Spin physics highlights from STAR

open access: yesEPJ Web of Conferences, 2015
As the world’s only polarized proton collider, the Relativistic Heavy Ion Collider (RHIC) at Brookhaven plays an important role in understanding the spin structure of the proton.

2-Butyl-2-tert-butyl-5,5-diethylpyrrolidine-1-oxyls: Synthesis and Properties

open access: yesMolecules, 2020
Nitroxides are broadly used as molecular probes and labels in biophysics, structural biology, and biomedical research. Resistance of a nitroxide group bearing an unpaired electron to chemical reduction with low-molecular-weight antioxidants and enzymatic

Frequency estimation under non-Markovian spatially correlated quantum noise

open access: yesNew Journal of Physics, 2022
We study the estimation precision attainable by entanglement-enhanced Ramsey interferometry in the presence of spatiotemporally correlated non-classical noise.

Background removal from rapid-scan EPR spectra of nitroxide-based spin labels by minimizing non-quadratic cost functions

open access: yesJournal of Magnetic Resonance Open, 2023
Rapid-scan electron paramagnetic resonance spectroscopy is an emerging technique which substantially improves the signal-to-noise ratio and time resolution compared to conventional continuous-wave experiments.

In-gap impurity states as the hallmark of the Quantum Spin Hall phase [PDF]

open access: yes, 2012
We study the different response to an impurity of the two topologically different phases shown by a two dimensional insulator with time reversal symmetry, namely, the Quantum Spin Hall and the normal phase. We consider the case of graphene as a toy model

Strain-Induced Spin-Nematic State and Nematic Susceptibility Arising from 2×2 Fe Clusters in KFe_{0.8}Ag_{1.2}Te_{2}. [PDF]

open access: yes, 2019
Spin nematics break spin-rotational symmetry while maintaining time-reversal symmetry, analogous to liquid crystal nematics that break spatial rotational symmetry while maintaining translational symmetry.

New Developments in Spin Labels for Pulsed Dipolar EPR

open access: yesMolecules, 2014
Spin labelling is a chemical technique that enables the integration of a molecule containing an unpaired electron into another framework for study. Given the need to understand the structure, dynamics, and conformational changes of biomacromolecules ...

Nanometre-scale probing of spin waves using single electron spins [PDF]

open access: yesNature Communications, 2015
AbstractPushing the frontiers of condensed-matter magnetism requires the development of tools that provide real-space, few-nanometre-scale probing of correlated-electron magnetic excitations under ambient conditions. Here we present a practical approach to meet this challenge, using magnetometry based on single nitrogen-vacancy centres in diamond.

Room temperature magneto-optic effect in silicon light-emitting diodes

open access: yesNature Communications, 2018
Silicon is an important material in spintronics but its inefficiency in light emission limits the optical probes for spin transport. Here Chiodi et al.

Quantum entangled-probe scattering theory

open access: yesNew Journal of Physics, 2021
We develop an entangled-probe scattering theory, including quantum detection, that extends the scope of standard scattering approaches. We argue that these probes may be revolutionary in studying entangled matter such as unconventional phases of strongly
