Geometric Origin of the Tennis Racket Effect
P. Mardesic, L. Van Damme, G. J. Gutierrez Guillen +1
The tennis racket effect is a geometric phenomenon which occurs in a free rotation of a three-dimensional rigid body. In a complex phase space, we show that this effect originates…
Robust control of a NOT gate by composite pulses
G. Dridi, M. Mejatty, S. J. Glaser +1
We present a general procedure to implement a NOT gate by composite pulses robust against both offset uncertainties and control field variations. We define different degrees of rob…
Shaping of the time-evolution of field-free molecular orientation by THz laser pulses
R. Tehini, K. Hamraoui, D. Sugny
We present a theoretical study of the shaping of the time-evolution of field-free orientation of linear molecules. We show the extend to which the degree of orientation can be stee…
Towards Laser Control of Open Quantum Systems: Memory Effects
R. Puthumpally-Joseph, O. Atabek, E. Mangaud +2
Laser control of Open Quantum Systems (OQS) is a challenging issue as compared to its counterpart in isolated small size molecules, basically due to very large numbers of degrees o…
On the observation of field-free orientation of a symmetric top molecule by terahertz laser pulses at high temperature
P. Babilotte, K. Hamraoui, F. Billard +4
We investigate experimentally and numerically the field-free orientation of the symmetric top molecule of methyl-iodide at high temperature using a terahertz radiation generated by…
The tennis racket effect in a three-dimensional rigid body
L. Van Damme, P. Mardesic, D. Sugny
We propose a complete theoretical description of the tennis racket effect, which occurs in the free rotation of a three-dimensional rigid body. This effect is characterized by a fl…
Control of molecular dynamics with zero-area fields: Application to molecular orientation and photofragmentation
D. Sugny, Stéphane Vranckx, Mamadou Ndong +3
The constraint of time-integrated zero-area on the laser field is a fundamental, both theoretical and experimental requirement in the control of molecular dynamics. By using techni…

Elie Assémat, Thomas Chambrion, Dominique Sugny
We analyze the control by electromagnetic fields of quantum systems with infinite dimensional Hilbert space and a discrete spectrum. Based on recent mathematical results, we rigoro…
External constraints on optimal control strategies in molecular orientation and photofragmentation: Role of zero-area fields
D. Sugny, S. Vranckx, M. Ndong +2
We propose a new formulation of optimal and local control algorithms which enforces the constraint of time-integrated zero-area on the control field. The fulfillment of this requir…
Time optimization and state-dependent constraints in the quantum optimal control of molecular orientation
M. Ndong, C. Koch, D. Sugny
We apply two recent generalizations of monotonically convergent optimization algorithms to the control of molecular orientation by laser fields. We show how to minimize the control…
Comparative study of monotonically convergent optimization algorithms for the control of molecular rotation
M. Ndong, M. Lapert, C. Koch +1
We apply two different monotonically convergent optimization algorithms to the control of molecular rotational dynamics by laser pulses. This example represents a quantum control p…
A connection between optimal control theory and adiabatic passage techniques in quantum systems
E. Assémat, D. Sugny
This work explores the relationship between optimal control theory and adiabatic passage techniques in quantum systems. The study is based on a geometric analysis of the Hamiltonia…
Dynamics of mixed classical-quantum systems, geometric quantization and coherent states
H. R. Jauslin, D. Sugny
We describe quantum and classical Hamiltonian dynamics in a common Hilbert space framework, that allows the treatment of mixed quantum-classical systems. The analysis of some examp…
Saturation of a spin 1/2 particle by generalized Local control
F. Mintert, M. Lapert, Y. Zhang +2
We show how to apply a generalization of Local control design to the problem of saturation of a spin 1/2 particle by magnetic fields in Nuclear Magnetic Resonance. The generalizati…
