Quantum Photonic Integrated Design Center (QuPIDC):
QuPIDC
is a Department of Energy (DOE) Energy Frontier Research Center (EFRC) led by Purdue University and directed by Professor Libai Huang. Its mission is to discover, design, and realize robust many-body entangled photon and matter states using multi-scale co-design strategies in heterogeneous solid-state photonic systems.
Quantum Transport of Excitons and Charges Imaged by Ultrafast Microscopy:
The transport of energy carriers, such as electrons and excitons, in solid-state materials is fundamentally determined by their wavefunctions and interactions with the lattice and surrounding environment. The wave-like properties of these particles play a critical role in their transport behavior. However, probing transport in the quantum regime poses significant challenges due to rapid dephasing (on the picosecond or shorter timescale) and nanoscale localization. To overcome these challenges, Huang's group has developed experimental approaches that combine optical microscopy and ultrafast femtosecond spectroscopy. These tools enable imaging of quantum exciton transport across time and length scales and over a broad range of temperatures, in two-dimensional materials, molecular aggregates and quantum dot superlattices.
Exciton Many-Body Interactions:
Excitons provide a promising platform for exploring quantum many-body physics, serving as a solid-state analog to ultracold gases confined in optical lattices for quantum simulations. Huang's group investigates critical open questions surrounding the coherence and dynamics of quantum phases formed by photoexcited excitons, particularly in the presence of dissipation and relaxation. This research aims to unravel the fundamental mechanisms governing these quantum phases and their behavior in complex systems.
