Non-Markovianity in the optimal control of an open quantum system described by hierarchical equations of motion
Etienne Mangaud, Raijumon Puthumpally-Joseph, Dominique Sugny +3
Optimal control theory is implemented with fully converged hierarchical equations of motion (HEOM) describing the time evolution of an open system density matrix strongly coupled t…
Basic mechanisms in the laser control of non-Markovian dynamics
Raiju Puthumpally-Joseph, Etienne Mangaud, Vincent Chevet +3
Referring to a Fano-type model qualitative analogy we develop a comprehensive basic mechanism for the laser control of the non-Markovian bath response in strongly coupled Open Quan…
Extracting spectroscopic molecular parameters from short pulse photo-electron angular distributions
R. Chamakhi, R. Puthumpally-Joseph, M. Telmini +1
Using a quantum wave packet simulation including the nuclear and electronic degrees of freedom, we investigate the femtosecond and picosecond energy- and angle-resolved photoelectr…
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…
Laser-Induced Electron Diffraction: Alignment Defects and Symmetry Breaking
T. T. Nguyen-Dang, M. Peters, J. Viau-Trudel +4
The fringe pattern that allows geometrical and orbital structure information to be extracted from LIED spectra of symmetric molecules is shown to reflect a symmetry conservation pr…
Laser-Induced Electron Diffraction: Inversion of Photoelectron Spectra for Molecular Orbital Imaging
R. Puthumpally-Joseph, J. Viau-Trudel, M. Peters +3
In this paper, we discuss the possibility of imaging molecular orbitals from photoelectron spectra obtained via Laser Induced Electron Diffraction (LIED) in linear molecules. This…
Inversion of Strong Field Photoelectron Spectra for Molecular Orbital Imaging
R. Puthumpally-Joseph, J. Viau-Trudel, M. Peters +3
Imaging structures at the molecular level is a fast developing interdisciplinary research field that spans across the boundaries of physics and chemistry. High spatial resolution i…
Non-Hermitian wave packet approximation for coupled two-level systems in weak and intense fields
Raiju Puthumpally-Joseph, Maxim Sukharev, Eric Charron
We introduce an accurate non-Hermitian Schrödinger-type approximation of Bloch optical equations for two-level systems. This approximation provides a complete description of the ex…
Theory of Dipole Induced Electromagnetic Transparency
Raiju Puthumpally-Joseph, Osman Atabek, Maxim Sukharev +1
A detailed theory describing linear optics of vapors comprised of interacting multi-level quantum emitters is proposed. It is shown both by direct integration of Maxwell-Bloch equa…
Dipole-Induced Electromagnetic Transparency
Raiju Puthumpally-Joseph, Maxim Sukharev, Osman Atabek +1
We determine the optical response of a thin and dense layer of interacting quantum emitters. We show that in such a dense system, the Lorentz redshift and the associated interactio…
