Magneto-Optical Kerr Effect Driven by Spin Accumulation on Cu, Au, and Pt

open access: yesApplied Sciences, 2018
The magneto-optical Kerr effect (MOKE) has recently been achieved on non-ferromagnetic metals by injecting spin currents. To use the magneto-optical Kerr effect as a quantitative tool, it is crucial to study the relationship between the Kerr rotation ...

The ultrafast Kerr effect in anisotropic and dispersive media [PDF]

open access: yesThe Journal of Chemical Physics, 2021
The ultrafast optical Kerr effect (OKE) is widely used to investigate the structural dynamics and interactions of liquids, solutions, and solids by observing their intrinsic nonlinear temporal responses through nearly collinear four-wave mixing. Non-degenerate mixing schemes allow for background free detection and can provide information on the ...

Saturation of the All-Optical Kerr Effect

open access: yesPhysical Review Letters, 2011
Saturation of the intensity dependence of the refractive index is directly computed from ionization rates via a Kramers-Kronig transform. The linear intensity dependence and its dispersion are found in excellent agreement with complete quantum mechanical orbital computations.

Blue phase liquid crystal: strategies for phase stabilization and device development

open access: yesScience and Technology of Advanced Materials, 2015
The blue phase liquid crystal (BPLC) is a highly ordered liquid crystal (LC) phase found very close to the LC–isotropic transition. The BPLC has demonstrated potential in next-generation display and photonic technology due to its exceptional properties ...

Casimir effect in the Kerr spacetime with quintessence [PDF]

open access: yesModern Physics Letters A, 2016
We calculate the Casimir energy of a massless scalar field in a cavity formed by nearby parallel plates orbiting a rotating spherical body surrounded by quintessence, investigating the influence of the gravitational field on that energy, at zero temperature. This influence includes the effects due to the spacetime dragging caused by the source rotation
