We have performed a vacuum ultraviolet laser excited photoemission spectroscopy on a d-electron heavy-fermion-like material LiV2O4 single crystal. We observed a sharp peak structure in the density of states at approximately 4 meV above the Fermi level (E(F)). The evolution of the peak height corresponds well with the crossover behavior to the heavy-fermion-like state as observed in the thermal ...
A non group theoretic proof of completeness of arbitrary coherent states D(α) | f > Abstract A new proof for the completeness of the coherent states D(α) | f > for the Heisenberg Weyl group and the groups SU (2) and SU (1, 1) is presented. Generalizations of these results and their consequences are disussed.
A synthetic route to a trifluoromethyl and thiol containing glucose derivative (2,2,2-trifluoroethyl 6-thio-β-D-glucopyranoside) is presented, which is based on microwave-assisted Fischer glycosylation under increased pressure. This water-soluble, neutral thiol-compound can be used to selectively introduce a fluorine probe for (19)F NMR spectroscopy on cysteines in proteins. It can be attached ...

Scanning micro-Raman spectroscopy has been utilized to image and investigate strain in He-implanted congruent LiNbO3 samples. By using abruptly patterned implanted samples, we show that the spatial twodimensional mapping of the Raman spectral peaks can be used to image the strain distribution and determine its absolute magnitude. We demonstrate that both shortand long-range length-scale in-plan...
فرض کنیم $a:[0,infty] ightarrow l(mathbb{c}^n,mathbb{c}^n)$ نگاشت اندازه پذیر لبگی باشد که در شرط $$sup_{sgeq0}int_0^infty |e^{int_s^t [a( au)-2m(a( au)i_n]d au}|dt<infty.$$ صدق کند. نگاشت فنرگون $-a(t)$ مجانبی را در فضای اقلیدسی $mathbb{c}^n$ تعریف می کنیم و به بررسی ارتباط بین این مفهوم و زنجیرهای لاونر می پردازیم. همچنین با تعریف مفهوم نمایش $-a(t)$ پارامتری، نشان می دهیم هرگاه...
