Magnetic moment collapse induced axial alternative compressibility of Cr2TiAlC2 at 420 GPa from first principle
The electronic structure and thermodynamical properties of Cr2TiAlC2 are studied by first principles under pressure. The obtained results observed that the ferromagnetic order is the most stable ground state and the magnetic moment will collapse at about 50 GPa. As a result, the lattice a axis becomes stiffer above about 420 GPa, ultimately presenting the same axial compressibility trends with ...
متن کاملNegative viscosity from negative compressibility and axial flow shear stiffness in a straight magnetic field
J. C. Li and P. H. Diamond CMTFO and CASS, University of California, San Diego, California 92093, USA Abstract Negative compressibility ITG turbulence in a linear plasma device (CSDX) can induce a negative viscosity increment. However, even with this negative increment, we show that the total axial viscosity remains positive definite, i.e. no intrinsic axial flow can be generated by pure ITG tu...
متن کاملAxial coupling and Magnetic moment of D∗ meson
The axial coupling and the magnetic moment of D-meson or, more specifically, the couplings gD∗Dπ and gD∗Dγ , encode the non-perturbative QCD effects describing the decays D → Dπ and D → Dγ. We compute these quantities by means of lattice QCD with Nf = 2 dynamical quarks, by employing the Wilson (“clover”) action. On our finer lattice (a ≈ 0.065 fm) we obtain: gD∗Dπ+ = 20 ± 2, and gD∗0D0γ = 2.0±...
متن کاملCollapse of magnetic moment drives the Mott transition in MnO.
The metal-insulator transition in correlated electron systems, where electron states transform from itinerant to localized, has been one of the central themes of condensed-matter physics for more than half a century. The persistence of this question has been a consequence both of the intricacy of the fundamental issues and the growing recognition of the complexities that arise in real materials...
متن کامل420 Lentil Allergy: First Report from Venezuela
a interesting tool to help the diagnosis of non type I Allergy reactions, and there are many published studies that have been established that the decrease or even disappearance of specific IgG titers against foods are related to the improvement of the initial clinical manifestations on some patients, but further investigations need to be performed to clearly understand the different mechanisms...
