چکیده

A discussion of the Monte Carlo methods for the Ising model highlights the benefits of the Swendsen-Wang algorithm. Next, an a priori model that has been developed for the analytical reconstruction of crystal structures from xray crystallography data is discussed, and the feasibility of developing an algorithm for this model similar to the Swendsen-Wang algorithm is considered.

Monte Carlo Simulation of Prostate Intensity Modulated Radiotherapy Using PRIMO Software: A Feasibility Study

Introduction: Nowadays Intensity Modulated Radiotherapy (IMRT) is a common method for treating prostate cancers. Must of the Monte Carlo software cannot simulate the IMRT procedures due to inability of these soft wares to simulate the multi leaf collimator (MLC) positions or movements. A new user-friendly software based on the PENELOPE Monte Carlo code named PRIMO was published...

The effect of electronic disequilibrium on the received dose by lung in small fields with photon beams: Measurements and Monte Carlo study

Background: Prediction of the absorbed dose in irradiated volume plays an important role in the outcome of radiotherapy. Application of small fields for radiotherapy of thorax makes the dose calculation process inaccurate due to the existence of electronic disequilibrium and intrinsic deficiencies in dose calculation algorithms. To study the lung absorbed dose in radiotherapy with smal...

Enhanced laser cooling and state preparation in an optical lattice with a magnetic field

We demonstrate that weak magnetic fields can significantly enhance laser cooling and state preparation of Cs atoms in a one-dimensional optical lattice. A field parallel to the lattice axis increases the vibrational groundstate population of the stretched state um5F& to 28%. A transverse field reduces the kinetic temperature. Quantum Monte Carlo simulations agree with the experiment, and predic...
