Diffusion Monte Carlo study of two-dimensional liquid $^4$He

, 1995
The ground-state properties of two-dimensional liquid $^4$He at zero temperature are studied by means of a quadratic diffusion Monte Carlo method. As interatomic potential we use a revised version of the HFDHE2 Aziz potential which is expected to give a ...

Concept for Integrated Fire Management on Terrain Contaminated by Radionuclides in the Chornobyl Exclusion Zone

Biodiversidade Brasileira, 2019
A concept for Integrated Fire Management (IFM) on terrain contaminated by radionuclides in the Chornobyl Exclusion Zone (CEZ) was developed within cooperative efforts of the U.S.

Ab initio calculations of nuclear widths via an integral relation

, 2012
I describe the computation of energy widths of nuclear states using an integral over the interaction region of ab initio variational Monte Carlo wave functions, and I present calculated widths for many states. I begin by presenting relations that connect

Identification of an RVB liquid phase in a quantum dimer model with competing kinetic terms

, 2006
Starting from the mean-field solution of a spin-orbital model of LiNiO$_2$, we derive an effective quantum dimer model (QDM) that lives on the triangular lattice and contains kinetic terms acting on 4-site plaquettes and 6-site loops.

Path Integral Ground State with a Fourth-Order Propagator: Application to Condensed Helium

, 2005
Ground state properties of condensed Helium are calculated using the Path Integral Ground State (PIGS) method. A fourth-order approximation is used as short (imaginary) time propagator.

Ground State Properties of Fermi Gases in the Strongly Interacting Regime

, 2005
The ground state energies and pairing gaps in dilute superfluid Fermi gases have now been calculated with the quantum Monte Carlo method without detailed knowledge of their wave functions.

Doping quantum dimer models on the square lattice

, 2006
A family of models is proposed to describe the motion of holes in a fluctuating quantum dimer background on the square lattice. Following Castelnovo et al. [Ann. Phys. (NY) 318, 316 (2005)], a generalized Rokhsar-Kivelson Hamiltonian at **finite doping**

Metal-insulator transition in the one-dimensional SU(N) Hubbard model

, 1999
We investigate the metal-insulator transition of the one-dimensional SU(N) Hubbard model for repulsive interaction. Using the bosonization approach a Mott transition in the charge sector at half-filling (k_F=\pi/Na_0) is conjectured for N > 2 ...

Theoretical constraints for the magnetic-dimer transition in two-dimensional spin models

, 2005
From general arguments, that are valid for spin models with sufficiently short-range interactions, we derive strong constraints on the excitation spectrum across a continuous phase transition at zero temperature between a magnetic and a dimerized phase ...
