Two dimensional materials like transition metal dichalcogenides are known to exhibit fascinating effects. I will talk about two types of such interesting phenomena. The first part of the talk deals with two acoustic transport phenomena due to a deformation potential resulting from the exposure of the system to Rayleigh surface acoustic waves-namely the valley acoustoelectric effect and valley spin acoustic resonance. The second part of the talk will be about the effect of presence of superconducting fluctuations in 2D materials. Specifically, the modifications of these fluctuations on the coherent photogalvanic effect and the magnetoplasmon resonance will be discussed.
