Measurement of the minimum cold dark matter halo mass with strong gravitational lensing
A. M. Nierenberg, D. Gilman, T. Treu +19
We explore the lowest mass limit that can be placed on the halo mass function in CDM using 28 strong gravitational lenses. For this purpose, we study an extreme model in which the…
JWST Lensed Quasar Dark Matter Survey III: Dark Matter Sensitive Flux Ratios and Warm Dark Matter Constraint from the Full Sample
R. E. Keeley, A. M. Nierenberg, D. Gilman +24
We present the full sample of measurements of the warm dust emission of 31 strongly-lensed, multiply imaged quasars, observed with JWST MIRI multiband imaging, which we use to cons…
Simulating real-time molecular electron dynamics efficiently using the time-dependent density matrix renormalization group
Imam S. Wahyutama, Henrik R. Larsson
Compared to ground state electronic structure optimizations, accurate simulations of molecular real-time electron dynamics are usually much more difficult to perform. To simulate e…
2500 vibronic eigenstates of the NO radical
Henrik R. Larsson, Alexandra Viel
The nitrate radical NO plays an important role in atmospheric chemistry, yet many aspects of its coupled and anharmonic vibronic structure remain elusive. Here, using an accura…
Block2: a comprehensive open source framework to develop and apply state-of-the-art DMRG algorithms in electronic structure and beyond
Huanchen Zhai, Henrik R. Larsson, Seunghoon Lee +10
Block2 is an open source framework to implement and perform density matrix renormalization group and matrix product state algorithms. Out-of-the-box it supports the eigenstate, tim…
State-resolved infrared spectrum of the protonated water dimer: Revisiting the characteristic proton transfer doublet peak
Henrik R. Larsson, Markus Schröder, Richard Beckmann +4
The infrared (IR) spectra of protonated water clusters encode precise information on the dynamics and structure of the hydrated proton. However, the strong anharmonic coupling and…
The chromium dimer: closing a chapter of quantum chemistry
Henrik R. Larsson, Huanchen Zhai, C. J. Umrigar +1
The complex electronic structure and unusual potential energy curve of the chromium dimer have fascinated scientists for decades, with agreement between theory and experiment so fa…
Matrix product states with large sites
Henrik R. Larsson, Huanchen Zhai, Klaas Gunst +1
We explore various ways to group orbitals into clusters in a matrix product state (MPS). We explain how a generic cluster MPS can often lead to an increase in computational cost an…
Minimal matrix product states and generalizations of mean-field and geminal wavefunctions
Henrik R. Larsson, Carlos A. Jiménez-Hoyos, Garnet Kin-Lic Chan
Simple wavefunctions of low computational cost but which can achieve qualitative accuracy across the whole potential energy surface (PES) are of relevance to many areas of electron…
Control of concerted back-to-back double ionization dynamics in helium
Henrik R. Larsson, David J. Tannor
Double ionization (DI) is a fundamental process that despite its apparent simplicity provides rich opportunities for probing and controlling the electronic motion. Even for the sim…
Global optimization of parameters in the reactive force field ReaxFF for SiOH
H. R. Larsson, A. C. T. van Duin, B. Hartke
We have used unbiased global optimization to fit a reactive force field to a given set of reference data. Specifically, we have employed genetic algorithms (GA) to fit ReaxFF to Si…
Computing vibrational eigenstates with tree tensor network states (TTNS)
Henrik R. Larsson
We present how to compute vibrational eigenstates with tree tensor network states (TTNSs), the underlying ansatz behind the multilayer multiconfiguration time-dependent Hartree (ML…
