Intertwined orders and fermions in holography
Sera Cremonini (Lehigh)
Behind the unconventional behavior of many strongly interacting quantum systems is an intrinsically complex phase diagram exhibiting a variety of orders. These may not only compete but also cooperate with each other, describing phases with a common origin that are intertwined. Holographic techniques provide a theoretical laboratory to probe such strongly correlated systems, offering a new window into their dynamics.
In this talk I will discuss a holographic model of a striped superconductor, which provides a concrete realization of intertwined orders. I will also examine the formation and structure of Fermi surfaces in various holographic systems with broken translational invariance. In particular, we will see that sufficiently strong lattice effects generically cause the Fermi surface to dissolve, leaving behind disconnected segments. This segmentation process is reminiscent of the puzzling Fermi arc phenomenon observed in the high temperature superconductors.
