Quantum Optimal Control Theory
J. Werschnik, E. K. U. Gross
The control of quantum dynamics via specially tailored laser pulses is a long-standing goal in physics and chemistry. Partly, this dream has come true, as sophisticated pulse shapi…
Optimal Control of charge transfer
J. Werschnik, E. K. U. Gross
In this work, we investigate how and to which extent a quantum system can be driven along a prescribed path in space by a suitably tailored laser pulse. The laser field is calculat…
Optimal laser-control of double quantum dots
E. Rasanen, A. Castro, J. Werschnik +2
Coherent single-electron control in a realistic semiconductor double quantum dot is studied theoretically. Using optimal-control theory we show that the energy spectrum of a two-di…
Optimal Control of Quantum Rings by Terahertz Laser Pulses
E. Rasanen, A. Castro, J. Werschnik +2
Complete control of single-electron states in a two-dimensional semiconductor quantum-ring model is established, opening a path into coherent laser-driven single-gate qubits. The c…
Tailoring laser pulses with spectral and fluence constraints using optimal control theory
J. Werschnik, E. K. U. Gross
Within the framework of optimal control theory we develop a simple iterative scheme to determine optimal laser pulses with spectral and fluence constraints. The algorithm is applie…
Time-dependent density functional theory: Past, present, and future
Kieron Burke, Jan Werschnik, E. K. U. Gross
Time-dependent density functional theory (TDDFT) is presently enjoying enormous popularity in quantum chemistry, as a useful tool for extracting electronic excited state energies.…
