Nonreciprocal metamaterial obeying time-reversal symmetry
Siddharth Buddhiraju, Alex Song, Georgia T. Papadakis +1
We introduce a class of non-Hermitian systems that break electromagnetic reciprocity while preserving time-reversal symmetry, and describe its novel polarization dynamics. We show…
Nonreciprocal radiative heat transfer between two planar bodies
Lingling Fan, Yu Guo, Georgia T. Papadakis +5
We develop an analytical framework for nonreciprocal radiative heat transfer in two-body planar systems. Based on our formalism, we identify effects that are uniquely nonreciprocal…
Broadening near-field emission for performance enhancement in thermophotovoltaics
Georgia T. Papadakis, Siddharth Buddhiraju, Zhexin Zhao +2
The conventional notion for achieving high efficiency in thermophotovoltaics (TPVs) is to use a monochromatic emission at a photon energy corresponding to the band gap of the cell.…
Photonic refrigeration from time-modulated thermal emission
Siddharth Buddhiraju, Wei Li, Shanhui Fan
Active photonic cooling is of significant importance to realize robust, compact, vibration-free, all-solid-state refrigeration. Currently proposed photonic cooling approaches are b…
Overcoming the absorption limit in high-harmonic generation from crystals
Hanzhe Liu, Giulio Vampa, Jingyuan Linda Zhang +6
Since the new millennium coherent extreme ultra-violet and soft x-ray radiation has revolutionized the understanding of dynamical physical, chemical and biological systems at the e…
Absence of unidirectionally propagating surface plasmon-polaritons in nonreciprocal plasmonics
Siddharth Buddhiraju, Yu Shi, Alex Song +5
In the presence of an external magnetic field, the surface plasmon polariton that exists at the metal-dielectric interface is believed to support a unidirectional frequency range n…
