Anisotropic spin and charge excitations in superconductors: signature of electronic nematic order
Ying-Jer Kao, Hae-Young Kee
We study spin and charge susceptibilities in the d-wave superconducting state whose underlying electronic dispersion is anisotropic due to the formation of the electronic nematic o…
Supercurrent in Nodal Superconductors
Igor Khavkine, Hae-Young Kee, Kazumi Maki
In recent years, a number of nodal superconductors have been identified; d-wave superconductors in high T_c cuprates, CeCoIn, and κ-(ET)_2Cu(NCS)_2, 2D f-wave superconductor in…
Formation of Electronic Nematic Phase in Interacting Systems
Igor Khavkine, Chung-Hou Chung, Vadim Oganesyan +1
We study the formation of an electronic nematic phase characterized by a broken point-group symmetry in interacting fermion systems within the weak coupling theory. As a function o…
An explanation for a universality of transition temperatures in families of copper oxide superconductors
Sudip Chakravarty, Hae-Young Kee, Klaus Voelker
A remarkable mystery of the copper oxide high-transition-temperature (Tc) superconductors is the dependence of Tc on the number of CuO2 layers, n, in the unit cell of a crystal. In…
