Finite-temperature contact for a SU(2) Fermi gas trapped in a one-dimensional harmonic confinement
(American Physical Society, 2020-01)
We calculate the finite-temperature Tan's contact for N SU(2) fermions, characterized by repulsive contact interaction, trapped in a 1D harmonic confinement within a local density approximation on top of a thermodynamic ...
Analysis of canonical molecular orbitals to identify fermi contact coupling pathways. 1. Through-space transmission by overlap of 31P lone Pairs
(American Chemical Society, 2010-02)
In this work, a new approach to studying coupling pathways for the Fermi contact term of NMR spin-spin coupling constants (SSCCs) is presented. It is based on the known form of propagating the Fermi hole through a canonical ...
Hole states in diamond p-delta-doped field effect transistors
(IOP PUBLISHING, 2009)
The p-delta-doping in diamond allows to create high density two-dimensional hole gases. This technique has already been applied in the design and fabrication of diamond-based field effect transistors. Consequently, the ...
Quantum high-frequency conductivity oscillations in graphene multilayers and nodal semimetals in a tilted magnetic field
(Springer, 2017)
A new type of angular oscillations of the high-frequency conductivity for conductors with a band-contact line has been predicted. The effect is caused by groups of charge carriers near the self-intersection points of the ...
The effect of lone pairs and electronegativity on the indirect nuclear spin‐spin coupling constants in CH₂X (X=CH₂, NH, O, S): Ab initio calculations using optimized contracted basis sets
(American Institute of Physics, 2001-07)
The indirect nuclear spin–spin coupling constants of C₂H4, CH₂NH, CH₂O,CH₂O, and CH₂S were investigated by means of correlated ab initio calculations at the level of the second order polarization propagator approximation ...
Dynamical thermalization of interacting fermionic atoms in a sinai oscillator trap
(Multidisciplinary Digital Publishing Institute, 2019-08-08)
We study numerically the problem of dynamical thermalization of interacting cold fermionic atoms placed in an isolated Sinai oscillator trap. This system is characterized by a quantum chaos regime for one-particle dynamics. ...
Nonlinear optical properties in an asymmetric double δ‐doped quantum well with a Schottky barrier: Electric field effects
(Wiley, 2013-09)
The effect of an externally applied static electric field on the nonlinear optical response in a GaAs asymmetric double urn:x-wiley:15213951:media:pssb201350050:pssb201350050-math-0003‐doped quantum well is studied. The ...
NMR spin–spin coupling constants in hydrogen-bonded glycine clusters
(John Wiley & Sons Inc, 2018-08)
The influence of the hydrogen bond formation on the NMR spin–spin coupling constants (SSCC), including the Fermi contact (FC), the diamagnetic spin-orbit, the paramagnetic spin-orbit, and the spin dipole term, has been ...
NMR Spectroscopic Parameters of Molecular Systems with Strong Hydrogen Bonds
(American Chemical Society, 2010-07)
A series of closed H-bonded molecules that have (or not) delocalized bonds were studied. The dependence of both NMR spectroscopic parameters σ and J-couplings, and also the energy stability of such molecules with H-bond ...
Theoretical NMR nJ(13C,13C) Scalar Couplings as Probes to Study Diamagnetic Ring Currents in Fullerenes
(Elsevier Academic Press Inc., 2005-12)
In this work J(13C,13C) coupling constants and the principal components of nuclear magnetic shielding constants in the C60, C70, and Cð6KÞ 60 fullerenes are calculated at the B3LYP/cc-pCVDZ-sd level using optimized ...
