DESCRIPTION:Speaker: Bhuvanesh Sundar\nhosted by Misha Lemeshko\nAbstract: 
 Synthetic dimensions alter one of the most fundamental properties in natur
 e\, the dimension of space. We show that rotational states of ultracold mo
 lecules can be used as synthetic dimensions extending to many - potentiall
 y hundreds of - synthetic lattice sites. Microwaves coupling rotational st
 ates drive fully controllable synthetic inter-site tunnelings\, enabling\,
  for example\, topological band structures. We show that interactions lead
  to rich behavior. When molecules are frozen in a real space lattice with 
 uniform synthetic tunnelings\, dipole interactions cause the molecules to 
 aggregate to a narrow strip in the synthetic direction beyond a critical i
 nteraction strength\, resulting in a quantum string or a membrane\, with a
 n emergent condensate that lives on this string or membrane. We explore th
 e properties of these phases using mean field\, exact\, and density-matrix
 -renormalization-group solutions. We show that when molecules are frozen i
 n a real space lattice with staggered synthetic tunnelings\, the edge stat
 es in the synthetic direction are stabilized against scattering into the b
 ulk by the introduction of dissipation in the system. All the physics abov
 e can be detected using measurements of rotational state populations.
