The coherent-state transformation in quantum electrodynamics coupled cluster theory
Eric W. Fischer
We analyse the coherent-state (CS) transformation in quantum electrodynamics coupled cluster (QED-CC) theory from the perspective of its non-vanishing commutator with the polariton…
Cavity-Modified Zeeman Effect via Spin-Polariton Formation
Eric W. Fischer, Michael Roemelt
We study the electronic spin Zeeman effect for an effective spin--system subject to both strong coupling to a low-frequency optical cavity and an external static magnetic fiel…
Cavity Born-Oppenheimer Coupled Cluster Theory: Towards Electron Correlation in the Vibrational Strong Light-Matter Coupling Regime
Eric W. Fischer
We present a detailed derivation and discussion of cavity Born-Oppenheimer coupled cluster (CBO-CC) theory and address cavity-modified electron correlation in the vibrational stron…
High-harmonic generation under electronic strong coupling: A time-dependent combined quantum electrodynamics/quantum chemistry study
Paul A. Albrecht, Eric W. Fischer, Tillmann Klamroth +1
The creation of light-matter hybrid states, polaritons, in a cavity offers new intriguing opportunities to manipulate the electronic structure and electron dynamics of atoms and mo…
