Exploring the source of free energy is of practical use for thermodynamical systems. In the classical regime, the free energy change is independent of magnetism, as the Lorentz force is conservative. In contrast, here we find that the free energy change can be amplified by adding a magnetic fi...
Particles are accelerated to very high, non-thermal energies during explosive energy-release phenomena in space, solar, and astrophysical plasma environments. While it has been established that magnetic reconnection plays an important role in the dynamics of Earth’s magnetosphere, it remains unclear ho...

their mutual interaction can be obtained from the change of the total energy. To extract the interaction parameters, we invoke a multiple scattering theory realized by the Korringa–Kohn–Rostoker (KKR) Green-function formalism. Explicit expressions for the rigorous derivation of the topological-chiral...
The electrostatic energy density is thus U(E) εE 2/2 D(E/2. (J/m 3) (5.19) The last form is the three-dimensional extension of the derivation. The magnetic field energy density can be calculated by considering the toroidal core circuit of Figure 5.11. Because the core is ...
The nuclear Zeeman term − mN· B0 is not included in the electronic energy in a quantum mechanical calculation, and therefore, the second derivative gives a shielding tensor component directly. No assumptions have been made about the level of theory in this derivation, which means that relativi...

We have not advanced any hypothesis about the microscopic structure of the JMN-1 singularity; however, since the energy density and tangential pressure are both positive [see the unnumbered equation following Eq. (1)], we assume that the JMN-1 singularity is made of ordinary matter. Data ...
energy resolution and unperturbed by elevated magnetic fields. The quantitative information provided by the thermodynamic oscillations enables high-precision derivation of the tight-binding hopping parameters and accurate reconstruction of the tunable band hybridization induced by the displacement field.
