Multirate characterization of relaxation mechanisms for two nonequivalent nuclear spins 1/2 in a liquid using maximally entangled pseudo-pure quantum states
Georgiy Baroncha, Alexander Perepukhov, Boris V. Fine
Multirate characterization of spin responses in nuclear magnetic resonance (NMR) is a promising approach to fingerprinting complex molecules in the presence of multiple relaxation…
Classical periodic trajectories and quantum scars in many-spin systems
Igor Ermakov, Oleg Lychkovskiy, Boris V. Fine
We numerically investigate the stability of exceptional periodic classical trajectories in rather generic chaotic many-body systems and explore a possible connection between these…
Relaxation of maximally entangled quantum states of two nonequivalent nuclear spins in a liquid
Georgiy Baroncha, Alexander Perepukhov, Boris V. Fine
We investigate both experimentally and theoretically the relaxation of pseudo-pure maximally entangled states (Bell states) of two nuclear spins 1H-13C belonging to a molecule in a…
Chaotic properties of spin lattices near second-order phase transitions
A. S. de Wijn, B. Hess, B. V. Fine
We perform a numerical investigation of the Lyapunov spectra of chaotic dynamics in lattices of classical spins in the vicinity of second-order ferromagnetic and antiferromagnetic…
Lyapunov instabilities in lattices of interacting classical spins at infinite temperature
A. S. de Wijn, B. Hess, B. V. Fine
We numerically investigate Lyapunov instabilities for one-, two- and three-dimensional lattices of interacting classical spins at infinite temperature. We obtain the largest Lyapun…
Largest Lyapunov exponents for lattices of interacting classical spins
A. S. de Wijn, B. Hess, B. V. Fine
We investigate how generic the onset of chaos in interacting many-body classical systems is in the context of lattices of classical spins with nearest neighbor anisotropic coupling…
