Quantum magnetic phase transition in square-octagon lattice was investigated by cellular dynamical mean field theory combining with continuous time quantum Monte Carlo algorithm. Based on the systematic calculation on the density of states, the double occupancy and the Fermi surface evolution of square-...

Therefore, in this paper, we established a multi-physics mathematical model of the internal flow of a laser melting pool under a steady magnetic field and simulated the dynamic evolution mechanism of the velocity field, flow field, surface tension, and free surface motion of the melt pool under...
Magnetic moment, also known as magnetic dipole moment, is the measure of the object's tendency to align with a magnetic field. The objects have a tendency to place themselves in such a way that the magnetic moment vector becomes parallel to the magnetic

The projected area of the loop on the x−y plane is πρ2 with a new radius, ρ. Thus, the mean square of the radius can be written as 〈ρ2〉=〈x2〉 + 〈y2〉, which is the mean square of the distance of the orbiting electron normal to the magnetic field (z-axis) through...
This is a useful quantity for materials exhibiting a square hysteresis loop ideal for amplifier-type applications. Magnetic materials are classified as soft or hard (permanent) depending on the value of coercivity Hc, which is the field strength required to reduce the flux density to zero after ...
