Spin polarization and dichroism effects induced by an electric field
نویسندگان
چکیده
We show that electric field can induce spin polarization and dichroism effects in angle resolved photoemission spectroscopy ARPES in spin orbit coupling systems. The physical origin behind the effects essentially is the same as the intrinsic spin Hall effect induced by the electric field. Since the ARPES experiments have both energy and momentum resolutions, the origin of the intrinsic spin Hall effect can be directly verified by the ARPES experiments for individual band even if there is no net spin current.

Static-electric-field-induced polarization effects in harmonic generation
Two static-electric-field-induced effects on harmonic generation are demonstrated analytically and numerically: elliptic dichroism (in which the harmonic yield is different for right and left elliptically polarized laser fields) and elliptical polarization of harmonics produced by linearly polarized driving laser fields. Both effects stem from interference of real and imaginary parts of the non...
متن کاملVacuum Birefringence Caused by Arbitrary Spin Particles
The propagation of a linearly polarized laser beam in the external transverse magnetic field is studied. We take into consideration the vacuum polarization by arbitrary spin particles. With the help of the effective Lagrangian, Stokes parameters and induced ellipticity are evaluated. It is shown that ellipticity measured in the PVLAS experiment can be caused by charged spin-3/2 particles posses...
متن کاملElectric-Field-Induced Triplet to Singlet Transition in Size-2 Trigonal Zigzag Graphene Nanoflake
Using Hartree-Fock Su-Sheriffer-Heeger (HF-SSH) model, we have studied the dependence of the energies of the ground (magnetic triplet state) and the first exited (nonmagnetic singlet state) states of the size-2 trigonal zigzag graphene nanoflake (size-2 NF) on the intensity of an external in plane static electric field at zero temperature. We identify a transition from the magnetic triplet stat...
متن کاملPhenomenon of the Time-reversal-violating Photon Polarization Plane Rotation by a Gas Placed to an Electric Field
1. Violation of time reversal symmetry has been observed only in K0-decay many years ago [1], and remains one of the great unsolved problems in elementary particle physics. Since the discovery of the CP-violation in decay of K0-mesons, a few attempts have been undertaken to observe this phenomenon experimentally in different processes. However, that experiments have not been successful. At the ...
متن کاملSlow modes of polarization in purple membranes
The polarization of bacteriorhodopsin discs has been characterized by measurements of the electric dichroism induced by sinusoidal electric field pulses in the frequency range from 0.2 to 100 kHz with field strengths up to 40 kV m . Analysis of the stationary dichroism by a disk model with a saturating induced dipole moment in the direction of the plane shows saturation of the induced dipole at...
