Finite groups with many -regular conjugacy classes
Christopher A. Schroeder
Let be a finite group and let be a prime. In this paper, we study the structure of finite groups with a large number of -regular conjugacy classes or, equivalently, a la…
Optical signatures of quantum delocalization over extended domains in photosynthetic membranes
Christopher A. Schroeder, Felipe Caycedo-Soler, Susana F. Huelga +1
The prospect of coherent dynamics and excitonic delocalization across several light-harvesting structures in photosynthetic membranes is of considerable interest, but challenging t…
Quantum redirection of antenna absorption to photosynthetic reaction centres
Felipe Caycedo-Soler, Christopher A. Schroeder, Caroline Autenrieth +4
The early steps of photosynthesis involve the photo-excitation of reaction centres (RCs) and light-harvesting (LH) units. Here, we show that the --historically overlooked-- exciton…
Feedback in a cavity QED system for control of quantum beats
A. D. Cimmarusti, B. D. Patterson, C. A. Schroeder +3
Conditional measurements on the undriven mode of a two-mode cavity QED system prepare a coherent superposition of ground states which generate quantum beats. The continuous system…
Control of conditional quantum beats in cavity QED: amplitude decoherence and phase shifts
A. D. Cimmarusti, C. A. Schroeder, B. D. Patterson +3
We implement a simple feedback mechanism on a two-mode cavity QED system to preserve the Zeeman coherence of a ground state superposition that generates quantum beats on the second…
Optimized pulse sequences for suppressing unwanted transitions in quantum systems
C. A. Schroeder, G. S. Agarwal
We investigate the nature of the pulse sequence so that unwanted transitions in quantum systems can be inhibited optimally. For this purpose we show that the sequence of pulses pro…
