Compressing Hamiltonians with ab initio downfolding for simulating strongly-correlated materials on quantum computers
Antonios M. Alvertis, Abid Khan, Norm M. Tubman
The accurate first-principles description of strongly-correlated materials is an important and challenging problem in condensed matter physics. Ab initio downfolding has emerged as…
Phonon screening of excitons in atomically thin semiconductors
Woncheol Lee, Antonios M. Alvertis, Zhenglu Li +4
Atomically thin semiconductors, encompassing both 2D materials and quantum wells, exhibit a pronounced enhancement of excitonic effects due to geometric confinement. Consequently,…
Classical Benchmarks for Variational Quantum Eigensolver Simulations of the Hubbard Model
Antonios M. Alvertis, Abid Khan, Thomas Iadecola +2
Simulating the Hubbard model is of great interest to a wide range of applications within condensed matter physics, however its solution on classical computers remains challenging i…
Rearrangement collision theory of phonon-driven exciton dissociation
Christopher J. N. Coveney, Jonah B. Haber, Antonios M. Alvertis +2
Understanding the processes governing the dissociation of excitons to free charge carriers in semiconductors and insulators is of central importance for photovoltaic applications.…
Capturing electronic correlations in electron-phonon interactions in molecular systems with the GW approximation
Antonios M. Alvertis, David B. Williams-Young, Fabien Bruneval +1
Electron-phonon interactions are of great importance to a variety of physical phenomena, and their accurate description is an important goal for first-principles calculations. Isol…
