Understanding the effects of trace metals on human health is as complex as it is fascinating. As mentioned earlier, the high concentrations may prove toxic, as also, depletion in the concentration of ...
The Hawking temperature for the Barriola-Vilenkin global monopole metric is shown to be TBV = ~(1− )2 8GMkB, where is the global monopole charge,M the mass of the black hole, kB is the Boltz...
The Ricci and energy-momentum tensors have the same algebraic sym-metries. In the Einstein equations they look “dual” to each other, in that interchang-ing them and inverting the gravitational couplin...
We introduce the quantum fractional Hadamard transform with continuous variables. It is found that the corresponding quantum fractional Hadamard operator can be decomposed into a single-mode fractiona...
We consider a micromaser model to study the influence of Dicke superradiance in the context of the one-atom maser. The model involves a microwave cavity into which twolevel Rydberg atoms are pumped ...
