Quantum Phase Transitions with Spin Frustration in a Trapped Ion System

POSTER

Abstract

We discuss the use of a linear array of trapped ions for quantum simulations of spin chains with long range interactions [1,2]. In particular, we study interesting phase diagrams with only a few ions that involve multiple normal modes of motion and can feature spin frustration. With trapped ions, there is a potential to directly study the entanglement structure in such exotic ground state spin phases. \newline \newline This work is supported by the DARPA OLE Program under ARO contract, IARPA under ARO contract, ~the NSF PIF Program, and the NSF Physics Frontier Center at JQI. \newline \newline [1] D.
