Quantum theory for phonon lasing and non-classical state generation in mixed-species and single trapped ions
David Baur, Tanja Behrle, Ivan Rojkov +4
In this article we present a comprehensive theoretical investigation of phonon lasing with mixed-species trapped ions, as demonstrated in [T. Behrle, Phys. Rev. Lett. 131 (2023)],…
Continuous-wave nitrogen-vacancy diamond laser system assisted by a red diode laser
Lukas Lindner, Felix A. Hahl, Tingpeng Luo +9
Diamond has long been identified as a potential host material for laser applications. This potential arises due to its exceptional thermal properties, ultra-wide bandgap, and color…
Proximal nitrogen reduces the fluorescence quantum yield of nitrogen-vacancy centres in diamond
Marco Capelli, Lukas Lindner, Tingpeng Luo +10
The nitrogen-vacancy colour centre in diamond is emerging as one of the most important solid-state quantum systems. It has applications to fields including high-precision sensing,…
Creation of nitrogen-vacancy centers in chemical vapor deposition diamond for sensing applications
T. Luo, L. Lindner, J. Langer +12
The nitrogen-vacancy (NV) center in diamond is a promising quantum system for magnetometry applications exhibiting optical readout of minute energy shifts in its spin sub-levels. K…
Magnetic-Field-Dependent Stimulated Emission from Nitrogen-Vacancy Centres in Diamond

Negatively charged nitrogen-vacancy centres in diamond are promising quantum magnetic field sensors. Laser threshold magnetometry has been a theoretical approach for the improvemen…
Absorptive laser threshold magnetometry: combining visible diamond Raman lasers and nitrogen-vacancy centres
Sarath Raman Nair, Lachlan J. Rogers, David J. Spence +5
We propose a high-sensitivity magnetometry scheme based on a diamond Raman laser with visible pump absorption by an ensemble of coherently microwave driven negatively charged nitro…
Amplification by stimulated emission of nitrogen vacancy centres in a diamond-loaded fibre cavity
Sarath Raman Nair, Lachlan J. Rogers, Xavier Vidal +7
Laser-threshold magetometry using the negatively charged nitrogen-vacancy (NV-) centre in diamond as a gain medium has been proposed as a technique to dramatically enhance the sens…
The effects of thermal and correlated noise on magnons in a quantum ferromagnet
Jan Jeske, Ángel Rivas, Muhammad H. Ahmed +2
The dynamics and thermal equilibrium of spin waves (magnons) in a quantum ferromagnet as well as the macroscopic magnetisation are investigated. Thermal noise due to an interaction…
Optical Cryocooling of Diamond
M. Kern, J. Jeske, D. M. W. Lau +3
The cooling of solids by optical means only using anti-Stokes emission has a long history of research and achievements. Such cooling methods have many advantages ranging from no-mo…
Signatures of spatially correlated noise and non-secular effects in two-dimensional electronic spectroscopy
James Lim, David J. Ing, Joachim Rosskopf +4
We investigate how correlated fluctuations affect oscillatory features in rephasing and non-rephasing two-dimensional (2D) electronic spectra of a model dimer system. Based on a be…
Stimulated emission from NV centres in diamond
Jan Jeske, Desmond W. M. Lau, Liam P. McGuinness +8
Stimulated emission is the process fundamental to laser operation, thereby producing coherent photon output. Despite negatively-charged nitrogen-vacancy (NV) centres being disc…

Muhammad H. Ahmed, Jan Jeske, Andrew D. Greentree
Magnonics is an emerging field with potential applications in classical and quantum information processing. Freely propagating magnons in two-dimensional media suffer from dispersi…
Dark state adiabatic passage with branched networks and high-spin systems: spin separation and entanglement
Caitlin Batey, Jan Jeske, Andrew D. Greentree
Adiabatic methods are potentially important for quantum information protocols because of their robustness against many sources of technical and fundamental noise. They are particul…

Jan Jeske, Jared H. Cole, Susana Huelga
Environmental noise can hinder the metrological capabilities of entangled states. While the use of entanglement allows for Heisenberg-limited resolution, the largest permitted by q…
Derivation of Markovian master equations for spatially correlated decoherence
Jan Jeske, Jared H. Cole
We introduce a general formalism to describe the effects of Markovian noise which is spatially correlated, typically decaying over some finite correlation length. For any system of…
