We find Einstein’s notational equation of the electro-magnetic field equation and the electromagneticfield in Rindler space-time. Because, electromagnetic fields of the accelerated frame include in general relativity theory.

In the general relativity theory, we find the electro-magnetic wave function and equation in Rindlerspace-time. Specially, this article is that electromagnetic wave equation is corrected by the gauge fixingequation in Rindler space-time. We define the force in Rindler space-time We find Lorentz force(electromagnetic force) by electro-magnetic field transformations in Rindler space-time. In the inertial frame, Lorentz force is defined as 4-dimensional force. Hence, we had to obtain 4-dimensional force in Rindler space-time. We define energy-momentum in Rindler space-time.

In the special relativity theory, we study the gauge theory in the electro-magnetic field theory.Using that the Electro-magnetic potential is 4-vector, we treat the invariant potential. Electro-magnetic field theory’s the gauge theory is expanded

AbstractQuantum spin liquids provide paradigmatic examples of highly entangled quantum states of matter. Frustration is the key mechanism to favor spin liquids over more conventional magnetically ordered states. Here we propose to engineer frustration by exploiting the coupling of quantum magnets to the quantized light of an optical cavity. The interplay between the quantum fluctuations of the electro-magnetic field and the strongly correlated electrons results in a tunable long-range interaction between localized spins. This cavity-induced frustration robustly stabilizes spin liquid states, which occupy an extensive region in the phase diagram spanned by the range and strength of the tailored interaction. This occurs even in originally unfrustrated systems, as we showcase for the Heisenberg model on the square lattice.

Responses of plants to environmental signals have been studied for a long time. These responses are exhibited in the form of morphological and physiological adaptations, and relaying the signal to environment (including other plants) through volatile organic compounds and extrinsic chemicals as well as proteins. However these signals do not correspond to the consciousness in the plants. Recent research in this field has produced evidence of non-physical signals e.g. sound and (electro) magnetic field. Plants produce such signals as well as perceive and respond to these signals. There are many novel techniques that have been used in last three-four decades to understand such signals, mostly acoustic signals. This review summarizes the old knowledge as well as recent developments in the area of generation, perception, integration and processing of acoustic signals by the plants as a response to the environment as well as to communicate among themselves. If understood fully, technological interventions and manipulations of these signals can add an extra tool for crop improvement.

The article presents the method of drying the adsorbent by an electro-magnetic field. Shown is the technology of the possession for the fast regeneration of naphtha and the adsorbent from the intake of the forced HF electromagnet field. During operation of the transformer, the oil absorbs atmospheric moisture and its dielectric strength decreases. To reduce the water content of the oil, it is pumped through a reservoir containing an adsorbent such as zeolite or silica gel. The adsorbent that has lost its sorption capacity can be restored by removing moisture by heating. The adsorbent can be processed by calcining it on metal sheets or heating it in sealed containers under reduced pressure using heating coils. The use of the first method leads to the destruction of the adsorbent during its transition from the adsorber and vice versa.

Quantum control of Bose-Einstein-Condensates (BEC) had been found for one and two dimension cases. Firstly in this paper, we want to control BEC at electro-magnetic field in three dimension optical lattice theoretically. The trapped particles in constructed lattices can be made and controlled by optical pulse, and known as molasses. It is evident that quantum control theory is worked for physical particles in BEC status. It is a survey with system control and quantum particle physics. Future work is to focus on collaborating with real laboratory.
