Multimode equilibrium approximations in light-matter systems from weak to strong coupling
Davis M. Welakuh, Vasil Rokaj, Michael Ruggenthaler +1
In this work, we detail different approaches to treat multi-mode photonic environments within non-relativistic quantum electrodynamics in the long-wavelength approximation efficien…
Non-perturbative Mass Renormalization Effects in Non-relativistic Quantum Electrodynamics
Davis M. Welakuh, Vasil Rokaj, Michael Ruggenthaler +1
In this work we investigate the effects that multi-mode photonic environments, e.g., optical cavities, have on the properties of quantum matter. We highlight the importance of the…
Cavity-Mediated Molecular Entanglement and Generation of Non-Classical States of Light
Davis M. Welakuh, Spyros Tserkis, Scott E. Smart +1
The generation and control of entanglement in a quantum mechanical system is a critical element of nearly all quantum applications. Molecular systems are a promising candidate, wit…
Many-Body Excited States with a Contracted Quantum Eigensolver
Scott E. Smart, Davis M. Welakuh, Prineha Narang
Calculating ground and excited states is an exciting prospect for near-term quantum computing applications, and accurate and efficient algorithms are needed to assess viable direct…
Down-conversion processes in ab-initio non-relativistic quantum electrodynamics
Davis M. Welakuh, Michael Ruggenthaler, Mary-Leena M. Tchenkoue +2
The availability of efficient photon sources with specific properties is important for quantum-technological applications. However, the realization of such photon sources is often…
Light-matter interaction in the long-wavelength limit: no ground-state without dipole self-energy
Vasil Rokaj, Davis M. Welakuh, Michael Ruggenthaler +1
Most theoretical studies for correlated light-matter systems are performed within the long-wavelength limit, i.e., the electromagnetic field is assumed to be spatially uniform. In…
