Nuclear magnetic resonance study of fluorine–graphite intercalation compounds and graphite fluorides

TL;DR: In this article, a review of the NMR investigations of graphite fluorides and fluorine-graphite intercalation compounds is presented, where the origin of semimetal metal and metal-insulator transformations, localization effects and C-F bonding in fluorine graphite intercation compounds are discussed.
Journal ArticleDOI

Quantum-to-classical Transition of Cosmological Perturbations for Non-vacuum Initial States

TL;DR: In this paper, the authors show that the Wigner function is not everywhere positive for any finite rk, hence its interpretation as a classical distribution function in phase space is impossible without some coarse graining procedure.
Journal ArticleDOI

Electronic Hamiltonian, wave functions, and energies, and derivative coupling between Born–Oppenheimer states in the vicinity of a conical intersection

TL;DR: In this article, the authors derived the first terms of the power series expansion of the electronic Hamiltonian in the neighborhood of the conical intersection at the equilateral triangle configuration of the homonuclear triatomic system M3.
Journal ArticleDOI

Chiral electron transport: scattering through helical potentials.

TL;DR: A model for the transmission of spin-polarized electrons through oriented chiral molecules, where the chiral structure is represented by a helix, which can be easily extended to the Landauer regime of conductance where conductance is due to elastic scattering, so that the conductance of chiral molecular junctions is considered.
Journal ArticleDOI

Microscopic origins of irreversible macroscopic behavior

TL;DR: The second law of thermodynamics is observed in individual macroscopic systems as discussed by the authors, and it can be understood as arising naturally from time-symmetric microscopic laws in accord with the ideas of Thompson, Maxwell and Boltzmann.
