SINGLET GROUND STATE MAGNETISM
Le Journal de Physique Colloques, 1971 We discuss the magnetic behavior of rare earth systems where the crystal-field-only ground state of the rare earth ion is a singlet. As exchange increases in such a system, magnetic ordering at zero temperature occurs through a polarization instability of the singlet ground state.

Determination of singlet oxygen quenching rate and mechanism of γ-oryzanol
Heliyon, 2021 Photooxidation is one of the causes of quality deterioration in food. An antioxidant or singlet oxygen quencher is urgently needed to prevent photooxidation. γ-Oryzanol was recognized as a naturally present antioxidant in rice bran products.

Wave function of the sexaquark or compact H-dibaryon
Journal of High Energy Physics, 2023 We derive and explicitly display the internal wave function of a color-, flavor- and spin- singlet dibaryon composed of uuddss quarks in a spatially symmetric state, in the approximation of exact SU(3) flavor symmetry.

Unveiling the concentration dependent direct triplet formation via singlet fission in a tetracene derivative [PDF]
EPJ Web of Conferences, 2019 Singlet fission is slowed down on diffusional timescales in highly concentrated solutions compared to thin films for a tetracene-like molecule. The underlying mechanism suggests competing intersystem crossing and singlet fission, where in the latter ...

Dissociative Autoionization in (1+2)-photon Above Threshold Excitation of H2 Molecules [PDF]
, 1999 We have theoretically studied the effect of dissociative autoionization on the photoelectron energy spectrum in (1+2)-photon above threshold ionization(ATI) of H2 molecules. We have considered excitation from the ground state X-singlet-Sigma-g+(v=0,j) to

Concurrence vs. purity: Influence of local channels on Bell states of two qubits
, 2005 We analyze how a maximally entangled state of two-qubits (e.g., the singlet $\psi_s$) is affected by action of local channels described by completely positive maps $\cE$ .
