Introduction to Unconventional Superconductivity
This lecture gives a basic introduction into some aspects of the unconventional superconductivity. First we analyze the conditions to realize unconventional superconductivity in strongly correlated electron systems. Then an introduction of the generalized BCS theory is given and several key properties of unconventional pairing states are discussed. The phenomenological treatment based on the Gi...
متن کاملThe challenge of unconventional superconductivity.
During the past few decades, several new classes of superconductors have been discovered that do not appear to be related to traditional superconductors. The source of the superconductivity of these materials is likely different from the electron-ion interactions that are at the heart of conventional superconductivity. Developing a rigorous theory for any of these classes of materials has prove...
متن کاملUnconventional superconductivity in Sr 2 RuO 4
We have performed ZF-lSR measurements of Sr 2 RuO 4 and have observed a spontaneous magnetic "eld below 1 # . This observation, combined with other symmetry considerations demonstrates that superconductivity in Sr 2 RuO 4 is of &p-wave' (odd-parity) type. Our transverse "eld lSR measurements in the mixed state with B"150 GDDc( clearly indicate the presence of a square #ux lattice. We have analy...
متن کاملUnconventional superconductivity and magnetism in CePt3Si1−xGex
CePt3Si is a novel ternary compound exhibiting antiferromagnetic order at TN ≈ 2.2 K and superconductivity (SC) at Tc ≈ 0.75 K. Large values of H ′ c2 ≈ −8.5 T/K and Hc2(0) ≈ 5 T indicate Cooper pairs formed out of heavy quasiparticles. The mass enhancement originates from Kondo interaction with a characteristic temperature TK ≈ 8 K. NMR and μSRmeasurements evidence coexistence of SC and long r...
متن کاملUnconventional superconductivity on a topological insulator.
We study proximity-induced superconductivity on the surface of a topological insulator (TI), focusing on unconventional pairing. We find that the excitation spectrum becomes gapless for any spin-triplet pairing, such that both subgap bound states and Andreev reflection is strongly suppressed. For spin-singlet pairing, the zero-energy surface state in the d(xy)-wave case becomes a Majorana fermi...
