An Approach to "Quantumness" in Coherent Control
Torsten Scholak, Paul Brumer
Developments in the foundations of quantum mechanics have identified several attributes and tests associated with the "quantumness" of systems, including entanglement, nonlocality,…
The Spectral Backbone of Excitation Transport in Ultra-Cold Rydberg Gases
Torsten Scholak, Thomas Wellens, Andreas Buchleitner
The spectral structure underlying excitonic energy transfer in ultra-cold Rydberg gases is studied numerically, in the framework of random matrix theory, and via self-consistent di…
Certifying The Quantumness of A Generalized Coherent Control Scenario
Torsten Scholak, Paul Brumer
We consider the role of quantum mechanics in a specific coherent control scenario, designing a "coherent control interferometer" as the essential tool that links coherent control t…
The optimization topography of exciton transport
Torsten Scholak, Thomas Wellens, Andreas Buchleitner
Stunningly large exciton transfer rates in the light harvesting complex of photosynthesis, together with recent experimental 2D spectroscopic data, have spurred a vivid debate on t…
Efficient and coherent excitation transfer across disordered molecular networks
Torsten Scholak, Fernando de Melo, Thomas Wellens +2
We show that finite-size, disordered molecular networks can mediate highly efficient, coherent excitation transfer which is robust against ambient dephasing and associated with str…
Entanglement Witnesses from Single-Particle Interference
T. Scholak, F. Mintert, C. A. Müller
We describe a general method of realizing entanglement witnesses in terms of the interference pattern of a single quantum probe. After outlining the principle, we discuss specific…
