Intermittency enhancement in quantum turbulence
Emil Varga, Jian Gao, Wei Guo +1
Intermittency is a hallmark of turbulence, which exists not only in turbulent flows of classical viscous fluids but also in flows of quantum fluids such as superfluid He. Despi…
An exploration of thermal counterflow in He II using particle tracking velocimetry
Brian Mastracci, Wei Guo
Visualization of thermal counterflow in He II using PIV (particle image velocimetry) and PTV (particle tracking velocimetry) is difficult because tracer particle motion can be infl…
Electrically Tunable and Reconfigurable Topological Edge State Lasers
Ruizhe Yao, Hang Li, Bowen Zheng +5
We report an actively tunable topological edge mode laser in a one-dimensional Su-Schrieffer-Heeger (SSH) laser chain, where the SSH chain is realized in an electrically-injected F…
A high order semi-Lagrangian discontinuous Galerkin method for the two-dimensional incompressible Euler equations and the guiding center Vlasov model without operator splitting
Xiaofeng Cai, Wei Guo, Jingmei Qiu
In this paper, we generalize a high order semi-Lagrangian (SL) discontinuous Galerkin (DG) method for multi-dimensional linear transport equations without operator splitting develo…
A Kernel Based High Order "Explicit" Unconditionally Stable Scheme for Time Dependent Hamilton-Jacobi Equations
Andrew Christlieb, Wei Guo, Yan Jiang
In this paper, a class of high order numerical schemes is proposed for solving Hamilton-Jacobi (H-J) equations. This work is regarded as an extension of our previous work for nonli…
