The role of interparticle interaction and environmental coupling in a two-particle open quantum system
Humberto G. Laguna, Robin P. Sagar, David D. Tempel +1
The effects of bath coupling on an interacting two-particle quantum system are studied using tools from information theory. Shannon entropies of the one (reduced) and two-particle…
Feynman's Clock for open quantum systems
David G. Tempel, Alan Aspuru-Guzik
We show that Feynman's Clock construction, in which the time-evolution of a closed quantum system is encoded as a ground state problem, can be extended to open quantum systems. In…
Computational complexity of time-dependent density functional theory
J. D. Whitfield, M. -H. Yung, D. G. Tempel +2
Time-dependent density functional theory (TDDFT) is rapidly emerging as a premier method for solving dynamical many-body problems in physics and chemistry. The mathematical foundat…
A correlated-polaron electronic propagator: open electronic dynamics beyond the Born-Oppenheimer approximation
John A. Parkhill, Thomas Markovich, David G. Tempel +1
In this work we develop a theory of correlated many-electron dynamics dressed by the presence of a finite-temperature harmonic bath. The theory is based on the ab-initio Hamiltonia…
Introduction to Quantum Algorithms for Physics and Chemistry
Man-Hong Yung, James D. Whitfield, Sergio Boixo +2
In this introductory review, we focus on applications of quantum computation to problems of interest in physics and chemistry. We describe quantum simulation algorithms that have b…
Exciton coherence lifetimes from electronic structure
John Parkhill, David Tempel, Alan Aspuru-Guzik
We model the coherent energy transfer of an electronic excitation within covalently linked aromatic homodimers from first-principles, to answer whether the usual models of the bath…
