Extraordinary momentum and spin in evanescent waves

Konstantin Y. Bliokh, +2 more
- 06 Mar 2014 - 
TL;DR: It is demonstrated that the transverse momentum and spin push and twist a probe Mie particle in an evanescent field allows the observation of 'impossible' properties of light and of a fundamental field-theory quantity, which was previously considered as 'virtual'.
Journal ArticleDOI

Dual electromagnetism: Helicity, spin, momentum, and angular momentum

Konstantin Y. Bliokh, +2 more
- 01 Mar 2013 - 
TL;DR: The dual symmetry between electric and magnetic fields is an important intrinsic property of Maxwell equations in free space as mentioned in this paper, which underlies the conservation of optical helicity and is closely related to the separation of spin and orbital degrees of freedom of light.
Journal ArticleDOI

Internal flows and energy circulation in light beams

Aleksandr Bekshaev, +2 more
- 24 Mar 2011 - 
TL;DR: In this article, a general description of the internal flows in the coordinate and momentum (angular spectrum) representations for both non-paraxial and paraxial fields is given, which enables one to determine local densities and integral values of the spin and orbital angular momenta of the field.
Journal ArticleDOI

Optical Momentum, Spin, and Angular Momentum in Dispersive Media

Konstantin Y. Bliokh, +5 more
- 18 Aug 2017 - 
TL;DR: It is shown that the kinetic Abraham momentum describes the energy flux and group velocity of the wave in the medium and novel canonical Minkowski-type momentum, spin, and orbital angular momentum densities of the field are introduced.
Journal ArticleDOI

Direct measurements of the extraordinary optical momentum and transverse spin-dependent force using a nano-cantilever

Massimo Antognozzi, +10 more
- 01 Aug 2016 - 
TL;DR: In this paper, a femtonewton-resolution nano-cantilever immersed in an evanescent optical field above the total internal reflecting glass surface was used to measure the optical momentum and force.
