This study discusses the implications of principle locality for interference in quantum field theory. As an example, it considers interaction two charges via a mediating and resulting pattern Lorenz gauge. Using Heisenberg picture, is proposed that detecting relative phases or entanglement between experiment equivalent to accessing empirically gauge degrees freedom associated with so-called gho...

We propose and demonstrate a novel implementation of spectral-shearing interferometry (SSI) for reconstructing the electric field of ultrashort pulses by utilizing asymmetric group velocity matching in a long nonlinear crystal. The proposed configuration eliminates the requirement for a linearly chirped auxiliary pulse that is in common in all existing SSI methods, relying on nonlinear conversi...

chickpea (cicer arietinum) is the third most important pulse crop in the world, grown widely across asia and the middle east. weed is one of the main limiting factors in chickpea (cicer arietinum) production. several characteristics of chickpea (cicer arietinum), such as slow plant emergence, short plant height, and chickpea morphology allow weeds to compete effectively. to investigate the effe...

Abstract—The interference behaviors of a vector optical field with both radially and azimuthally variant states of polarization (SoP) through the Young’s two-slits are theoretically studied. The optical field distribution with periodic stripes in the far field results from the interference of the vector optical field through the Young’s two-slits with different initial SoP distributions. It is ...

BACKGROUND Little is known about the magnetic field strength of portable headphones and their potential to cause magnetic interference with implanted pacemakers (PMs) and implantable cardioverter-defibrillators (ICDs). OBJECTIVE The purpose of this study was to evaluate the magnetic field strength of portable headphones and to determine if they can cause clinically relevant magnetic interfere...

In adiabatic rapid passage, the Bloch vector of a qubit is inverted by slowly inverting an external field to which it is coupled, and along which it is initially aligned. In non-adiabatic twisted rapid passage, the external field is allowed to twist around its initial direction with azimuthal angle φ(t) at the same time that it is non-adiabatically inverted. For polynomial twist, φ(t) ∼ Bt. We ...

The weak gravitational field expansion method to account for the gravitationally induced neutrino oscillation effect is critically examined, then it is shown that the splitting of the neutrino phase into a “kinematic” and a “gravitational” phase is not always possible because the relativistic factor modifies the particle interference phase splitting condition in a gravitational field. key words...
