Two--dimensional lattice Gross--Neveu model with Wilson twisted mass fermions [PDF]

, 2005
We study the two-dimensional lattice Gross--Neveu model with Wilson twisted mass fermions in order to explore the phase structure in this setup. In particular, we investigate the behaviour of the phase transitions found earlier with standard Wilson ...

Suppressing σ phase formation by rapid solidification to prevent embrittlement in a low-cost aged medium-entropy alloy

Journal of Materials Research and Technology, 2023
Developing cost-effective high- and medium-entropy alloys (HEAs/MEAs) is essential to promote their broad industrial applications. A newly developed low-cost Fe45Cr25Ni10Mn15Al4C1 (at.%) MEA shows excellent compressive strength and ductility, but it is ...

Permutation-Symmetric Multicritical Points in Random Antiferromagnetic Spin Chains [PDF]

, 2002
The low-energy properties of a system at a critical point may have additional symmetries not present in the microscopic Hamiltonian. This letter presents the theory of a class of multicritical points that provide an interesting example of this in the ...

First principle energies of binary and ternary phases of the Fe–Nb–Ni–Cr system [PDF]

, 2011
We present first principles enthalpies of formation and lattice parameters of iron, nickel, chromium and niobium alloys. Some of these results have been partially used in a recent assessment of the Fe–Ni–Cr–Nb quaternary phase diagram.
