The unique sensitivity of optical response to different types of symmetry breaking can be used to detect and identify spontaneously ordered many-body states in bilayer graphene. We predict a strong response at optical frequencies, sensitive to electronic phenomena at low energies, which arises because of nonzero interband matrix elements of the electric current operator. In particular, the pola...

A bstract The analytic continuation of the general signature (1, 3) Lorentzian Kerr-Taub-NUT black holes to (2, 2) Kleinian is studied. Their global structure characterized by a toric Penrose diagram resembling their counterparts. are found be self-dual when mass and NUT charge equal for any value Kerr rotation parameter . Remarkably, it shown that can eliminated large diffeomorphism; this resu...

The sensitivity of the magneto-optical Kerr response to electronic thermalization processes in ultrafast pump–probe experiments is studied by evaluating the complex conductivity tensor of Ni for non-equilibrium electron distributions. The electronic structure and optical matrix elements are calculated within density functional theory. To account for the electronic redistributions generated by t...

Recently we used the onion peeling method to reconstruct the axisymmetric electric field distribution of point/plane electrodes from Kerr electro-optic measurements. The method accurately reconstructed the electric field from numerically generated data. However in the presence of experimental noise the performance was less satisfactory. The measurements were especially noisy and unstable near t...

We present a comparative study on an experimental and theoretical optimization of magneto-optical Kerr setups based on photoelastic modulation and phase sensitive detector methodology. The first and second harmonics, I omega,2 omega, of the reflected light intensity are measured for a CoO/Co magnetic reference film. The magnetic field dependence of the optical off-diagonal Fresnel reflection co...

We calculate the frequency-dependent longitudinal and Hall conductivities Faraday Kerr rotation angles for a single sheet of anisotropic Dirac semimetal protected by nonsymmorphic symmetry in presence Zeeman term coupling to out-of-plane component spin. While causes plane polarization light, anisotropy appearance an elliptically polarized initially linearly beam. The two effects can be combined...

Gravitational Faraday Rotation (GFR) is a frame-dragging effect induced by rotating massive objects, which one of the important, yet studied characteristics lensed gravitational waves (GWs). In this work, we calculate GFR angle $\chi_g$ GWs in weak deflection limit, assuming it Kerr black hole (BH). We find that changes initial polarization state GW. Compared with Einstein angle, dominant term ...
