Optomechanical Self-Stability of Freestanding Photonic Metasurfaces
Avinash Kumar, Daniel Kindem, Ognjen Ilic
We develop an analytical framework for self-stabilizing optical manipulation of freestanding metasurfaces in three dimensions. Our framework reveals that the challenging problem of…

The metastable Mpemba effect corresponds to a non-monotonic temperature dependence of extractable work
Raphaël Chétrite, Avinash Kumar, John Bechhoefer
The Mpemba effect refers to systems whose thermal relaxation time is a non-monotonic function of the initial temperature. Thus, a system that is initially hot cools to a bath tempe…
