Breaking Rayleigh's law with spatially correlated disorder to control phonon transport
Simon Thébaud, Lucas Lindsay, Tom Berlijn
Controlling thermal transport in insulators and semiconductors is crucial for many technological fields such as thermoelectrics and thermal insulation, for which a low thermal cond…
Magnon Orbital Angular Momentum of Ferromagnetic Honeycomb and Zig-Zag Lattices
R. S. Fishman, T. Berlijn, J. Villanova +1
By expanding the gauge for magnon band in harmonics of momentum , we demonstrate that the only observable component of the magnon orbital angular momen…
Atomic dynamics in fluids: Normal mode analysis revisited
Jaeyun Moon, Lucas Lindsay, Takeshi Egami
Developing microscopic understanding of the thermal properties of liquids is challenging due to their strong dynamic disorder, which prevents characterization of the atomic degrees…
Primitive to conventional geometry projection for efficient phonon transport calculations
Xun Li, Simon Thebaud, Lucas Lindsay
The primitive Wigner-Seitz cell and corresponding first Brillouin zone (FBZ) are typically used in calculations of lattice vibrational and transport properties as they contain the…
Differential Multi-probe Thermal Transport Measurements of Multi-walled Carbon Nanotubes grown by Chemical Vapor Deposition
Qianru Jia, Yuanyuan Zhou, Xun Li +2
Carbon nanotubes (CNTs) are quasi-1D nanostructures that display both high thermal conductivity and intriguing low-dimensional phonon transport phenomena. In comparison to the adva…
