CP2K: An electronic structure and molecular dynamics software package - Dynamics, Transport, and Spectroscopic Response
Jan Wilhelm, Anna-Sophia Hehn, Hossam Elgabarty +39
One of the distinguishing aspects of CP2K is its seamless integration of diverse structural and transition-state optimization techniques with advanced sampling approaches including…
Terahertz-induced local-field dynamics and transient birefringence in aqueous electrolytes
Naveen Kumar Kaliannan, Thomas D. Kühne, Hossam Elgabarty
Terahertz Kerr-effect (TKE) spectroscopy provides a time-domain optical probe of the intermolecular structural dynamics of liquids, but the measured birefringence can only be inter…
Accelerated "on-the-fly" coupled-cluster path-integral molecular dynamics: Impact of nuclear quantum effects on an asymmetric proton
Thomas Spura, Hossam Elgabarty, Thomas D. Kühne
We present an accelerated ``on-the-fly'' coupled-cluster path-integral molecular dynamics (PIMD) method for finite-temperature simulations in which electron correlation and nuclear…
The CP2K Program Package Made Simple
Marcella Iannuzzi, Jan Wilhelm, Frederick Stein +24
CP2K is a versatile open-source software package for simulations across a wide range of atomistic systems, from isolated molecules in the gas phase to low-dimensional functional ma…
Benchmarking semi-empirical quantum chemical methods on liquid water
Xin Wu, Hossam Elgabarty, Vahideh Alizadeh +6
Stimulated by the renewed interest and recent developments in semi-empirical quantum chemical (SQC) methods for noncovalent interactions, we examine the properties of liquid water…
Ultrafast two-colour X-ray emission spectroscopy reveals excited state landscape in a base metal dyad
Michal Nowakowski, Marina Huber-Gedert, Hossam Elgabarty +15
Effective photoinduced charge transfer makes molecular bimetallic assemblies attractive for applications as active light induced proton reduction systems. For a more sustainable fu…
Breaking the Exascale Barrier for the Electronic Structure Problem in Ab-Initio Molecular Dynamics
Robert Schade, Tobias Kenter, Hossam Elgabarty +3
The non-orthogonal local submatrix method applied to electronic-structure based molecular dynamics simulations is shown to exceed 1.1 EFLOP/s in FP16/FP32 mixed floating-point arit…
Towards Electronic Structure-Based Ab-Initio Molecular Dynamics Simulations with Hundreds of Millions of Atoms
Robert Schade, Tobias Kenter, Hossam Elgabarty +8
We push the boundaries of electronic structure-based \textit{ab-initio} molecular dynamics (AIMD) beyond 100 million atoms. This scale is otherwise barely reachable with classical…
Mixed-valence compounds as polarizing agents for Overhauser dynamic nuclear polarization in solids
Andrei Gurinov, Benedikt Sieland, Andrei Kuzhelev +7
In this paper we investigate a novel set of polarizing agents -- mixed-valence compounds -- by theoretical and experimental methods and demonstrate their performance in high-field…
Energy Transfer within the Hydrogen Bonding Network of Water Following Resonant Terahertz Excitation
Hossam Elgabarty, Tobias Kampfrath, Douwe Jan Bonthuis +7
Energy dissipation in water is very fast and more efficient than in many other liquids. This behavior is commonly attributed to the intermolecular interactions associated with hydr…
Tumbling with a Limp: Local Asymmetry in Water's Hydrogen Bond Network and its Consequences
Hossam Elgabarty, Thomas D. Kühne
Ab initio molecular dynamics simulations of liquid water under equilibrium ambient conditions, together with a novel energy decomposition analysis, have recently shown that a subst…
Structure and Dynamics of the Instantaneous Water/Vapor Interface Revisited by Path-Integral and Ab-Initio Molecular Dynamics Simulations
Jan Kessler, Hossam Elgabarty, Thomas Spura +4
The structure and dynamics of the water/vapor interface is revisited by means of path-integral and second-generation Car-Parrinello ab-initio molecular dynamics simulations in conj…
