Entanglement under equilibrium establishing in spin systems subjected to radiofrequency field
The method of the nonequilibrium statistical operator in a rotating frame is used to describe the evolution of the spin system and it is shown that the equilibrium establishment has nonexponential character, and the time needed for this establishment depends strongly on the RF field strength.
Investigations of nuclear antiferromagnetic ordering in copper at nanokelvin temperatures
Nuclear magnetism in metallic copper has been studied by demagnetizing highly polarized spins to low fields where spin-spin interactions dominate. In earlier experiments anomalous spin-lattice
Experimental determination of the critical temperature
2014 An experimental study of the magnetic ordering of the proton spin system in Ca(OH)2 is presented. The ordered phase is reached via dynamic nuclear polarization followed by an adiabatic
Evidence of spin-temperature in dynamic nuclear polarization: an exact computation of the EPR spectrum.
A numerical method is developed to compute exactly the EPR spectrum in the presence of dipolar interactions and shows the validity of the spin-temperature approach for typical radical concentration used in dissolution DNP protocols.
Thermalization and many-body localization in systems under dynamic nuclear polarization
We study the role of dipolar interactions in the standard protocol used to achieve dynamic nuclear polarization (DNP). In the so-called spin-temperature regime, where the interactions establish an
Quantum and Classical Correlations in the Solid-State NMR Free Induction Decay
The free induction decay (FID) of the transverse magnetization in a dipolar-coupled rigid lattice is a fundamental problem in magnetic resonance and in the theory of many-body systems. As it was
On the role of electron-nucleus contact and microwave saturation in thermal mixing DNP.
The likelihood of different scenarios is discussed in the light of the experimental data currently available in the literature, to point out which aspects are suitably accounted for and which are not by the declination of thermal mixing DNP considered here.
Dynamic Nuclear Polarization in Solids: The Birth and Development of the Many-Particle Concept
A brief review is presented on historical aspects of the dynamic nuclear polarization (DNP) research in 1960–1970s of the last century. Much attention is given to development of the many-particle
Nuclear-spin relaxation of 207 Pb in ferroelectric powders
The ²o⁷Pb nuclear system (nuclear spin I = 1/2; magnetic Moment μ ≈0.58 μN; isotopic abundance ≈ 22%) in ferroelectric solids has been proposed for a search for a Schiff moment associated with
