Quantum Monte Carlo calculations of weak transitions in $A\,$=$\,$6--10 nuclei

, 2017
Ab initio calculations of the Gamow-Teller (GT) matrix elements in the $\beta$ decays of $^6$He and $^{10}$C and electron captures in $^7$Be are carried out using both variational and Green's function Monte Carlo wave functions obtained from the Argonne $

Superfluid to Mott-insulator transition in Bose-Hubbard models

, 2007
We study the superfluid-insulator transition in Bose-Hubbard models in one-, two-, and three-dimensional cubic lattices by means of a recently proposed variational wave function.

World-Line Path Integral Study of Supersymmetry Breaking in the Wess-Zumino Model

, 2003
We study supersymmetry breaking in the lattice N=1 Wess-Zumino model by the world-line path integral algorithm. The ground state energy and supersymmetric Ward identities are exploited to support the expected symmetry breaking in finite volume.

Spin-averaged $B_c$ Spectrum in a Cornell-type Potential Using VMC Baseline and GFMC Evolution

In this work, the spin-averaged $B_c$ spectrum is computed in a naive Cornell framework, treating the meson as a nonrelativistic system in a spin-independent potential. The Cornell parameters are calibrated directly to the spin-averaged $B_c$ tower by anchoring the $1S$ centroid and scanning a grid in $(σ,κ)$, with the additive constant $V_0$ fixed at ...

Zero-Temperature Properties of the Quantum Dimer Model on the Triangular Lattice

, 2005
Using exact diagonalizations and Green's function Monte Carlo simulations, we have studied the zero-temperature properties of the quantum dimer model on the triangular lattice on clusters with up to 588 sites.

Properties of nuclei up to $A=16$ using local chiral interactions

, 2018
We report accurate quantum Monte Carlo calculations of nuclei up to $A=16$ based on local chiral two- and three-nucleon interactions up to next-to-next-to-leading order.

Oscillation Suppression of Grid-Following Converters by Grid-Forming Converters with Adaptive Droop Control

Energies
The high penetration of renewable energy sources (RESs) and power electronics devices has led to a continuous decline in power system stability. Due to the instability of grid-following converters (GFLCs) in weak grids, the grid-forming converters (GFMCs)
