Electron spin resonance in a proximity-coupled MoS2/graphene van der Waals heterostructure

AIP Advances, 2022
Coupling graphene’s excellent electron and spin transport properties with a higher spin–orbit coupling (SOC) material allows tackling the hurdle of spin manipulation in graphene due to the proximity to van der Waals layers. Here, we use magneto-transport

The effect of spin polarization on double electron–electron resonance (DEER) spectroscopy [PDF]

Magnetic Resonance, 2022
Double electron–electron resonance (DEER) spectroscopy measures the distribution of distances between two electron spins in the nanometer range, often on doubly spin-labeled proteins, via the modulation of a refocused spin echo by the dipolar interaction

Chemical compass behaviour at microtesla magnetic fields strengthens the radical pair hypothesis of avian magnetoreception

Nature Communications, 2019
Many animals use the Earth’s magnetic field for orientation, yet the underlying principles are poorly understood. The authors show that a molecular triad acts as a chemical compass in magnetic fields of similar magnitude to that of the Earth, supporting ...

A facile approach for the in vitro assembly of multimeric membrane transport proteins

eLife, 2018
Membrane proteins such as ion channels and transporters are frequently homomeric. The homomeric nature raises important questions regarding coupling between subunits and complicates the application of techniques such as FRET or DEER spectroscopy.

Coherent state transfer between an electron and nuclear spin in (15)N@C(60). [PDF]

, 2011
Electron spin qubits in molecular systems offer high reproducibility and the ability to self-assemble into larger architectures. However, interactions between neighboring qubits are "always on," and although the electron spin coherence times can be ...

On the Electron Spin Resonances in DNA

Biophysical Journal, 1963
Iron impurities are shown to account for characteristic electron spin resonances observed in samples of DNA. Comparative e.s.r. measurements on lyophilized samples were done in conjunction with static susceptibility measurements, trace analyses, and molecular degradation experiments to establish this correlation.

Constructive quantum interference in a bis-copper six-porphyrin nanoring

Nature Communications, 2017
Quantum interference in charge transport is attracting interest with applications in nanoelectronics and quantum computing. Here, the authors present a method for quantifying electronic transmission through molecules, and demonstrate constructive quantum

chiLife: An open-source Python package for in silico spin labeling and integrative protein modeling.

PLoS Computational Biology, 2023
Here we introduce chiLife, a Python package for site-directed spin label (SDSL) modeling for electron paramagnetic resonance (EPR) spectroscopy, in particular double electron-electron resonance (DEER).

Flopping-mode electric dipole spin resonance

Physical Review Research, 2020
Traditional approaches to controlling single spins in quantum dots require the generation of large electromagnetic fields to drive many Rabi oscillations within the spin coherence time. We demonstrate “flopping-mode” electric dipole spin resonance, where
