A semi-empirical calculation of the 6s-7s Stark amplitude α in Cs has been performed using the most accurate measurements and calculations of the electromagnetic amplitudes available. This is then used to extract the parameters of the electroweak theory from experimental data. The results are: α = 269.0(1.3)a 3 0 , weak charge of Cs Q W = −72.41(25) exp… (More)

A quantitative study of the field-induced magnetic ordering in TlCuCl3 in terms of a Bose-Einstein condensation (BEC) of magnons is presented. It is shown that the hitherto proposed simple BEC scenario is in quantitative and qualitative disagreement with experiment. It is further shown that even very small Dzyaloshinsky-Moriya interactions or a staggered g… (More)

We study the behaviour of the electronic chemical potential in YBa 2 Cu 3 O 6+δ near the superconducting transition using the spin-wave exchange theory of pairing. We find that the experimental value of the jump in the temperature derivative of the chemical potential is inconsistent with the theoretical value calculated under the assumption of constant hole… (More)

We find unknown s- and d-wave amplitudes of the recently discovered charge density wave (CDW) in underdoped cuprates. To do so we perform a combined analysis of experimental data for ortho-II YBa2Cu3Oy. The analysis includes data on nuclear magnetic resonance, resonant inelastic X-ray scattering, and hard X-ray diffraction. The amplitude of doping… (More)

For two interacting particles (TIP) in one-dimensional random potential the dependence of the Breit-Wigner width Γ, the local density of states and the TIP localiza-tion length on system parameters is determined analytically. The theoretical predictions for Γ are confirmed by numerical simulations.
