Scientific Reports, 2022 The role of singlet fission (SF) in the triplet-state generation mechanism of 1,3,5,7-tetramethyl-boron-dipyrromethene derivatives is revealed by exploring the cause for the solvent dependence of the generation rate.

The inverted singlet–triplet gap: a vanishing myth?
Frontiers in Chemistry, 2023 Molecules with an inverted singlet–triplet gap (STG) between the first excited singlet and triplet states, for example, heptazine, have recently been reported and gained substantial attention since they violate the famous Hund’s rule.

Generation of a macroscopic singlet state in an atomic ensemble [PDF]
Research in Optical Sciences, 2011 We report on an experiment underway for generating a singlet state in a cold atomic ensemble. The experiment is based on a recent proposal to generate these states by applying a quantum non-demolition (QND) measurement and feedback to an unpolarized ensemble [1].

Chinese Journal of Magnetic Resonance, 2020 The long-life nuclear spin singlet states (LLSs) have broad application prospects due to the unique nature of their long lifetime. Herein, in a solution of alanylglycylgcine (AGG), the nuclear spin singlet state of a two-spin system far from the chiral ...

Quenched scalar meson correlator with Domain Wall Fermions [PDF]
, 2002 We study the singlet and non-singlet scalar-meson masses using domain wall fermions and the quenched approximation. The singlet mass is found to be smaller than the non-singlet mass and indicates that the lowest singlet meson state could be lighter than ...

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.

Modeling the singlet state with local variables [PDF]
Physics 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
