Quantum-Geometric Raman Response in Multiorbital Flat-Band Systems
Wai Ting Tai, Martin Claassen
The paper develops a perturbative theory showing that the quantum geometric tensor generates a finite Raman scattering vertex in multiorbital flat‑band systems, enabling polarizati…
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…
Linear and Non-Linear Response of Quadratic Lindbladians
Spenser Talkington, Martin Claassen
Quadratic Lindbladians encompass a rich class of dissipative electronic and bosonic quantum systems, which have been predicted to host new and exotic physics. In this study, we dev…
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…
