Unitary Fermi Gas in a Harmonic Trap [PDF]
, 2007 We present an {\it ab initio} calculation of small numbers of trapped, strongly interacting fermions using the Green's Function Monte Carlo method (GFMC). The ground state energy, density profile and pairing gap are calculated for particle numbers $N = 2

Quantum Monte Carlo Calculations of Neutron Matter [PDF]
, 2003 Uniform neutron matter is approximated by a cubic box containing a finite number of neutrons, with periodic boundary conditions. We report variational and Green's function Monte Carlo calculations of the ground state of fourteen neutrons in a periodic ...

Possible realization of the Exciton Bose Liquid phase in a hard-core boson model with ring-only exchange interactions [PDF]
, 2010 We investigate a hard-core boson model with ring-only exchanges on a square lattice, where a $K_1$ term acts on 1$\times$1 plaquettes and a $K_2$ term acts on 1$\times$2 and 2$\times$1 plaquettes, with a goal of realizing a novel Exciton Bose Liquid (EBL)

Can Modern Nuclear Hamiltonians Tolerate a Bound Tetraneutron? [PDF]
, 2003 I show that it does not seem possible to change modern nuclear Hamiltonians to bind a tetraneutron without destroying many other successful predictions of those Hamiltonians.

Biodiversidade Brasileira, 2016 In large parts of temperate-boreal Eurasia the use of fire, including historic slash-and-burn (shifting) agriculture and other disturbances by land cultivation have contributed to shape landscape patterns of high ecological and cultural diversity and ...

Biodiversidade Brasileira, 2019 Landscape fires and excessive use of fire in land use and land-use change have become one of the most important issues in Southeast Asia for about 25 years. The impacts of fires result not only in environmental destruction with adverse effects on health

Modified magnetic anisotropy at LaCoO3/La0.7Sr0.3MnO3 interfaces
APL Materials, 2017 Controlling magnetic anisotropy is an important objective towards engineering novel magnetic device concepts in oxide electronics. In thin film manganites, magnetic anisotropy is weak and it is primarily determined by the substrate, through induced ...

Quantum Monte Carlo Calculations of Light Nuclei Using Chiral Potentials
, 2014 We present the first Green's function Monte Carlo calculations of light nuclei with nuclear interactions derived from chiral effective field theory up to next-to-next-to-leading order. Up to this order, the interactions can be constructed in a local form

Media coverage of Wildlife affected by Wildfires in brazilian protected areas
Biodiversidade Brasileira, 2019 Brazil is host of almost 120,000 animal species and therefore classified as "megadiverse". Although fire is a natural agent in some Brazilian ecosystems and fauna historically evolved with its presence, nowadays it can be a potential hazard to fauna ...
