Dissipative Channels Determine Open Electromagnetic Quantization
Hyunwoo Choi, Junwoo Gim, Thomas E. Roth +2
We formulate a quantization scheme for open electromagnetic systems with arbitrary passive boundary conditions. Rather than specifying reservoirs phenomenologically, the method ide…
Computational framework for non-Markovian multi-emitter dynamics beyond the single-excitation limit
Hyunwoo Choi, Weng Cho Chew, Dong-Yeop Na
While non-Markovian dynamics have been extensively studied in the single-excitation limit to predict non-trivial phenomena, this regime remains an idealization. Moving beyond it is…
Numerical Evaluation of Angle-Dependent IR-Transparent Radiative Cooling Performance for Asymmetric Periodic Structures
Junwoo Gim, Jun Heo, Weng Cho Chew +1
Infrared (IR)-transparent passive radiative cooling (PRC) enables non-contact thermal management by regulating radiative heat exchange without direct attachment to the cooling obje…
Numerical Framework for Multimode Jaynes- and Tavis-Cummings Models Incorporating the Modified Langevin Noise Formalism: Non-Markovian Analysis of Atom-Field Interactions in Dissipative Electromagnetic Environments
Hyunwoo Choi, Weng Cho Chew, Dong-Yeop Na
We present a novel numerical framework that integrates the modified Langevin noise formalism into the multimode Jaynes- and Tavis-Cummings models, enabling a first-principles, non-…
