Bridging Platforms: Exploration and Control of Fractionalized States

Coordinators: Immanuel Bloch, Titus Neupert, Pedram Roushan, and Ady Stern

Fractionalization is now being explored in a wide variety of platforms—from layered materials to programmable quantum devices. This conference explores how fractionalized states emerge from microscopic physics, what techniques can reliably detect and manipulate them, and how insights from different experimental platforms can inform one another. Topics will include fractionalization arising from geometric frustration in magnetic and other systems, detection and control of anyons across diverse platforms including fractional quantum Hall states, fractional Chern insulators and quantum simulators, and novel phenomena in systems beyond conventional gapped phases, such as fractons and gapless fractionalized states.

This conference will hold a poster session all posters are welcome. Each poster board is 4 feet high x 6 feet wide. We ask that the posters be no larger than 44 inches high x 34 inches wide at the most (it is important to follow these measurements or posters may be turned down due to limited space).
