Dr. Rukmani Bai,  a postdoctoral fellow at Leibniz University Hannover, Germany gave a talk on Quantum simulation with Ultracold and Rydberg atoms in optical lattices on  19  January.

Here is the summary of the talk:  Quantum simulation with optical lattices provides a powerful platform for quantum computation. It enables the engineering and study of strongly correlated quantum phases that can serve as building blocks for fault-tolerant quantum devices. Ultracold atoms in engineered lattice geometries allow precise control over interactions, hopping, and synthetic gauge fields. This control makes it possible to realize topological phases, such as fractional quantum Hall states, and other exotic many-body phases that are difficult to observe in solids because they require strong magnetic fields (~100 T) and strong electron interactions. Ultracold atomic systems offer a clean and highly tunable alternative, with synthetic fields exceeding ~1000 T achievable via lasers. Rydberg atom arrays are particularly promising. They provide tunable long-range interactions, adjustable lattice geometries, and intrinsic spin-orbit coupling. Such platforms not only open pathways toward robust quantum computation but also serve as versatile playgrounds for exploring fundamental many-body physics. In this talk, I will discuss various artificial platforms based on Ultracold and Rydberg atoms for realizing topological phases and strongly correlated quantum states, highlighting their relevance for quantum simulation and quantum computation.

Dr. Rukmani Bai obtained her Ph.D from Physical Research Laboratory Ahmedabad in 2018 under the supervision of Prof. Dilip Angom.  Then she moved to the University of Stuttgart, Germany to do a postdoc with Prof. Hans Peter Buechler from 2019-2024.  Currently, she is a postdoctoral fellow at Leibniz University Hannover, Germany working with Prof. Luis Santos from September 2024.  Her current research interests are study of quantum and topological phases of matter using ultracold atoms, Rydberg atom physics, physics of ultracold atoms trapped in the optical lattices, study of dipolar ultracold atomic mixtures.
