Understanding Quantum Tunneling through Quantum Monte Carlo Simulations.
The tunneling between the two ground states of an Ising ferromagnet is a typical example of many-body tunneling processes between two local minima, as they occur during quantum annealing. Performing quantum Monte Carlo (QMC) simulations we find that the QMC tunneling rate displays the same scaling with system size, as the rate of incoherent tunneling. The scaling in both cases is O(Δ^{2}), wher...
متن کاملAram Harrow - Quantum Monte Carlo vs Tunneling in Adiabatic Optimization
In this talk I'll present a quantum algorithm for solving semidefinite programs (SDPs). It has worst case running time O((nm)^1/2 r), with n and r the dimension and sparsity of the input matrices, respectively, and m the number of constraints. In contrast any classical method requires at least Omega(nm) time to solve the problem. I'll discuss how for some instances the algorithm might offer eve...
متن کاملQuantum Monte Carlo Calculation for the neutron-rich Ca isotopes
We computed ground-state energies of calcium isotopes from Ca to Ca by means of the Auxiliary Field Diffusion Monte Carlo (AFDMC) method. Calculations were performed by replacing the Ca core with a mean-field self consistent potential computed using Skyrme interaction. The energy of the external neutrons is calculated by projecting the ground-state from a wave function built with the single par...
متن کاملMultiorbital Hubbard model in infinite dimensions: Quantum Monte Carlo calculation
Using the quantum Monte Carlo technique we compute thermodynamics and spectra for the orbitally degenerate Hubbard model in infinite spatial dimensions. With increasing orbital degeneracy we find in the one-particle spectra broader Hubbard bands ~consistent with increased kinetic energy!, a narrowing Mott gap, and increasing quasiparticle spectral weight. Hund’s rule exchange coupling decreases...
متن کاملQuantum Monte Carlo calculation of Compton profiles of solid lithium
Recent high-resolution Compton scattering experiments in lithium have shown significant discrepancies with conventional band theoretical results. We present a pseudopotential quantum Monte Carlo study of electronelectron and electron-ion correlation effects on the momentum distribution of lithium. We compute the correlation correction to the valence Compton profiles obtained within Kohn-Sham de...
