Approaching chemical accuracy with quantum Monte Carlo.

A quantum Monte Carlo study of the atomization energies for the G2 set of molecules is presented. Basis size dependence of diffusion Monte Carlo atomization energies is studied with a single determinant Slater-Jastrow trial wavefunction formed from Hartree-Fock orbitals. With the largest basis set, the mean absolute deviation from experimental atomization energies for the G2 set is 3.0 kcal/mol...

Approaching the Ground State of a Quantum Spin Glass using a Zero-Temperature Quantum Monte Carlo

Here we discuss the annealing behavior of an infinite-range ±J Ising spin glass in presence of a transverse field using a zero-temperature quantum Monte Carlo. Within the simulation scheme, we demonstrate that quantum annealing not only helps finding the ground state of a classical spin glass, but can also help simulating the ground state of a quantum spin glass, in particularly, when the trans...

Quantum Monte Carlo for High Accuracy ab initio Calculations

Quantum Monte Carlo (QMC) is among the most accurate ab initio Quantum Chemistry methods available. Furthermore, in stark contrast with comparable methods, it is trivially parallelizable, it requires only a negligible amount of memory, and it’s computational cost scales as only O(N^3). Unfortunately, as a stochastic method, it requires a sizeable number of state space evaluations. We have been ...

Rapid Design Iterations with Monte Carlo Accuracy

This chapter explores how to efficiently design circuits accounting for statistical process variation, with target yields of two to three sigma (95–99.86 %). This yield range is appropriate for typical analog, RF, and I/O circuits. This chapter reviews various design flows to handle statistical process variations, and compares these flows in terms of speed and accuracy. It shows how a sigma-dri...
