We study and solve the ground-state problem of a microscopic model for a family of orbitally degenerate quantum magnets. The orbital degrees of freedom are assumed to have a directional character and are represented by static Potts-like variables. In the l ...
Vibrational progressions due to radiative decay of A1P(v' = 0,2,3,5,6,8) e3S(v' = 3,5,12), a'3S(v' = 11,14),d3D(v' = 5) to the ground state and of e3S(v' = 3,7,9,11,12), d3D(v' = 3,7,11) to the a3P state were obsd. for selective excitation of A1P(v' = 0, . ...
Different decoupling sequences are tested - using various shaped radio-frequency (RF) pulses - to achieve the longest possible lifetimes of singlet-state populations over the widest possible bandwidths, that is, ranges of offsets and relative chemical shif ...
Femtosecond fluorescence-upconversion studies of aq. [Ru(bpy)3]2+ show a short-lived vibrationally hot emission of the singlet metal-to-ligand charge-transfer state, with an ultrafast intersystem crossing (~ 10 fs) to the triplet state at const. energy (th ...
Results of present and previous measurements of the23Na NMR response, dc- and ac-magnetic susceptibilities and the specific heat ofNa2V3O7at low temperatures suggest that this material is close to a quantum critical point (QCP) atm0H¼0 T. The experimental ...
Photoluminescence of p-type modulation doped (Cd,Mn)Te quantum wells is studied with carrier density up to 5 X 10(11) cm(-2) at various spin splittings. This splitting can be made larger than the characteristic energies of the system thanks to the giant Ze ...
The spectrally and temporally resolved fluorescence properties of native bacteriorhodopsin (bR) and bR reconstituted with a nonisomerizing analog of the retinal Schiff base (bR5.12) are examd. The first attempt to exptl. monitor the excited state relaxatio ...
The title compound 4a, a purple transient whose main UV-vis absorption band occurs near 490 nm (epsilon = 5000 M-1 cm-1), has been generated by irradiation of 2,3,5,6-tetramethylene-7-oxonorbornane (5a). It has been observed directly by immobilization in f ...
