Analytical Floquet Quantum Statistics from Nonequilibrium Green's Functions
Yuhua Ren, Gaomin Tang, Hui Pan +1
We derive an analytical expression for the steady-state quantum statistics of periodically driven quantum systems coupled to a bath using the nonequilibrium Green's function (NEGF)…
The infinitesimal environmental dust as a photonic bath at infinity
Gaomin Tang, Yuhua Ren, Jian-Sheng Wang
In far-field thermal radiation, electromagnetic waves emitted by an object propagate to infinity, requiring the far region to be modeled as an effective thermal bath. This bath was…
Analytical formulas for far-field radiated energy and angular momentum of metallic thin films
Hankun Zhang, Yuhua Ren, Ho-Yuan Huang +1
We investigate far-field radiation of energy, linear momentum, and angular momentum from two-dimensional electron systems, focusing on metallic thin films described by the Drude co…
Clarification of Floquet--Enhanced Thermal Emission Through the Nonequilibrium Green's Function Formalism
Yuhua Ren, Hui Pan, Jian-Sheng Wang
Floquet engineering offers a powerful route to enhance emission in time-modulated media. Here, we investigate the influence of time-modulated permittivity in silicon carbide on its…
Anomalous Scaling Laws of Dispersion Interactions in Anisotropic Nanostructures
Hui Pan, Yuhua Ren, Jian-Sheng Wang
The van der Waals (vdW) dispersion interaction between two finite neutral objects typically follows the standard nonretarded law. Here, we reveal an anomalous sc…
Asymmetry-induced radiative heat transfer in Floquet systems
Hui Pan, Yuhua Ren, Gaomin Tang +1
Time modulation opens new avenues for light, heat control, and energy harvesting, yet the impact of nonequilibrium dynamics of microscopic particles remains largely unexplored. We…
Quantifying the magnetic interactions governing chiral spin textures using deep neural networks
Jian Feng Kong, Yuhua Ren, M. S. Nicholas Tey +4
The interplay of magnetic interactions in chiral multilayer films gives rise to nanoscale topological spin textures, which form attractive elements for next-generation computing. Q…
