Proposing a Governance Model for Environmental Crises

Land, 2023
During August 2021, a wildfire outbreak in Evia, Greece’s second largest island, resulted in a major environmental and economic crisis. Apart from biodiversity and habitat loss, the disaster triggered a financial crisis because it wiped out wood ...

Monte Carlo Analysis of a New Interatomic Potential for He

, 1993
By means of a Quadratic Diffusion Monte Carlo method we have performed a comparative analysis between the Aziz potential and a revised version of it. The results demonstrate that the new potential produces a better description of the equation of state ...

Exact Monte Carlo time dynamics in many-body lattice quantum systems [PDF]

, 2004
On the base of a Feynman-Kac--type formula involving Poisson stochastic processes, recently a Monte Carlo algorithm has been introduced, which describes exactly the real- or imaginary-time evolution of many-body lattice quantum systems.

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 ...

Study of a hard-core boson model with ring-only interactions

, 2010
We present a Quantum Monte Carlo study of a hardcore 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.

Large-basis shell-model calculations for p-shell nuclei [PDF]

, 1998
Results of large-basis shell-model calculations for nuclei with A=7-11 are presented. The effective interactions used in the study were derived microscopically from the Reid93 potential and take into account the Coulomb potential as well as the charge ...

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.

Climate Change, Wildfires and Fir Forests in Greece: Perceptions of Forest Managers

South-East European Forestry, 2015
Background and Purpose: The potential impact that climate change may have on fire regime in ecosystems that are not fire-dependent emerges from fires that are nowadays spreading over higher altitudes and northern latitudes. The effects of fire occurrence
