Mapping of the unoccupied states and relevant bosonic modes via the time dependent momentum distribution
A. F. Kemper, M. Sentef, B. Moritz +4
The unoccupied states of complex materials are difficult to measure, yet play a key role in determining their properties. We propose a technique that can measure the unoccupied sta…
Lieb's Theorem and Maximum Entropy Condensates
J. Tindall, F. Schlawin, M. Sentef +1
Coherent driving has established itself as a powerful tool for guiding a many-body quantum system into a desirable, coherent non-equilibrium state. A thermodynamically large system…
Correlation tuned cross-over between thermal and nonthermal states following ultrafast transient pumping
B. Moritz, A. F. Kemper, M. Sentef +2
We examine electron-electron mediated relaxation following excitation of a correlated system by an ultrafast electric field pump pulse. The results reveal a dichotomy in the tempor…
Doping Evolution of Oxygen K-edge X-ray Absorption Spectra in Cuprate Superconductors
C. -C. Chen, M. Sentef, Y. F. Kung +5
We study oxygen K-edge x-ray absorption spectroscopy (XAS) and investigate the validity of the Zhang-Rice singlet (ZRS) picture in overdoped cuprate superconductors. Using large-sc…
Focussing quantum states
M. Sentef, A. P. Kampf, S. Hembacher +1
Does the size of atoms present a lower limit to the size of electronic structures that can be fabricated in solids? This limit can be overcome by using devices that exploit quantum…
