The static and the dynamic spin correlations in the low-temperature collapsed tetragonal and the hightemperature tetragonal phase in CaFe2As2 have been investigated by As75 nuclear magnetic resonance (NMR) and nuclear quadrupole resonance (NQR) measurements. Through the temperature (T) dependence of the nuclear spin lattice relaxation rates (1/T1) and the Knight shifts, although stripe-type ant...

A novel theory of consciousness is proposed in this paper. We postulate that consciousness is intrinsically connected to quantum spin since the latter is the origin of quantum effects in both Bohm and Hestenes quantum formulism and a fundamental quantum process associated with the structure of space-time. That is, spin is the "mind-pixel". The unity of mind is achieved by entanglement of the mi...

We study theoretically the formation of nuclear-spin polaron state in semiconductor nanosystems within Lindblad equation approach. To this end, we derive a general for density operator that complies with symmetry system Hamiltonian and address localized charge carriers subject to an arbitrarily anisotropic hyperfine interaction when optically cooling nuclei. The steady-state solution matrix cen...

This talk will illustrate the benefits offered by QIP with two devices which use quantum entanglement among nuclear spins to perform high-precision measurements: (1) a spin gyroscope that operates by detecting the frequency shift in the spins precession rate in the rotating frame, which is potentially more accurate than mechanical or optical devices; (2) a quantum amplifier which correlates the...
