Preparation and control of electronic wave packets in neutral molecules via attosecond x-ray processes
Emanuele Rossi, Stasis Chuchurka, Kaushik D. Nanda +3
We present a perturbative framework for computing the dynamics of an electronic wave packet launched by an attosecond x-ray pulse in a neutral molecule. The x-ray pulse excites the…
Non-Markovian dynamics in nonstationary Gaussian baths: a hierarchy of pure states approach
Vladislav Sukharnikov, Stasis Chuchurka, Frank Schlawin
Building on the standard hierarchy of pure states (HOPS) approach, we construct a generalized formulation suitable for open quantum systems interacting with nonstationary Gaussian…
Modelling many-body quantum dynamics with stochastic trajectories: a critical test on the Tavis-Cummings model
A. Leonau, S. Chuchurka, V. Sukharnikov +2
We critically explore the applicability of a recently proposed framework to sample the quantum dynamics of a many-body quantum system interacting with light by stochastic trajector…
Experimental demonstration of attosecond hard X-ray pulses
Ichiro Inoue, River Robles, Aliaksei Halavanau +24
We present the first direct experimental confirmation of attosecond pulse generation in the hard X-ray regime with a free-electron laser. Our experiment is based on measurements of…
Attosecond Inner-Shell Lasing at Angstrom Wavelengths
Thomas M. Linker, Aliaksei Halavanau, Thomas Kroll +34
Since the invention of the laser nonlinear effects such as filamentation, Rabi-cycling and collective emission have been explored in the optical regime leading to a wide range of s…
Experimentally constrained wave function method
Stasis Chuchurka, Milaim Kas, Andrei Benediktovitch +1
In this work, we extend the x-ray constrained wavefunction fitting approach, a key method in quantum crystallography for charge density reconstruction, to incorporate experimental…
