NUMERICAL SIMULATIONS OF THE PHASE TRANSITIONS IN CLUSTERS
We have studied the phase transitions in atomic clusters by molecular dynamics simulation, assuming Lennard-Jones interatomic pair potential. Calculations are performed by DAP parallel computer. The results are analyzed by simulating their orientational distribution plots (dot-plot), and neutron diffraction patterns. It is shown that all the main features of the bulk phase transitions are e...

متن کاملNumerical Simulations of Quantum Phase Transitions
In this talk I will describe some examples of quantum phase transitions with disorder and explain in what ways these transitions diier from conventional phase transitions at nite temperature. It will be explained that the-expansion does not work and so much of what we know has come from numerical simulations. A novel feature is the importance of \Griiths singularities", which come from rare, st...
متن کاملTowards Numerical and Analytical Studies of First Order Phase Transitions A
Discrete lattice simulations of a one-dimensional φ 4 theory coupled to an external heat bath are being carried out. Great care is taken to remove the effects of lattice discreteness and finite size and to establish the correct correspondence between simulations and the desired, finite-temperature continuum limit.
