Kondo tunneling through real and artificial molecules
, 2000 When a cerocene molecule is chemisorbed on metallic substrate, or when an asymmetric double dot is hybridized with itinerant electrons, its singlet ground state crosses its lowly excited triplet state, leading to a competition between the Zhang-Rice ...

Singlet excited-state absorption of eosin Y [PDF]
Chemical Physics, 1993 Abstract The absolute S1-state absorption cross-section spectrum of eosin Y in methanol has been determined by pico-second second harmonic Nd:glass laser excitation and time-delayed picosecond light continuum probing (probing wavelength region from 400 to 980 nm).

Investigation of the spin-forbidden process in thymine [PDF]
Hemijska Industrija, 2012 The intersystem crossing rate from the lowest singlet to the lowest triplet state of thymine was studied by means of the ab initio methods. The rate was calculated employing the time-dependent approach based on the correlation function.

Pyrochlore Antiferromagnet: A Three-Dimensional Quantum Spin Liquid
, 1998 The quantum pyrochlore antiferromagnet is studied by perturbative expansions and exact diagonalization of small clusters. We find that the ground state is a spin-liquid state: The spin-spin correlation functions decay exponentially with distance and the ...

Fragile singlet ground state magnetism in pyrochlore osmates R2Os2O7 (R=Y and Ho) [PDF]
, 2016 The singlet ground state magnetism in pyrochlore osmates Y$_2$Os$_2$O$_7$ and Ho$_2$Os$_2$O$_7$ is studied by DC and AC susceptibility, specific heat, and neutron powder diffraction measurements.

, 2016 We propose a robust and highly efficient NMR technique to create singlet spin order from longitudinal spin magnetization in coupled spin-1/2 pairs and to perform backward conversion (singlet order)$\to$magnetization.

Pariser-Parr-Pople Model based Investigation of Ground and Low-Lying Excited States of Long Acenes
, 2013 Several years back Angliker et al [Chem. Phys. Lett. 1982, 87, 208] predicted nonacene to be the first linear acene with the triplet state $1^{3}B_{2u}$ as the ground state, instead of the singlet $1^{1}A_{g}$ state. However, contrary to that prediction,

Manifestation of the odd-frequency spin-triplet pairing state in diffusive ferromagnet / superconductor junctions [PDF]
, 2006 Using the quasiclassical Green's function formalism, we study the influence of the odd-frequency spin-triplet superconductivity on the local density of states (LDOS) in a diffusive ferromagnet (DF) attached to a superconductor.

Chemistry with Red and Near Infrared Light
CHIMIA, 1991 Opportunities are explored to initiate controlled chemistry by photolysis with long-wavelength visible and near infrared light. In one direction, bimolecular reactions are induced by exciting collisional pairs in a solid matrix to energy ...
