbelohde +2
We study the optical orientation of electron spins in GaAs/AlGaAs quantum wells for excitation in the growth direction and for in-plane excitation. Time- and polarization-resolved…
