Divergence and Curl of Magnetic Field

The magnetic field due to a volume current distribution given by the Biot–Savart Law can be expressed as follows:

Standing Waves in a Cavity

Standing Waves in a Cavity

A household microwave and lasers are examples of standing electromagnetic waves in a cavity. When two conducting metal plates are placed parallel at the nodal planes, it creates a cavity where standing waves are formed. The cavity between the two planes is analogous to a stretched string held at the points x = 0 and x = L. Here, the distance 'L' between the two planes must be an integer multiple of half of the wavelength. The wavelengths that satisfy this condition are given by:

Differential Form of Maxwell's Equations

Differential Form of Maxwell's Equations

James Clerk Maxwell (1831–1879) was one of the significant contributors to physics in the nineteenth century. He is probably best known for having combined existing knowledge of the laws of electricity and the laws of magnetism with his insights to form a complete overarching electromagnetic theory, represented by Maxwell's equations. The four basic laws of electricity and magnetism were discovered experimentally through the work of physicists such as Oersted, Coulomb, Gauss, and Faraday.

Gauss's Law: Planar Symmetry

Gauss's Law: Planar Symmetry

A planar symmetry of charge density is obtained when charges are uniformly spread over a large flat surface. In planar symmetry, all points in a plane parallel to the plane of charge are identical with respect to the charges. Suppose the plane of the charge distribution is the xy-plane, and the electric field at a space point P with coordinates (x, y, z) is to be determined. Since the charge density is the same at all (x, y) - coordinates in the z = 0 plane, by symmetry, the electric field at P...

Hückel's Rule Diagram of π MOs: Frost Circle

Hückel's Rule Diagram of π MOs: Frost Circle

The Frost circle or the inscribed polygon method is a graphical method for determining the relative energies of π molecular orbitals (MOs) for planar, fully conjugated, and monocyclic compounds. This method was first described by A. A. Frost and Boris Musulin in 1953.
A Frost circle is constructed by drawing a polygon whose number of edges is equal to the number of carbons of the given cyclic system, with one of the vertices pointing down. Then, a circle is drawn enclosing the polygon so that...

Boundary Conditions: Lossless Lines

Boundary Conditions: Lossless Lines

Consider a single-phase, two-wire, lossless transmission line terminated by an impedance at the receiving end and a source with Thevenin voltage and impedance at the sending end. The line, with length, has a surge impedance and wave velocity determined by the line's inductance and capacitance.
At the receiving end, the boundary condition states that the voltage equals the product of the receiving-end impedance and current. This relationship is expressed as a function of the incident and...

A dipole interaction in holographic systems can alter fermion behavior. Increasing interaction strength shifts spectral weight and can dynamically create a Mott gap in the density of states.

Area of Science:

Theoretical Physics
Condensed Matter Physics
Holographic Duality

Background:

Fermions in holographic systems often exhibit non-minimal couplings to gravity and gauge fields.
Understanding these interactions is key to exploring emergent phenomena in quantum field theory.

Purpose of the Study:

To investigate the impact of a specific non-minimal coupling, the Pauli (dipole) interaction, on fermion properties within holographic models.
To analyze how this interaction affects fermion correlators and the density of states.

Main Methods:

Theoretical analysis of fermion correlators in holographic systems.
Examination of the fermion spectral density under varying dipole interaction strengths.

Main Results:

The dipole interaction significantly modifies the fermion spectral density.
Spectral weight is transferred between energy bands as interaction strength increases.
A critical interaction strength leads to the emergence of a gap in the fermion density of states.

Conclusions:

The Pauli interaction can dynamically induce a Mott gap without spontaneous symmetry breaking.
This finding offers insights into the emergence of gaps in strongly correlated fermionic systems.
