Bubble flow analysis using multi-phase field method [PDF]
EPJ Web of ConferencesIn simulations of gas-liquid two-phase flows using conventional interface capture methods, we observed that when bubbles come close to each other, they tend to merge numerically, despite experimental evidence indicating that they would repel each other ...

Phase diagram of an anisotropic frustrated ferromagnetic spin-1/2 chain in a magnetic field: a density matrix renormalization group study [PDF]
, 2009 We study the phase diagram of a frustrated spin-1/2 ferromagnetic chain with anisotropic exchange interactions in an external magnetic field, using the density matrix renormalization group method.

Simulation of Dendritic-Eutectic Growth with the Phase-Field Method
Acta Materialia, 2023 Solidification is an important process in many alloy processing routes. The solidified microstructure of alloys is usually made up of dendrites, eutectics or a combination of both. The evolving morphologies are largely determined by the solidification process and thus many materials properties are dependent on the processing conditions.

Austenite grain growth simulation considering the solute-drag effect and pinning effect
Science and Technology of Advanced Materials, 2017 The pinning effect is useful for restraining austenite grain growth in low alloy steel and improving heat affected zone toughness in welded joints. We propose a new calculation model for predicting austenite grain growth behavior.

Phase-field simulation of core-annular pipe flow
, 2019 Phase-field methods have long been used to model the flow of immiscible fluids. Their ability to naturally capture interface topological changes is widely recognized, but their accuracy in simulating flows of real fluids in practical geometries is not ...

Phase-field methods for spectral shape and topology optimization
ESAIM: Control, Optimisation and Calculus of Variations, 2023 We optimize a selection of eigenvalues of the Laplace operator with Dirichlet or Neumann boundary conditions by adjusting the shape of the domain on which the eigenvalue problem is considered. Here, a phase-field function is used to represent the shapes over which we minimize. The idea behind this method is to modify the Laplace operator by introducing

Quantum trajectory approach to stochastically-induced quantum interference effects in coherently-driven two-level atoms [PDF]
, 2002 Stochastic perturbation of two-level atoms strongly driven by a coherent light field is analyzed by the quantum trajectory method. A new method is developed for calculating the resonance fluorescence spectra from numerical simulations.
