We employ cluster extension of dynamical mean-field theory (CDMFT) to systematically investigate the impact of double counting corrections on the correlated electronic structure of La3Ni2O7 under ambient pressure. By adjusting double-counting parameters, while maintaining a fixed Fermi surface, we observe a pronounced orbital-selective density of states change: the \(d_{z^2}\) orbital undergoes significant variation near the Fermi level with increasing \(E_{dc}^z\), while the \(d_{x^2-

We predict the existence of two tri-critical quantum Lifshitz points in recently discovered d-wave altermagnetic metals subjected to an external magnetic field. These points connect a spatially modulated Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) phase, a uniform polarized Bardeen–Cooper–Schrieffer (BCS) superconducting phase, and the normal metallic phase in a nontrivial manner. Depending on whether the FFLO state is primarily induced by the magnetic field or by d-wave altermagnetism, we

We review field-theoretic studies of charge transport in hot relativistic plasmas under strong magnetic fields and extend the analysis to thermal conductivity. The calculations rely on accurately determining the fermion damping rate. Using the Landau-level representation, these damping rates are computed exactly at leading order and incorporated into the Kubo formula to obtain the thermal and electrical conductivity tensors. Our analysis reveals that the mechanisms underlying longitudi

A proton beam is produced at a velocity of the order of 109cm/s to interact with an uncharged hydrogen-boron medium such as H3B. The generated charged particles are confined by electromagnetic fields. This is the basic concept of the new non-thermal fusion reactor. An external electric field is applied to prevent the energy loss of the proton particles by friction, due to their interaction with the electrons of the medium, to keep the proton-boron fusion at a maximum cross-section.

Indirect-drive double-shell implosions have been performed at 100 kJ laser facility in China. The system of differential equations for the unablated mass, the average implosion velocity, and the ablation front radius of an outer shell within an indirect-drive double-shell capsule during acceleraction and deceleraction phases has been proposed from conservation principles of hydrodynamics. In addition, corrected rocket model for the inner shell has been built; the radius and velocity of

Multiferroic materials, particularly rare-earth orthochromates (RECrO\(_3\)), have garnered significant interest due to their unique magnetic and electric-polar properties, making them promising candidates for multifunctional devices. Although extensive research has been conducted on their antiferromagnetic (AFM) transition temperature (N\(\acute{\mathrm{e}}\)el temperature, \(T_\mathrm{N}\)), ferroelectricity, and piezoelectricity, the effects of doping and substitution of rare-earth
