In most materials, particles such as electrons move freely. Some quantum phases of matter, however, host fractons.

What they work on
- Construct microscopic models and hybrid fracton field theories to describe the collective behavior of fractons, particle-like excitations with restricted mobility, and the phases and phase transitions they form.
- Test whether fracton and topological states keep quantum coherence and entanglement in open quantum systems exposed to environmental noise.
- Explore whether decoherence can produce new mixed-state phases that cannot exist in thermal equilibrium, and characterize dissipation in dynamical phase transitions.
- Design algorithms to control fracton phases in dynamic, out-of-equilibrium settings, aimed at quantum error correction and information processing.
More about the research
These are particle-like excitations that cannot move on their own and often have to bind together in groups before they can move. This restricted motion is reshaping ideas about matter across quantum materials, quantum field theory and quantum information science. It could also help protect stored quantum information, which makes fractons interesting for building quantum computers.
Why it matters
Understanding whether fracton and topological states survive noise could inform quantum error correction, scalable quantum simulators and more robust quantum information processing. The work also connects condensed matter physics with quantum information theory.
Known grants
