Accelerating imperfect fluid
Publication date: Available online 20 February 2020Source: Physics Letters AAuthor(s): Hristu CuletuAbstractAn inhomogeneous fluid in accelerated motion is investigated. When the velocity field v(x) is not constant, the geometry viewed by a static observer is curved, as if the observer were immersed in a gravitational field. A velocity-dependent semiclassical gravitational potential is introduced, which obeys an Yukawa-type equation, written in Cartesian coordinates. The timelike and null geodesic equations are investigated. One finds that the fluid has zero energy density corresponding to the perfect fluid part but nonzer...

Publication date: Available online 19 February 2020Source: Physics Letters AAuthor(s): Wang Chen, Xiaoying Zhou, Pu Liu, Xianbo Xiao, Guanghui ZhouAbstractRecently, the nonlinear optical processes study on monolayer MoS2 has revealed the existence of a trigonal warping in the band structure which distorts the Fermi surface from a circle at low energies to a triangle at higher energies. Here we theoretically demonstrate that the trigonal warping induce important modifications on the Berry curvature, orbital magnetic moment, and valley Hall conductance in monolayer MoS2.

Interface trap-induced negative differential resistance in nMOSFET with floating source
Publication date: Available online 19 February 2020Source: Physics Letters AAuthor(s): Haifeng Chen, Hui Nie, Lixin GuoAbstractInterface trap can act as the generation center in device to induce a very weak generation current. We observed the negative differential resistance NDR of this generation current ID in nMOSFET with the floating source. It originates from that the generation function of interface trap is enabled and then is shut down in turn as increasing the drain voltage. This change relies on the interaction among the interface trap energy-level and the electron's Fermi-levels of drain and source under the float...
