Problem-aware sampling for bias and variance reduction in randomised Hamiltonian simulation
Brian Coyle, Jonathan H. Fetherolf, Antonio Márquez Romero +3
Randomised quantum simulation algorithms such as qDRIFT reduce circuit depth by replacing deterministic product formulas with stochastic compilations, but achieving high accuracy c…
OpenQARP: a modular framework for quantum application research
Stefano Scali, Vicente P. Soloviev, Antonio Márquez Romero +7
We introduce OpenQARP, the Open Quantum Application Research Package: an open-source Python framework for quantum application research, built on a compiled C++ core. In OpenQARP, a…
Nuclear-Electronic Quantum Dynamics in a Plasmonic Nanocavity
Jonathan H. Fetherolf, Tim Duong, Tao E. Li +1
Plasmonic nanocavities are a promising platform for strong light-matter coupling and enhanced spectroscopies at the single-molecule level. These nanoscale environments are challeng…
Nuclear-electronic orbital second-order coupled cluster for excited states
Jonathan H. Fetherolf, Fabijan Pavošević, Sharon Hammes-Schiffer
Excited-state methods within the nuclear--electronic orbital (NEO) framework have the potential to capture vibrational, electronic, and vibronic transitions in a single calculation…
Conductivity of an electron coupled to anharmonic phonons
Jonathan H. Fetherolf, Petra Shih, Timothy C. Berkelbach
We study the impact of phonon anharmonicity on the electronic dynamics of soft materials using a nonperturbative quantum-classical approach. The method is applied to a one-dimensio…
Vibrational Heat-Bath Configuration Interaction
Jonathan H. Fetherolf, Timothy C. Berkelbach
We introduce vibrational heat-bath configuration interaction (VHCI) as an accurate and efficient method for calculating vibrational eigenstates of anharmonic systems. Inspired by i…
A unification of the Holstein polaron and dynamic disorder pictures of charge transport in organic semiconductors
Jonathan H. Fetherolf, Denis Golez, Timothy C. Berkelbach
We present a unified and nonperturbative method for calculating spectral and transport properties of Hamiltonians with simultaneous Holstein (diagonal) and Peierls (off-diagonal) e…
Linear and nonlinear spectroscopy from quantum master equations
Jonathan H. Fetherolf, Timothy C. Berkelbach
We investigate the accuracy of the second-order time-convolutionless (TCL2) quantum master equation for the calculation of linear and nonlinear spectroscopies of multichromophore s…
