Field and frequency modulated sub-THz electron spin resonance spectrometer

APL Photonics, 2016
260-GHz radiation is used for a quasi-optical electron spin resonance (ESR) spectrometer which features both field and frequency modulation. Free space propagation is used to implement Martin-Puplett interferometry with quasi-optical isolation, mirror ...

Electron spin dynamics during microwave pulses studied by 94 GHz chirp and phase-modulated EPR experiments [PDF]

Magnetic Resonance
Electron spin dynamics during microwave irradiation are of increasing interest in electron paramagnetic resonance (EPR) spectroscopy, as locking electron spins into a dressed state finds applications in EPR and dynamic nuclear polarization (DNP ...

High-spin Metal Centres in Dipolar EPR Spectroscopy

CHIMIA, 2018
The substitution of Mg2+ by Mn2+ in the bacterial DnaB helicase from Helicobacter pylori, an ATP:Mg2+-fuelled protein engine, allows electron paramagnetic resonance (EPR) spectroscopy to be performed on this system.

Revealing the Electron-Spin Fluctuation Coupling by Photoemission in CaKFe_{4}As_{4}

Physical Review X
Electron-boson coupling in unconventional superconductors is one of the key parameters in understanding the superconducting pairing symmetry. Here, we report definitive photoemission evidence of electron-spin fluctuation coupling in the iron-based ...

Spin Polarization Oscillations without Spin Precession: Spin-Orbit Entangled Resonances in Quasi-One-Dimensional Spin Transport

Physical Review X, 2014
Resonant behavior involving spin-orbit entangled states occurs for spin transport along a narrow channel defined in a two-dimensional electron gas, including an apparent rapid relaxation of the spin polarization for special values of the channel width ...

Cavity-Mediated Entanglement of Parametrically Driven Spin Qubits via Sidebands

PRX Quantum
We consider a pair of quantum dot-based spin qubits that interact via microwave photons in a superconducting cavity and that are also parametrically driven by separate external electric fields.
