A Turaev surface approach to Khovanov homology

open access: yes, 2013
We introduce Khovanov homology for ribbon graphs and show that the Khovanov homology of a certain ribbon graph embedded on the Turaev surface of a link is isomorphic to the Khovanov homology of the link (after a grading shift). We also present a spanning

Switching strategy for isolated dual‐active‐bridge converter

open access: yesIET Power Electronics, 2017
The operating characteristics of a dual‐active‐bridge (DAB) converter are generally poor when using the single‐phase‐shift (SPS) control strategy while working with a light load or when the input voltage and the output voltage are not matched with the transformer ratio.

Complexity, action, and black holes [PDF]

open access: yes, 2016
Our earlier paper "Complexity Equals Action" conjectured that the quantum computational complexity of a holographic state is given by the classical action of a region in the bulk (the "Wheeler-DeWitt" patch).
