Spin-Dependent Phenomena in Semiconductor Micro-and Nanoparticles—From Fundamentals to Applications

open access: yesApplied Sciences, 2020
The present overview of spin-dependent phenomena in nonmagnetic semiconductor microparticles (MPs) and nanoparticles (NPs) with interacting nuclear and electron spins is aimed at covering a gap between the basic properties of spin behavior in solid-state

Beyond theT1Limit: Singlet Nuclear Spin States in Low Magnetic Fields [PDF]

open access: yesPhysical Review Letters, 2004
Low-field nuclear spin singlet states may be used to store nuclear spin order in a room temperature liquid for a time much longer than the spin-lattice relaxation time constant T1. The low-field nuclear spin singlets are unaffected by intramolecular dipole-dipole relaxation, which is generally the predominant relaxation mechanism.

Nuclear conversion theory: molecular hydrogen in non-magnetic insulators [PDF]

open access: yesRoyal Society Open Science, 2016
The hydrogen conversion patterns on non-magnetic solids sensitively depend upon the degree of singlet/triplet mixing in the intermediates of the catalytic reaction. Three main ‘symmetry-breaking’ interactions are brought together.

Nuclear State Preparation via Landau-Zener-Stueckelberg transitions in Double Quantum Dots [PDF]

open access: yes, 2009
We theoretically model a nuclear-state preparation scheme that increases the coherence time of a two-spin qubit in a double quantum dot. The two-electron system is tuned repeatedly across a singlet-triplet level-anticrossing with alternating slow and ...

Magnetic excitations in an ionic spin-chain system with a nonmagnetic ferroelectric instability

open access: yesPhysical Review Research, 2020
Cross-correlation between magnetism and dielectric is expected to offer distinct emergent phenomena. Here, magnetic excitations in the organic donor-acceptor spin-chain system, tetrathiafulvalene-bromanil (TTF-BA), with a ferroelectric ground state is ...

Field-induced phase transitions of tetramer-singlet states in synthetic SU(4) magnets

open access: yesAIP Advances, 2021
Phase transitions of quantum dimer magnets can be explained in terms of Bose-Einstein condensation of magnons. Here we consider a natural extension of the dimer magnets to SU(4)-symmetric tetramer systems, which could be created with four nuclear-spin ...

Leading superconducting instabilities in three-dimensional models for Sr_{2}RuO_{4}

open access: yesPhysical Review Research, 2022
The unconventional superconductor Sr_{2}RuO_{4} has been the subject of enormous interest over more than two decades, but until now the form of its order parameter has not been explicitly determined. Since groundbreaking NMR experiments revealed recently

Rapid Single-Shot Measurement of a Singlet-Triplet Qubit [PDF]

open access: yes, 2009
We report repeated single-shot measurements of the two-electron spin state in a GaAs double quantum dot. The readout scheme allows measurement with fidelity above 90% with a 7 microsecond cycle time.
