Multilayer multi-configuration time-dependent Hartree method: implementation and applications to a Henon-Heiles Hamiltonian and to pyrazine
Oriol Vendrell,Hans-Dieter Meyer +1 more
TL;DR: Results of similar quality than the best available MCTDH benchmark, which is based on a wavepacket with 4.6×10(7)time-dependent coefficients, are obtained with a much more compact wavefunction consisting of only 4.5× 10(5) coefficients and requiring a shorter computation time.
Journal ArticleDOI
Multilayer multiconfiguration time-dependent Hartree method: implementation and applications to a Henon-Heiles hamiltonian and to pyrazine.
Oriol Vendrell,Hans-Dieter Meyer +1 more
TL;DR: In this article, the multilayer multiconfiguration time-dependent Hartree (ML-MCTDH) method is discussed and a fully general implementation for any number of layers based on the recursive MCTDH algorithm given by Manthe [J. Phys.
Journal ArticleDOI
Ultrafast electron diffraction imaging of bond breaking in di-ionized acetylene
Benjamin Wolter,M. G. Pullen,Anh-Thu Le,Matthias Baudisch,Katharina Doblhoff-Dier,Arne Senftleben,Michael Hemmer,C. D. Schröter,J. Ullrich,J. Ullrich,Thomas Pfeifer,Robert Moshammer,Stefanie Gräfe,Oriol Vendrell,Chi Lin,Jens Biegert,Jens Biegert +16 more
TL;DR: Using mid-infrared laser–induced electron diffraction (LIED), the molecular structure of acetylene (C2H2) is imaged 9 femtoseconds after ionization and measurements are in excellent agreement with a quantum chemical description of field-dressed molecular dynamics.
Journal ArticleDOI
Full dimensional (15-dimensional) quantum-dynamical simulation of the protonated water dimer. II. Infrared spectrum and vibrational dynamics.
TL;DR: The infrared absorption spectrum of the protonated water dimer (H5O2+) is simulated in full dimensionality (15 dimensional) in the spectral range of 0-4000 cm(-1) using the MCTDH method for propagation of wavepackets.
