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 ...

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.

Charting the phase diagram of QCD3
Journal of High Energy Physics, 2019 We study the phase diagram of SU (N) gauge theory in three space-time dimensions with a Chern-Simons term at level k, coupled to two sets of fundamental fermions with masses m 1 and m 2, respectively.

Physical Review B, 2017 The temperature-pressure phase diagram of ferromagnetic superconductor UCoGe includes four phase transitions. They are between the paramagnetic and the ferromagnetic states with the subsequent transition in the superconducting ferromagnetic state and between the normal and the superconducting states after which has to occur the transition to the ...

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

Phase diagram of Bi2Sr2CaCu2O8+δ revisited
Nature Communications, 2018 The doping level of cuprate superconductors is usually difficult to determine. Here, Drozdov et al. report spectroscopic studies of in-situ modified Bi2Sr2CaCu2O8+δ , exploring not only the superconducting dome but also the previously inaccessible, non ...

Pressure–Temperature Phase Diagram of Multiferroic TbFe2.46Ga0.54(BO3)4
Magnetochemistry, 2022 The pressure–temperature phase diagram of the multiferroic TbFe2.46Ga0.54(BO3)4 was studied for hydrostatic pressures up to 7 GPa and simultaneously with temperatures up to 400 K by the Raman spectroscopy technique.

Modeling the Phase Diagram of Carbon [PDF]
Physical Review Letters, 2005 We determined the phase diagram involving diamond, graphite, and liquid carbon using a recently developed semiempirical potential. Using accurate free-energy calculations, we computed the solid-solid and solid-liquid phase boundaries for pressures and temperatures up to 400 GPa and 12 000 K, respectively.
