To model this effect, we consider the angle dependence of the effective Fermi velocity along the underlying Fermi surface. Pressure-induced phase transitions and superconductivity in a black phosphorus single crystal. As a particle approaches the barrier, it is described by a free particle wavefunction. We propose a possible scenario that this universal behavior can be naturally explained by invoking a strong momentum dependence of renormalization due to the nodal gap structure. The low-temperature data for BaFe 2 As 0. For reproduction of material from PPS:
This can be modeled by introducing a minimum value for. B 6 , — Published 1 October Using a tunnel diode oscillator with a novel coil geometry designed to avoid spurious contributions to , we have established the existence of intrinsic and anomalous power law behaviour at low temperature. Figure 1 Penetration depth shift as a function of temperature in LaNiC 2 single crystals at ambient pressure. Its publishing company, IOP Publishing, is a world leader in professional scientific communications. QUANTUM MATTER is a peer-reviewed interdisciplinary journal consolidating research activities in all theoretical, experimental and technological aspects dealing with fundamental structure of matter from cosmology to materials science.

With pressure the superconducting transition seems to become sharper and the critical temperature slightly increases. The wavelength of incoming light and photon absorption depth are directly related; the shorter the wavelength, the shorter the penetration depth into the silicon.
