Doping a semiconductor to create an unconventional metal
N. Manyala, J. F. DiTusa, G. Aeppli +1
Landau Fermi liquid theory, with its pivotal assertion that electrons in metals can be simply understood as independent particles with effective masses replacing the free electron…
A new algorithm for anisotropic solutions
M. Chaisi, S. D. Maharaj
We establish a new algorithm that generates a new solution to the Einstein field equations, with an anisotropic matter distribution, from a seed isotropic solution. The new solutio…
Phase formation and superconductivity of Fe-tube encapsulated and vacuum annealed MgB2
K. P. Singh, V. P. S. Awana, Md. Shahabuddin +7
We report optimization of the synthesis parameters viz. heating temperature (TH), and hold time (thold) for vacuum (10-5 torr) annealed and LN2 (liquid nitrogen) quenched MgB2 comp…
New anisotropic models from isotropic solutions
S. D. Maharaj, M. Chaisi
We establish an algorithm that produces a new solution to the Einstein field equations, with an anisotropic matter distribution, from a given seed isotropic solution. The new solut…
Compact anisotropic spheres with prescribed energy density
M. Chaisi, S. D. Maharaj
New exact interior solutions to the Einstein field equations for anisotropic spheres are found. We utilise a procedure that necessitates a choice for the energy density and the rad…
