Quantum Monte Carlo Calucations Of Three And Six-Quark States
… the quarks. We solve for single baryon S and P-wave spectra by solving the Schrodinger equation variationally for the ground state of three interacting light-flavored valence quarks. The variational Monte Carlo method is then used to find the ground state of six quarks confined to a cavity of …

The ground state of liquid helium-four
… ground state of liquid He-4 are studied using a variational wave function of the form TT f(rij)o The Lennard-Jones 12-6 potential with i<j parameters determined from the gas data by de Boer and Michels is used o The configuration space integrals are performed by the Monte Carlo method of …

Green's function Monte Carlo calculations of few-nucleon systems
… nuclear systems begins with the development of a variational wave function. We discuss the basis for our variational wave functions and the Monte Carlo techniques used to evaluate expectation values with these wave functions. To determine the exact ground state, Green's function Monte Carlo (GFMC) …

Electron impact excitation-ionization of molecules
… have examined the Molecular three-body distorted wave (M3DW) or Molecular four-body distorted wave (M4DW) approximations for electron-impact ionization. These models use a fully quantum mechanical approach where all particles are treated quantum mechanically and the post collision interaction …

Investigating Topological Quantum Matter: Machine Learning Topological Phases, Topological Quantum Codes, Interplay of Disorder and Topology via Transport Phenomena and Phase Transitions
… through a single computational lens that marries variational wave-function design, clause-density-optimal Max-SAT decoding, parameterised quantum-circuit optimisation and disorder-driven band-topology. Part I, casts the spin-1/2 Kitaev honeycomb model into a neural framework by training a …

AB-INITIO DYNAMICS IN STRONGLY INTERACTING MANY-BODY SYSTEMS
… that tackle this problem is the time-dependent variational Monte Carlo (t-VMC), developed by G. Carleo [1, 2]. This method builds on the basic idea of the standard variational Monte Carlo (VMC): the optimization of a variational Ansatz wave function depending on a set of parameters. While the …
