Hardware-efficient formulation of molecular cavity-QED Hamiltonians
Francesco Troisi, Simone Latini, Heiko Appel +3
Light-matter coupled Hamiltonians are central to cavity materials engineering and polaritonic chemistry, but are challenging to simulate with classical hardware due to the scaling…
Strong long-wavelength electron-phonon coupling in TaNi(Se,S)
Zhibo Kang, Burak Gurlek, Weichen Tang +9
The search for intrinsic excitonic insulators (EI) has long been confounded by coexisting electron-phonon coupling in bulk materials. Although the ground state of an EI may be diff…
Cavity-QED-controlled two-dimensional Moiré Excitons without twisting
Francesco Troisi, Hannes Hübener, Angel Rubio +1
We propose an all-optical Moiré-like exciton confinement by means of spatially periodic optical cavities. Such periodic photonic structures can control the material properties by…
Modifying electronic and structural properties of 2D van der Waals materials via cavity quantum vacuum fluctuations: A first-principles QEDFT study
Hang Liu, Simone Latini, I-Te Lu +2
Structuring the photon density of states and light-matter coupling in optical cavities has emerged as a promising approach to modifying the equilibrium properties of materials thro…
Multiple Photon Field-induced Topological States in Bulk HgTe
Dongbin Shin, I-Te Lu, Benshu Fan +6
Strong light-matter interactions can be exploited to modify properties of quantum materials both in and out of thermal equilibrium. Recent studies suggest electromagnetic fields in…
Cavity-Mediated Electron-Electron Interactions: Renormalizing Dirac States in Graphene
Hang Liu, Francesco Troisi, Hannes Hübener +2
Embedding materials in optical cavities has emerged as a strategy for tuning material properties. Accurate simulations of electrons in materials interacting with quantum photon flu…
