Internal flows and energy circulation in light beams
Aleksandr Bekshaev, Konstantin Bliokh, Marat Soskin
We review optical phenomena associated with the internal energy redistribution which accompany propagation and transformations of monochromatic light fields in homogeneous media. T…

Orbital angular momentum of spatiotemporal vortices: a ray-mechanical analogy
Sophie Vo, Konstantin Y. Bliokh, Miguel A. Alonso
Spatiotemporal vortex pulses (STVPs) are wavepackets that carry transverse orbital angular momentum (OAM), whose proper quantification has been the subject of recent debate. In thi…

Momentum, spin, and orbital angular momentum of electromagnetic, acoustic, and water waves
Konstantin Y. Bliokh
Waves of various types carry momentum, which is associated with their propagation direction, i.e., the phase gradient. The circulation of the wave momentum density gives rise to or…
