Detect Spinons via Spin Transport

, 2013
Existence of spinons is the defining property of quantum spin liquids. These exotic excitations have (fractionalized) spin quantum number and no electric charge, and have been proposed to form Fermi surfaces in the recently discovered organic spin liquid

Nitroxide-Based Contrast Agents for MRI Cancer Diagnostics: Progress, Limitations, and Perspectives

Molecules
Magnetic resonance imaging (MRI) is one of the most powerful non-invasive methods for cancer diagnostics. To enhance image contrast and, therefore, diagnostic accuracy, contrast agents (CAs) are widely used in clinics.

Circularly Polarized Resonant Rayleigh Scattering and Skyrmions in the $\nu$ = 1 Quantum Hall Ferromagnet

, 2011
We use the circularly polarized resonant Rayleigh scattering (RRS) to study the quantum Hall ferromagnet at $\nu$ = 1. At this filling factor we observe a right handed copolarized RRS which probes the Skyrmion spin texture of the electrons in the ...

Probing transverse quark polarization in deep-inelastic leptoproduction [PDF]

, 1995
The azimuthal dependence of hadrons produced in lepton scattering off a polarized hadron probes the quark transverse-spin distributions. In the calculation of the asymmetries, transverse momenta of quarks in the distribution and fragmentation functions ...

Chiral properties of tetrathiatriarylmethyl spin probes

Chemical Communications, 2011
We report that tetrathiatriarylmethyl (trityl) EPR probes are chiral molecules at room temperature, the two stereoisomers that differ in their helicity being configurationally stable enough to be separated and stored independently.

Sensitivity of a collisional single-atom spin probe

SciPost Physics Core, 2023
We study the sensitivity of a collisional single-atom probe for ultracold gases. Inelastic spin-exchange collisions map information about the gas temperature $T$ or external magnetic field $B$ onto the quantum spin-population of single-atom probes, and ...

Theory of Raman response in three-dimensional Kitaev spin liquids: application to $\beta-$ and $\gamma-$Li$_2$IrO$_3$ compounds

, 2015
We calculate the Raman response for the Kitaev spin model on the $\mathcal{H}$-$0$, $\mathcal{H}$-$1$, and $\mathcal{H}$-$\infty$ harmonic honeycomb lattices.

Electron-nuclear coherent spin oscillations probed by spin-dependent recombination [PDF]

Physical Review B, 2018
We demonstrate the detection of coherent electron-nuclear spin oscillations related to the hyperfine interaction and revealed by the band-to-band photoluminescence (PL) in zero external magnetic field. On the base of a pump-probe PL experiment we measure, directly in the temporal domain, the hyperfine constant of an electron coupled to a gallium defect

Electron Paramagnetic Resonance Study of Pulsed Electric Field-Assisted Internalization of Spin Probes into Yeast Cells

Applied Sciences
Efficient internalization of chemical entities into cells across the plasma membrane barrier is crucial for most biomedical applications. Among the physical factors that can enhance the delivery of active substances, the electric field plays an important

Dependence of current-induced switching threshold on composition gradient width in Si/Al-integrated perpendicular magnetic films [PDF]

AIP Advances
We report spin–orbit torque switching in perpendicularly magnetized Pt(3.1 nm)/Co(0.95 nm)/Pt(3.1 nm) trilayer using Si/Al composition-graded materials (CGMs).
