Modified Bloch-Redfield Master Equation for Incoherent Excitation of Multilevel Quantum Systems
Timur V. Tscherbul, Paul Brumer
We present an efficient theoretical method for calculating the time evolution of the density matrix of a multilevel quantum system weakly interacting with incoherent light. The met…
An efficient implementation of the localized operator partitioning method for electronic energy transfer
Jayashree Nagesh, Artur F. Izmaylov, Paul Brumer
The localized operator partitioning method [Y. Khan and P. Brumer, J. Chem. Phys. 137, 194112 (2012)] rigorously defines the electronic energy on any subsystem within a molecule an…
Classical Approach to Multichromophoric Resonance Energy Transfer
Sebastian Duque, Paul Brumer, Leonardo A. Pachon
A classical formulation of the quantum multichromophoric theory of resonance energy transfer is developed on the basis of classical electrodynamics. The theory allows for the ident…
Power enhancement of heat engines via correlated thermalization in multilevel systems
David Gelbwaser-Klimovsky, Wolfgang Niedenzu, Paul Brumer +1
We analyze a heat machine based on a periodically-driven quantum system permanently coupled to hot and cold baths. It is shown that the maximal power output of a degenerate -typ…
Direct Experimental Determination of Spectral Densities of Molecular Complexes
Leonardo A. Pachon, Paul Brumer
Determining the spectral density of a molecular system immersed in a proteomic scaffold and in contact to a solvent is a fundamental challenge in the coarse-grained description of,…
Long-lived quasi-stationary coherences in V-type system driven by incoherent light
Timur V. Tscherbul, Paul Brumer
We present a theoretical study of noise-induced quantum coherences in a model three-level V-type system interacting with incoherent radiation, an important prototype for a wide ran…
Quantum Yields from Stationary States: Cis-Trans Isomerization of Model Retinal
T. V. Tscherbul, P. Brumer
Cis-trans isomerization in retinal, the first step in vision, is often computationally studied from a time dependent viewpoint. Motivation for such studies lies in coherent pulsed…
Influence of Non-Markovian Dynamics in Thermal-Equilibrium Uncertainty-Relations
Leonardo A. Pachon, Johan F. Triana, David Zueco +1
Contrary to the conventional wisdom that deviations from standard thermodynamics originate from the strong coupling to the bath, it is shown that in quantum mechanics, these deviat…
