CP2K: An electronic structure and molecular dynamics software package - Dynamics, Transport, and Spectroscopic Response
Jan Wilhelm, Anna-Sophia Hehn, Anna Hehn +40
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…
