Title: Terahertz Cavity Quantum Electrodynamics
Abstract:
Nonperturbative coupling of light with condensed matter in an optical
cavity is expected to reveal a host of coherent many-body phenomena and
states. In addition, strong coherent light-matter interaction in a solid-state
environment is of great interest to emerging quantum-based technologies.
However, creating a system that combines a long electronic coherence time,
a large dipole moment, and a high cavity quality (Q) factor has been a
challenging goal. After reviewing previous studies on cavity quantum electrodynamics
in solids, this talk will describe our recent observation of collective
ultrastrong light-matter coupling in an ultrahigh-mobility two-dimensional
electron gas (2DEG) in a high-Q terahertz photonic-crystal cavity in a
quantizing magnetic field, demonstrating a cooperativity of 360 [1].
