Ultrastrong Magnon-Magnon Coupling Dominated by Antiresonant Interactions
Takuma Makihara, Kenji Hayashida, G. Timothy Noe +13
Exotic quantum vacuum phenomena are predicted in cavity quantum electrodynamics (QED) systems with ultrastrong light-matter interactions. Their ground states are predicted to be va…
Magnonic Superradiant Phase Transition
Motoaki Bamba, Xinwei Li, Nicolas Marquez Peraca +1
We show that the low-temperature phase transition in ErFeO3 that occurs at a critical temperature of ~ 4 K can be described as a magnonic version of the superradiant phase transiti…
Observation of Photoinduced Terahertz Gain in GaAs Quantum Wells: Evidence for Radiative Two-Exciton-to-Biexciton Scattering
X. Li, K. Yoshioka, Q. Zhang +9
We have observed photoinduced negative optical conductivity, or gain, in the terahertz frequency range in a GaAs multiple-quantum-well structure in a strong perpendicular magnetic…
