A modified damage and fracture phase field model considering heterogeneity for rock‐like materials
Deep Underground Science and Engineering, 2023 Damage and fracture are the most extensive failure modes of rock materials, which may easily induce disaster and instability of engineering structures.

Unified derivation of phase-field models for alloy solidification from a grand-potential functional
, 2011 In the literature, two quite different phase-field formulations for the problem of alloy solidification can be found. In the first, the material in the diffuse interfaces is assumed to be in an intermediate state between solid and liquid, with a unique ...

Density waves in quasi-one-dimensional atomic gas mixture of boson and two-component fermion
, 2005 We study the density-wave states of quasi-one-dimensional atomic gas mixture of one- and two-component boson and fermion using the mean-field approximation. Owing to the Peierls instability in the quasi-one-dimensional fermion system, the ground state of

Magnetoresistances observed by decomposition of the magnetic moment in La1-xCaxMnO3 films
, 2002 A ferromagnetic phase, characterized by electron carriers and a high temperature colossal magnetoresistance (HTCMR) dependent on the magnetic moment, and a semiconducting phase, characterized by hole carriers and a low temperature CMR (LTCMR), are ...

Phase-field modeling of thermo-mechanical coupled brittle fracture for transversely isotropic rock
Yantu gongcheng xuebaoThermally induced deformation and fracture of bedding rocks are critical concerns in geotechnical engineering, including geothermal mining and nuclear waste storage, as these phenomena are strongly influenced by material anisotropy.

Dynamical breakdown of the Ising spin-glass order under a magnetic field
, 2005 The dynamical magnetic properties of an Ising spin glass Fe$_{0.55}$Mn$_{0.45}$TiO$_3$ are studied under various magnetic fields. Having determined the temperature and static field dependent relaxation time $\tau(T;H)$ from ac magnetization measurements ...

Condensates of Strongly-interacting Atoms and Dynamically Generated Dimers
, 2007 In a system of atoms with large positive scattering length, weakly-bound diatomic molecules (dimers) are generated dynamically by the strong interactions between the atoms.
