Phase diagram of electron systems near the superconductor-insulator transition.
The zero temperature phase diagram of Cooper pairs exposed to disorder and a magnetic field is determined theoretically from a variational approach. Four distinct phases are found: a Bose and a Fermi insulating, a metallic, and a superconducting phase, respectively. The results explain the giant negative magnetoresistance found experimentally in In-O, TiN, Be and high-T(c) materials.
متن کاملCompensation-driven superconductor-insulator transition
The superconductor-insulator transition in the presence of strong compensation of dopants was recently realized in La doped yttrium barium copper oxide. The compensation of acceptors by donors makes it possible to change independently the concentration of holes n and the total concentration of charged impurities N. We propose a theory of the superconductor-insulator phase diagram in the N ,n pl...
متن کاملThe Superconductor Insulator Transition
As the thickness or magnetic field is varied in thin films a transition between superconducting and insulating phases takes place. This quantum phase transition obeys scaling relations and occurs at seemingly universal critical resistance. This paper reviews experiments that demonstrate this transition and measure the critical exponents. The microscopic theories are outlined and lead to differe...
متن کاملDriving a Superconductor to Insulator Transition with Random Gauge Fields
Typically the disorder that alters the interference of particle waves to produce Anderson localization is potential scattering from randomly placed impurities. Here we show that disorder in the form of random gauge fields that act directly on particle phases can also drive localization. We present evidence of a superfluid bose glass to insulator transition at a critical level of this gauge fiel...
متن کاملMagnetic-Field-Driven Superconductor-Insulator-Type Transition in Graphite
A magnetic-field-driven transition from metallicto semiconducting-type behavior in the basal-plane resistance takes place in highly oriented pyrolytic graphite at a field Hc ∼ 1 kOe applied along the hexagonal c-axis. The analysis of the data reveals a striking similarity between this transition and that measured in thinfilm superconductors and Si MOSFET’s. However, in contrast to those materia...
