Negative-Parity Baryons in Quenched Anisotropic Lattice QCD

open access: yes, 2003
We study negative-parity baryon spectra in quenched anisotropic lattice QCD. The negative-parity baryons are measured as the parity partner of the ground-state baryons.

Modeling the singlet state with local variables [PDF]

open access: yesPhysics Letters A, 1999
A local-variable model yielding the statistics from the singlet state is presented for the case of inefficient detectors and/or lowered visibility. It has independent errors and the highest efficiency at perfect visibility is 77.80%, while the highest visibility at perfect detector-efficiency is 63.66%. Thus, the model cannot be refuted by measurements

Theory of Primary Photoexcitations in Donor-Acceptor Copolymers

open access: yes, 2015
We present a generic theory of primary photoexcitations in low band gap donor-acceptor conjugated copolymers. Because of the combined effects of strong electron correlations and broken symmetry, there is considerable mixing between a charge-transfer ...

Low-energy parameters of neutron-neutron scattering [PDF]

open access: yesЯдерна фізика та енергетика, 2013
The influence of the mass difference between charged and neutral -mesons on the low-energy parameters of nucleon-nucleon interaction in the spin-singlet state is studied.

Long live the singlet state!

open access: yesJournal of Magnetic Resonance, 2019
The field of long-lived states in NMR is reviewed. The relationship of long-lived-state phenomena to those associated with spin isomerism is discussed. A brief overview is given of key developments in the field of long-lived states, including chemical symmetry-switching, the role of magnetic equivalence and magnetic inequivalence, long-lived coherences,

Half-Integral Spin-Singlet Quantum Hall Effect

open access: yes, 1993
We provide numerical evidence that the ground state of a short range interaction model at $\nu=1/2$ is incompressible and spin-singlet for a wide range of repulsive interactions.

Superconductivity in a multiorbital model for the Γ3 crystalline electric field state

open access: yesAIP Advances, 2018
Superconductivity in a three-orbital model for the Γ3 crystalline electric field (CEF) ground state is investigated by applying the random phase approximation.
