Interaction effects in quantum interferometers
… integer quantum Hall regime. The behaviour of electrons in condensed matter systems is mostly determined by the repulsive Coulomb interaction. However, under special circumstances the Coulomb interaction can be effectively attractive, giving rise to electron-pairing in unconventional …

Growth and characterisation of Niobium/Gadolinium superconductor-ferromagnet nanocomposites
… is the phonon-mediated attraction energy between electrons which results in the formation of the so-called Cooper pairs, is usually smaller that the exchange (Zeeman) interaction between electrons which tend to align the electron spins. However, non-zero total momentum Cooper pairs can be …

Evolution of the excitation spectrum of cuprate superconductors with doping and temperature
… question in this field is how the strength of electron pairing evolves as a function of doping and temperature and whether pairing strength and the Tc of the sample are related, as they are in simple BCS superconductors. To address these questions, we have developed several new experimental …

Mass spectrometry of substituted benzils
… that all parent-molecule ions are formed by electron capture, and all fragments by dissociative-attachment. The electron-withdrawing substituents cause a broadening of the ionization efficiency curve for the parent-molecule ion; all other substituents have no effect on the curves' shape. …

Investigation of renormalization effects in high temperature cuprate superconductors
… in conventional superconductors coupling between electrons and phonons is known to be responsible for the electron pairing, for the high temperature superconductors the pairing media remains under debates. Since the interactions of electrons with other degrees of freedom (phonons, magnetic …

Transport studies of reentrant integer quantum Hall states forming in the two-dimensional electron gas
<p>The two dimensional electron gas subjected to a magnetic field has been a model system in contemporary condensed matter physics which generated many beautiful experiments as well as novel fundamental concepts. These novel concepts are of broad interests and have benefited other fields of …
