Magnetically Tuned Continuous Transition from Weak to Strong Coupling in Terahertz Magnon Polaritons
Andrey Baydin, Kenji Hayashida, Takuma Makihara +11
Depending on the relative rates of coupling and dissipation, a light-matter coupled system is either in the weak- or strong-coupling regime. Here, we present a unique system where…
Tunable Plasmonic Ultrastrong Coupling: Emulating Dicke Physics at Room Temperature
Riad Yahiaoui, Zizwe A. Chase, Chan Kyaw +8
A system of N two-level atoms cooperatively interacting with a photonic field can be described as a single giant atom coupled to the field with interaction strength ~N^0.5. This en…
Magnetic Control of Soft Chiral Phonons in PbTe
Andrey Baydin, Felix G. G. Hernandez, Martin Rodriguez-Vega +10
PbTe crystals have a soft transverse optical phonon mode in the terahertz frequency range, which is known to efficiently decay into heat-carrying acoustic phonons, resulting in ano…
