Isotope effect in superconducting n-doped SrTiO3
We report the influence on the superconducting critical temperature Tc in doped SrTiO3 of the substitution of the natural 16O atoms by the heavier isotope 18O. We observe that for a wide range of doping this substitution causes a strong (~50%) enhancement of Tc. Also the magnetic critical field Hc2 is increased by a factor ~2. Such a strong impact on Tc and Hc2, with a sign opposite to conventi...
متن کاملInverse Deuterium Isotope Effect in the Intersystem Crossing of Diphenylcarbene
They are important chemical intermediates whose spin state dependent chemistry is implicated in a large number of organic reactions [l-4]. An important feature relevant to an understanding of many of their physical and chemical properties is the small energy gap separating the lowest singlet and triplet states. In fact for a number of carbenes these two states are in equilibrium at room tempera...
متن کاملA note on Inverse Iteration
Inverse iteration, if applied to a symmetric positive definite matrix, is shown to generate a sequence of iterates with monotonously decreasing Rayleigh quotients. We present sharp bounds from above and from below which highlight inverse iteration as a descent scheme for the Rayleigh quotient. Such estimates provide the background for the analysis of the behavior of the Rayleigh quotient in cer...
متن کاملIsotope effect on the superconducting critical temperature of cuprates in the presence of charge order
Using the large-N limit of the t–J model and also allowing for phonons and the electron–phonon interaction, we study the isotope effect α for coupling constants appropriate for YB2C3Oy. We find that α has a minimum at optimal doping and increases strongly (slightly) towards the underdoped (overdoped) region. Using values for the electron–phonon interaction from the local density approximation w...
متن کاملA note on infinitely distributive inverse semigroups
By an infinitely distributive inverse semigroup will be meant an inverse semigroup S such that for every subset X ⊆ S and every s ∈ S, if ∨ X exists then so does ∨ (sX), and furthermore ∨ (sX) = s ∨ X. One important aspect is that the infinite distributivity of E(S) implies that of S; that is, if the multiplication of E(S) distributes over all the joins that exist in E(S) then S is infinitely d...
