AC-Stark Spectroscopy of Interactions between Moiré Excitons and Polarons
B. Evrard, H. S. Adlong, A. A. Ghita +6
We use nonlinear pump-probe spectroscopy to study optical excitations in a charge-tunable MoSe\WS moiré heterostructure. An intense red-detuned laser pulse creates a photon…
Parametric instability in a magnomechanical system
Takahiro Uto, Daigo Oue
We study parametric instability in a magnomechanical system, specifically examining magnon tunneling between moving ferromagnetic insulators. Our analysis reveals that quantum fluc…
Interaction induced AC-Stark shift of exciton-polaron resonances
Takahiro Uto, Bertrand Evrard, Kenji Watanabe +3
Laser induced shift of atomic states due to the AC-Stark effect has played a central role in cold-atom physics and facilitated their emergence as analog quantum simulators. Here, w…
Helical dichroism for hybridized quadrupole plasmon modes in twisted nanorods
Takahiro Uto, An'an Wu, Tsutomu Shimura +1
Helical dichroism (HD), originating from the interplay between chiral plasmonic structures and left and right vortex light carrying orbital angular momentum (OAM), has attracted si…
