Uncomputability of phase diagrams [PDF]
Nature Communications, 2021 AbstractThe phase diagram of a material is of central importance in describing the properties and behaviour of a condensed matter system. In this work, we prove that the task of determining the phase diagram of a many-body Hamiltonian is in general uncomputable, by explicitly constructing a continuous one-parameter family of Hamiltonians H(φ), where $$\

Metallurgical and Materials Transactions A, 2014 Abstract With the use of today’s computer softwares, phase diagrams can readily be plotted with a wide choice of variables on the axes. Hillert defined a true phase diagram as a diagram where each point uniquely defines the stable phases. He also showed that not all choices of axis variables give true phase diagrams.

Phase diagram of hard tetrahedra [PDF]
The Journal of Chemical Physics, 2011 Advancements in the synthesis of faceted nanoparticles and colloids have spurred interest in the phase behavior of polyhedral shapes. Regular tetrahedra have attracted particular attention because they prefer local symmetries that are incompatible with periodicity. Two dense phases of regular tetrahedra have been reported recently.

Periodic‐phase‐diagram similarity method for weak signal detection
International Journal of Mechanical System Dynamics, 2021 The periodic‐phase‐diagram similarity method is proposed to identify the frequency of weak harmonic signals. The key technology is to find a set of optimal coefficients for Duffing system, which leads to the periodic motion under the influence of weak ...

Effective Kinetic Phase Diagrams [PDF]
The Journal of Physical Chemistry B, 2005 The composition of a solid solution that is growing at conditions well away from equilibrium is not prescribed by equilibrium thermodynamics, but is determined kinetically. It depends both on the surface kinetics and on the transport of mass and heat to and away from the solidification front. In previous work, we have formulated a model for the kinetic

Dissolution Phase Diagram in Radial Geometry
Frontiers in Physics, 2020 Fractures play an important role as flow paths in porous media. When an undersaturated reactive fluid is flowing in a fracture, the dissolution process will alter the flow paths locally.

Phase diagram of an extended parafermion chain
SciPost Physics Core, 2022 We study the phase diagram of an extended parafermion chain, which, in addition to terms coupling parafermions on neighbouring sites, also possesses terms involving four sites.
