High-rectification near-field radiative thermal diode using Weyl semimetals
Yang Hu, Haotuo Liu, Bing Yang +4
Thermal diodes, which allow heat transfer in a preferential direction while being blocked in a reverse direction, have numerous applications in thermal management, information proc…
Negative differential thermal conductance between Weyl semimetals nanoparticles through vacuum
Yasong Sun, Yang Hu, Kezhang Shi +3
In this work, the near-field radiative heat transfer (NFRHT) between two Weyl semimetal (WSM) nanoparticles (NPs) is investigated. The numerical results show that negative differen…
Coupling between hyperbolic phonon polaritons excited in two ultrathin hBN sheets
Xiaohu Wu, Chengshuai Su, Kezhang Shi +2
In this work, the hyperbolic phonon polaritons (HPPs) in ultrathin hBN sheets are numerically studied. The dispersion relation and distribution of electric field are calculated to…
Rotation-induced significant modulation of near-field radiative heat transfer between hyperbolic nanoparticles
Yang Hu, Yasong Sun, Zhiheng Zheng +3
Modulation of near-field radiative heat transfer (NFRHT) with rotated anisotropic hBN and MoO3 nanoparticles (NPs) are investigated. The spectral heat power, total heat power and e…
Corrected Proximity-Force Approximation for Lateral Casimir Forces
F. Bao, K. Shi
The widely-adopted proximity-force approximation (PFA) to estimate normal Casimir forces is known to be asymptotically exact at vanishing separations. In this letter, we propose a…
Inhomogeneity-Induced Casimir Transport of Nanoparticles
F. Bao, K. Shi, G. Cao +2
This letter proposes a scheme for transporting nanoparticles immersed in a fluid, relying on quantum vacuum fluctuations. The mechanism lies in the inhomogeneity-induced lateral Ca…
Quantum propulsion and trapping of nano-objects by inhomogeneity-induced lateral Casimir forces
F. Bao, K. Shi, S. He
Lateral Casimir force near a laterally-inhomogeneous plate is first revealed by both rigorous simulations and proximity approximations. The inhomogeneity-induced lateral Casimir fo…
