Non-trivial point-gap topology and non-Hermitian skin effect in photonic crystals
Janet Zhong, Kai Wang, Yubin Park +4
We show that two-dimensional non-Hermitian photonic crystals made of lossy material can exhibit non-trivial point gap topology in terms of topological winding in its complex freque…

Violating Kirchhoff's Law of Thermal Radiation in Semitransparent Structures
Yubin Park, Viktar S. Asadchy, Bo Zhao +3
Kirchhoff's law of thermal radiation imposes a constraint on photon-based energy harvesting processes since part of the incident energy flux is inevitably emitted back to the sourc…
