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 کاملIntroduction to unconventional superconductivity in non-centrosymmetric metals
These lecture notes are an extension of my previous notes [1] presented in this lecture series and are concerned with the recently emerging research field of unconventional superconductivity in non-centrosymmetric metals. Inversion symmetry together with time reversal symmetry represent key symmetries for the formation of Cooper pairs in superconductors and allows to distinguish between even-pa...

To understand the mechanism of superconductivity in unconventional super onductors is one of the big challenges in the field of superconductivity. Based on the BCS theory, there is a direct relation between the pairing mechanism and the symmetry of the order parameter. Therefore, identification of the structure of the superconducting gap or the order parameter provides key information on the pa...

متن کاملFluctuating Charge Order: A Universal Phenomenon in Unconventional Superconductivity?
Unconventional superconductors are characterized by various competing ordering phenomena in the normal state, such as antiferromagnetism, charge order, orbital order or nematicity. According to a widespread view, antiferromagnetic fluctuations are the dominant ordering phenomenon in cuprates and Fe based superconductors and are responsible for electron pairing. In contrast, charge order is beli...
