Creating boundaries along a synthetic frequency dimension
Avik Dutt, Luqi Yuan, Ki Youl Yang +4
Synthetic dimensions have garnered widespread interest for implementing high dimensional classical and quantum dynamics on lower dimensional geometries. Synthetic frequency dimensi…
Nonequilibrium Casimir effects of nonreciprocal surface waves
Chinmay Khandekar, Siddharth Buddhiraju, Paul R. Wilkinson +4
We show that an isotropic dipolar particle in the vicinity of a substrate made of nonreciprocal plasmonic materials can experience a lateral Casimir force and torque when the parti…
Arbitrary linear transformations for photons in the frequency synthetic dimension
Siddharth Buddhiraju, Avik Dutt, Momchil Minkov +2
Arbitrary linear transformations are of crucial importance in a plethora of photonic applications spanning classical signal processing, communication systems, quantum information p…
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…

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…
Gate-tunable near-field heat transfer
Georgia T. Papadakis, Bo Zhao, Siddharth Buddhiraju +1
Active control over the flow of heat in the near-field holds promise for nanoscale thermal management, with applications in refrigeration, thermophotovoltaics, and thermal circuitr…
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…
Thermodynamic Limits of Energy Harvesting from Outgoing Thermal Radiation
Siddharth Buddhiraju, Parthiban Santhanam, Shanhui Fan
We derive the thermodynamic limits of harvesting power from the outgoing thermal radiation from the ambient to the cold outer space. The derivations are based on a duality relation…
Optimal Single Quantum Dot Heat-to-pure-spin-current Converters
