Once Upon a Time in Kamchatka - The Extraordinary Search for Natural Quasicrystals

Paul J. Steinhardt (Princeton University, New Jersey, USA)

Abstract: Quasicrystals are exotic materials with symmetries that were once thought to be impossible for matter. The first known examples were synthesized in the laboratory over 35 years ago, but could Nature have beaten us to the punch? This talk will describe the search that took over a dozen years to answer this question, resulting in one of the strangest scientific stories you are ever likely to hear.

Synthetic dimensions in ultracold polar molecules: from topology to quantum strings

Bhuvanesh Sundar (Rice University (Houston, USA))

Synthetic dimensions alter one of the most fundamental properties in nature, the dimension of space. We show that rotational states of ultracold molecules can be used as synthetic dimensions extending to many - potentially hundreds of - synthetic lattice sites. Microwaves coupling rotational states 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 interaction strength, resulting in a quantum string or a membrane, with an emergent condensate that lives on this string or membrane. We explore the properties of these phases using mean field, exact, and density-matrix-renormalization-group solutions. We show that when molecules are frozen in a real space lattice with staggered synthetic tunnelings, the edge states in the synthetic direction are stabilized against scattering into the bulk by the introduction of dissipation in the system. All the physics above can be detected using measurements of rotational state populations.
