On the Consistency of Approximate Quantum Dynamics Simulation Methods for Vibrational Spectra in the Condensed Phase
Mariana Rossi, Hanchao Liu, Francesco Paesani +2
Including quantum mechanical effects on the dynamics of nuclei in the condensed phase is challenging, because the complexity of exact methods grows exponentially with the number of…
A driven similarity renormalization group approach to quantum many-body problems
Francesco A. Evangelista
Applications of the similarity renormalization group (SRG) approach [F. Wegner, Ann. Phys. 506, 77 (1994), S. D. Głazek and K. G. Wilson, Phys. Rev. D 49, 4214 (1994)] to the formu…
Learning Latent Variable Gaussian Graphical Models
Zhaoshi Meng, Brian Eriksson, Alfred O. Hero
Gaussian graphical models (GGM) have been widely used in many high-dimensional applications ranging from biological and financial data to recommender systems. Sparsity in GGM plays…
Adaptive multiconfigurational wave functions
Francesco A. Evangelista
A method is suggested to build simple multiconfigurational wave functions specified uniquely by an energy cutoff . These are constructed from a model space containing determinan…
