Absorption Spectrum of a Two-Level System Subjected to a Periodic Pulse Sequence
H. F. Fotso, V. V. Dobrovitski
We investigate how the quantum control of a two-level system (TLS) coupled to photons can modify and tune the TLS's photon absorption spectrum. Tuning and controlling the emission…
Suppressing Spectral Diffusion of the Emitted Photons with Optical Pulses
H. F. Fotso, A. E. Feiguin, D. D. Awschalom +1
In many quantum architectures the solid-state qubits, such as quantum dots or color centers, are interfaced via emitted photons. However, the frequency of photons emitted by solid-…
Comparison of dynamical decoupling protocols for a nitrogen-vacancy center in diamond
Zhi-Hui Wang, G. de Lange, D. Riste +2
We perform a detailed theoretical-experimental study of the dynamical decoupling (DD) of the nitrogen-vacancy (NV) center in diamond. We investigate the DD sequences applied to sup…
Decay of Rabi oscillations by dipolar-coupled dynamical spin environments
V. V. Dobrovitski, A. E. Feiguin, R. Hanson +1
We investigate the Rabi oscillations decay of a spin decohered by a spin bath whose internal dynamics is caused by dipolar coupling between the bath spins. The decay form and rate…
Correlation effects in the electronic structure of Mn molecular magnet
D. W. Boukhvalov, L. I. Vergara, V. V. Dobrovitski +5
We present joint theoretical-experimental study of the correlation effects in the electronic structure of (pyH)[MnOCl(OAc)]2MeCN molecular magnet (Mn…
Electronic structure of magnetic molecules V15: LDA+U calculations, X-ray emission and photoelectron spectra
D. W. Boukhvalov, E. Z. Kurmaev, A. Moewes +10
Electronic structure of V magnetic molecules (K [V As O (HO)] \cdot 8HO)$ has been studied using LSDA+U band structure calculations, and measur…
