Transient heat transfer of superfluid He in nonhomogeneous geometries -- Part I: Second sound, rarefaction, and thermal layer
Shiran Bao, Wei Guo
Transient heat transfer in superfluid He (He II) is a complex process that involves the interplay of the unique counterflow heat-transfer mode, the emission of second-sound wav…
Superdiffusion of quantized vortices uncovering scaling behavior of quantum turbulence
Yuan Tang, Shiran Bao, Wei Guo
Generic scaling laws, such as the Kolmogorov's 5/3-law, are milestone achievements of turbulence research in classical fluids. For quantum fluids such as atomic Bose-Einstein conde…
Charge density wave and weak Kondo effect in a Dirac semimetal CeSbTe
Peng Li, Baijiang Lv, Yuan Fang +10
Using angle-resolved photoemission spectroscopy (ARPES) and low-energy electron diffraction (LEED), together with density-functional theory (DFT) calculation, we report the formati…
Spatial transient behavior in waveguides with lossy impedance boundary conditions
Wei Guo, Juan Liu, Wenping Bi +3
Attenuation in acoustic waveguides with lossy impedance boundary conditions are associated with non-Hermitian and non-normal operators. This subject has been extensively studied in…
New method for fitting the low-energy constants in chiral perturbation theory
Qin-He Yang, Wei Guo, Feng-Jun Ge +3
A new set of the next-to-leading order (NLO) and the next-to-next-to-leading order (NNLO) low-energy constants and in chiral perturbation theory is obtained. These…
Fully Coupled Two-Fluid Dynamics in Superfluid He: Anomalous Anisotropic Velocity Fluctuations in Counterflow
Satoshi Yui, Hiromichi Kobayashi, Makoto Tsubota +1
We investigate the thermal counterflow of the superfluid He by numerically simulating three-dimensional fully coupled dynamics of the two fluids, namely quantized vortices and…
