Advanced Quantum Materials - A New Frontier for Ultracold Atoms
Abstract
The central goal of this project has been to study theoretically and realize experimentally new quantum phases of matter that go beyond this simple paradigm of symmetry breaking, order parameters, and mean-field description. The key ingredients necessary for these states are topology, frustration, and a high degree of degeneracy. Recent experimental progress with ultracold atoms gives us the tools necessary for realizing such novel states of matter. Band structures can be designed to offer nontrivial topology and to contain numerous degeneracies, thereby amplifying interactions. Frustration in spin systems can be enhanced by selecting the lattice geometry, going to higher SU(N) symmetry, or by having longer range interactions. Systems that we have realized can be broadly divided into two broad categories. The first one will be systems that are completely new and do not have counterparts in Nature, and the second one will be realizations of idealized states that provide paradigms for our understanding of fundamental nontrivial states of matter.
