Active Fourier Spectroscopy: From fixed sampling protocols to adaptive measurement
J. Schroeder, J. Schröder, S. Howard +5
Fourier-transform spectroscopy (FTS) is based on the Nyquist-Shannon theorem, which dictates a strict sampling protocol for the measurement of continuous signals. Here we introduce…
Molecular origin of blood-based infrared fingerprints
Liudmila Voronina, Cristina Leonardo, Johannes B. Mueller-Reif +8
Previous studies demonstrated that infrared absorption spectra of blood sera may help disease detection. For clinical translation of this approach, it is important to determine the…
Cooling phonons with phonons: acoustic reservoir-engineering with silicon-vacancy centers in diamond
K. V. Kepesidis, M. -A. Lemonde, A. Norambuena +2
We study a setup where a single negatively-charged silicon-vacancy center in diamond is magnetically coupled to a low-frequency mechanical bending mode and via strain to the high-f…
PT-symmetry breaking in the steady state of microscopic gain-loss systems
Kosmas V. Kepesidis, Thomas J. Milburn, Julian Huber +3
The phenomenon of PT (parity- and time-reversal) symmetry breaking is conventionally associated with a change in the complex mode spectrum of a non-Hermitian system that marks a tr…
Phonon Cooling and Lasing with Nitrogen-Vacancy Centers in Diamond
K. V. Kepesidis, S. D. Bennett, S. Portolan +2
We investigate the strain-induced coupling between a nitrogen-vacancy impurity and a resonant vibrational mode of a diamond nanoresonator. We show that under near-resonant laser ex…
The Bose-Hubbard model with localized particle losses
Kosmas Kepesidis, Michael J. Hartmann
We consider the Bose-Hubbard model with particle losses at one lattice site. For the non-interacting case, we find that half of the bosons of an initially homogeneous particle dist…
