Brownian motion in superfluid He
Xiao Li, Ran Cheng, Tongcang Li +1
We propose to study the Brownian motion of a classical microsphere submerged in superfluid He using the recent laser technology as a direct investigation of the thermal fluctua…
Electronic Highways in Bilayer Graphene
Zhenhua Qiao, Jeil Jung, Qian Niu +1
Bilayer graphene with an interlayer potential difference has an energy gap and, when the potential difference varies spatially, topologically protected one-dimensional states local…
Anomalous Magnetic Susceptibility and Hall Effect from Valley Degrees of Freedom
Tianyi Cai, Wang Yao, Shengyuan A. Yang +2
We study the magnetic and transport properties of epitaxial graphene films in this letter. We predict enhanced signal of magnetic susceptibility and relate it to the intrinsic vall…
Quantum Size Effect and Electronic Stability of Freestanding Metal Atom Wires
Haiping Lan, Ping Cui, Jun-Hyung Cho +3
Using DFT calculations, we present a thorough study of the quantum size effects on the stability of freestanding metal atom wires. Our systems include Na, Ag, Au, In, Ga and Pb ato…
