The dark side of energy transport along excitonic wires: On-site energy barriers facilitate efficient, vibrationally-mediated transport through optically dark subspaces
Scott Davidson, Amir Fruchtman, Felix Pollock +1
We present a novel, counter-intuitive method, based on dark state protection, for significantly improving exciton transport efficiency through `wires' comprising a chain of molecul…
When do weak-coupling approaches accurately capture the dynamics of complex quantum systems?
Amir Fruchtman, Neill Lambert, Erik M. Gauger
Understanding the dynamics of higher-dimensional quantum systems embedded in a complex environment remains a significant theoretical challenge. While several approaches yielding nu…
Photocell Optimisation Using Dark State Protection
Amir Fruchtman, Rafael Gómez-Bombarelli, Brendon W. Lovett +1
Conventional photocells suffer a fundamental efficiency threshold imposed by the principle of detailed balance, reflecting the fact that good absorbers must necessarily also be fas…
Quantum dynamics in a tiered non-Markovian environment
Amir Fruchtman, Brendon W. Lovett, Simon C. Benjamin +1
We introduce a new analytical method for studying the open quantum systems problem of a discrete system weakly coupled to an environment of harmonic oscillators. Our approach is ba…
Single vortex fluctuations in a superconducting chip as generating dephasing and spin flips in cold atom traps
Amir Fruchtman, Baruch Horovitz
We study trapping of a cold atom by a single vortex line in an extreme type II superconducting chip, allowing for pinning and friction. We evaluate the atom's spin flip rate and it…
