The invention is directed to a color-tunable emitter material comprising a crystal containing complexes of luminescent biomolecule-based ligands and metal ions and to a method for preparing the color-tunable emitter material. Furthermore, the invention rel ...
Using a specially designed Monte Carlo algorithm with directed loops, we investigate the triangular lattice Ising antiferromagnet with coupling beyond the nearest neighbors. We show that the first-order transition from the stripe state to the paramagnet ca ...
Two-dimensional Fourier-transform techniques were used to observe the deuteron double quantum transition for DC.tbd.CCN and CDCl3 partially oriented in a nematic solvent. Obsd. linewidths agree well with those calcd. from appropriate spin-lattice relaxatio ...

Electronic nematic materials are characterized by a lowered symmetry of the electronic system compared to the underlying lattice, in analogy to the directional alignment without translational order in nematic liquid crystals1. Such nematic phases appear in ...
The phase diagram of the classical J1–J2 model on the kagome lattice is investigated by using extensive Monte Carlo simulations. In a realistic range of parameters, this model has a low-temperature chiral-ordered phase without long-range spin order. We sho ...
