Casimir energy and the superconducting phase transition
We study the influence of Casimir energy on the critical field of a superconducting film, and we show that by this means it might be possible to directly measure, for the first time, the variation of Casimir energy that accompanies the superconducting transition. It is shown that this novel approach may also help clarifying the long-standing controversy on the contribution of TE zero modes to t...
متن کاملA mathematical proof that the transition to a superconducting state is a second-order phase transition
We deal with the gap function and the thermodynamical potential in the BCSBogoliubov theory of superconductivity, where the gap function is a function of the temperature T only. We show that the squared gap function is of class C on the closed interval [ 0, Tc ] and point out some more properties of the gap function. Here, Tc stands for the transition temperature. On the basis of this study we ...
متن کاملSuperconducting Transition in Electron-Doped 12CaO 7Al2O3
It was reported that a mixed light metal oxide compound, 12CaO 7Al2O3 (C12A7), which is known as a constituent of aluminous cement, became a superconductor at an ambient pressure by the exclusive replacement of extra-framework oxygen ions in subnanometer-sized crystallographic cages with electrons. Temperature dependences of resistivity, magnetic susceptibility, and magnetic field dependent res...
متن کاملSuperconducting transition temperatures of the elements related to elastic constants
For a given crystal structure, say body-centred-cubic, the many-body Hamiltonian H in which nuclear and electron motions are to be treated from the outset on the same footing, has parameters, for the elements, which can be classified as (i) atomic mass M , (ii) atomic number Z, characterizing the external potential in which electrons move, and (iii) bcc lattice spacing, or equivalently one can ...
متن کاملScaling and Duality in the Superconducting Phase Transition
The renewed interest for critical fluctuations in superconductors is due to the enormous variety of interesting phenomena observed in the last decade. In a zero external field regime, non-classical values of the critical exponents and amplitude ratios were measured. In the observed critical region we have −0.03 < α < 0, ν ≈ 0.67 and A+/A− ≈ 1.065. These values were measured for bulk samples of ...
