Excited State-Specific CASSCF Theory for the Torsion of Ethylene
State-specific complete active space self-consistent field (SS-CASSCF) theory has emerged as a promising route to accurately predict electronically excited energy surfaces away from molecular equilibria. However, its accuracy and practicality for chemical ...
Amer Chemical Soc2024Verification of the Fourier-enhanced 3D finite element Poisson solver of the gyrokinetic full-f code PICLS
Laurent Villard, Stephan Brunner, Alberto Bottino, Moahan Murugappan
We introduce and derive the Fourier -enhanced 3D electrostatic field solver of the gyrokinetic full -f PIC code PICLS. The solver makes use of a Fourier representation in one periodic direction of the domain to make the solving of the system easily paralle ...
Elsevier2024A Spectral Ansatz for The Long-Time Homogenization of The Wave Equation
- Consider the wave equation with heterogeneous coefficients in the homogenization regime. At large times, the wave interacts in a nontrivial way with the heterogeneities, giving rise to effective dispersive effects. The main achievement of the present wor ...
Spin, Charge, and ?-Spin Separation in One-Dimensional Photodoped Mott Insulators
We show that effectively cold metastable states in one-dimensional photodoped Mott insulators described by the extended Hubbard model exhibit spin, charge, and q-spin separation. Their wave functions in the large on-site Coulomb interaction limit can be ex ...
AMER PHYSICAL SOC2023Application of ray methods to one-dimensional site response of inhomogeneous soil deposits
The technique referred as ray approximation treats wave propagation in a heterogeneous medium at the infinitely small wavelength limit. This classic simplification allows useful approximate analytical results to be obtained in cases where complete descript ...
2022Function Integration, Reconstruction And Approximation Using Rank-1 Lattices
Fabio Nobile, Giovanni Migliorati
We consider rank-1 lattices for integration and reconstruction of functions with series expansion supported on a finite index set. We explore the connection between the periodic Fourier space and the non-periodic cosine space and Chebyshev space, via tent ...
