Stability of nodal quasi-particles in superconductors with coexisting orders
E. Berg, C-C. Chen, S. A. Kivelson
We establish a condition for the perturbative stability of zero energy nodal points in the quasi-particle spectrum of superconductors in the presence of coexisting \textit{commensu…
Superconductivity in zigzag CuO chains
Erez Berg, Theodore H. Geballe, Steven A. Kivelson
Superconductivity has recently been discovered in PrBaCuO with a maximum of about 15K. Since the CuO planes in this material are believed to be ins…
Theory of the nodal nematic quantum phase transition in superconductors
Eun-Ah Kim, Michael J. Lawler, Paul Oreto +3
We study the character of an Ising nematic quantum phase transition (QPT) deep inside a d-wave superconducting state with nodal quasiparticles in a two-dimensional tetragonal cryst…
Dynamical layer decoupling in a stripe-ordered, high T_c superconductor
Erez Berg, Eduardo Fradkin, Eun-Ah Kim +4
In the stripe-ordered state of a strongly-correlated two-dimensional electronic system, under a set of special circumstances, the superconducting condensate, like the magnetic orde…
