Quantum-Geometric Raman Response in Multiorbital Flat-Band Systems
Wai Ting Tai, Martin Claassen
Flat-band materials host rich collective phenomena, yet a complete theory of their signatures in inelastic light scattering remains lacking. While naive theories of interacting fla…
Polarization-Resolved Photon Statistics of Cavity Quantum Materials
Benjamin Kass, Spenser Talkington, Martin Claassen
By forming hybrid light-matter states, optical cavities offer a route for engineering material properties, however, unambiguously probing the effects of light-matter coupling remai…
Extrinsic quantum geometry in the quadrupolar bulk photovoltaic effect
Steven Gassner, Swati Chaudhary, Martin Claassen
The bulk photovoltaic effect has become a valuable probe of the quantum geometry of Bloch bands. While it is restricted to inversion-broken systems within the dipole approximation,…
Ultrastrong Coupling Signatures in Photon Statistics from Terahertz Higgs-Polaritons
Spenser Talkington, Benjamin Kass, Martin Claassen
The ultrastrong coupling regime of cavity photons and quantum materials has emerged as a pathway to modify materials properties, however definitive signatures of ultrastrong coupli…
Many-Body Photon Blockade and Quantum Light Generation from Cavity Quantum Materials
Benjamin Kass, Spenser Talkington, Ajit Srivastava +1
The strong coupling regime of photons and quantum materials inside optical cavities has emerged as a promising environment for manipulating states of matter with light. Here, in tu…
