Recently, a type of Hall effect due to an unusual layer-locked Berry curvature called the layer (LHE) has been reported in even-layered two-dimensional antiferromagnetic (AFM) MnBi2Te4 [A. Gao et.al, Nature 595, 521 (2021)]. In this work, we report that quantization LHE, which call quantum anomalous (QALHE), can be realized MnBi2Te4. The QALHE originates from kicking Berry-curvature monopole ou...

A natural, non-supersymmetric solution to the hierarchy problem generically requires fermionic partners of the top quark with masses not much heavier than 500GeV. We study the pair production and detection at the LHC of the top partners with electric charge Qe = 5/3 (T5/3) and Qe = −1/3 (B), that are predicted in models where the Higgs is a pseudo-Goldstone boson. The exotic T5/3 fermion, in pa...

The motion of a Schwarzschild black hole with velocity v 0 ¼ 0 c through a constant magnetic field B 0 in vacuum induces a component of the electric field along the magnetic field, generating a nonzero second Poincaré electromagnetic invariant à F Á F Þ 0. This will produce (e.g., via radiative effects and vacuum breakdown) an electric charge density of the order of ind ¼ B 0 0 =ð2eR G Þ, where...

A fundamentally new understanding of the classical electromagnetic interaction of a point charge and a magnetic dipole moment through order v/c is suggested. This relativistic analysis connects together hidden momentum in magnets, Solem’s strange polarization of the classical hydrogen atom, and the Aharonov-Bohm phase shift. First we review the predictions following from the traditional particl...

The multiscale nature of cracking in ferroelectric ceramics is explored in relation to the crack growth enhancement and retardation behavior when the direction of applied electric ®eld is reversed with reference to that of poling. An a priori knowledge of the prevailing fracture behavior is invoked for the energy dissipated in exchange of the macroand micro-crack surface. To avoid the formalism...

In amorphous A170Si17Fe13, a fraction p+ 2. 0.50 of iron atoms have a positive electric field gradient (EFG), After crystallization, p+ increases strongly while the mean quadrupole splitting and isomer shift show almost no change. The results are interpreted with the help of EFG models. I INTRODUCTION Melt-spun aluminium-based amorphous alloys have been recently described in Al-transition metal...

We investigate the behavior of electric fields originating from adsorbates deposited on a cryogenic atom chip as it is cooled from room temperature to cryogenic temperature. Using Rydberg electromagnetically induced transparency, we measure the field strength versus distance from a 1 mm square of yttrium barium copper oxide (YBCO) patterned onto a yttria stabilized zirconia chip substrate. We f...

I correct hundred years old theory of charge distribution within an electrolytic solution surrounded by charged walls. Existing theory always implies excess amount of counter-ions (having polarity unlike walls) everywhere in the solution domain; so it cannot handle a solution that possesses excess ions of other type (co-ions) or is electrically neutral as a whole. Here, in the corrected distrib...

We report a beam deflection technique that exploits electric-field controlled deflection and total internal reflection at the interface between two anti-parallel domains realized in a single crystal lithium niobate wafer. The LiNbO3 z-cut sample was 500-μm-thick and was photolithographically patterned and poled by means of an applied electric field, in order to realize two adjacent regions of o...

Controlling spin current and magnetic exchange coupling by applying an electric field and achieving high spin injection efficiency at the same time in a nanostructure coupled to ferromagnetic electrodes have been the outstanding challenges in nanoscale spintronics. A relentless quest is going on to find new low-dimensional materials with tunable spin dependent properties to address these challe...
