For decades, the classical order parameters framework of Landau-Wilson has dominated the discussion of condensed matter systems, with extensions to incorporate topological states of weakly interacting electrons. In this talk, I will focus instead on new physics that arises from strong interactions and its interplay with topology. A unifying theme will be the emergence of gauge fields, which will be illustrated with two recent works. The first describes a route to realizing a long sought after phase - the Z2 quantum spin liquid - in an array of highly excited (Rydberg) atoms. Experimental progress towards this goal will also be briefly mentioned. Next, I will discuss new strategies to create quantum states including deconfined phases of non-Abelian gauge theories. Measurements play a key role in this proposal. Prospects for realizing these states in existing term quantum platforms will also be discussed.
