Transition metal dichalcogenide heterostructures have been extensively studied as a platform for investigating exciton physics. While heterobilayers such WSe_{2}/MoSe_{2} received significant attention, there has comparatively less research on heterotrilayers, which may offer new excitonic species and phases, well unique physical properties. In this Letter, we present theoretical experimental investigations the emission properties of quadrupolar excitons (QXs), newly predicted type exciton,...
Nonlinear photogalvanic effects in two-dimensional materials, particularly the nonlinear circular photocurrents (NCPs) that belong to helicity-dependent spin photocurrents, have sparked enormous research interest. Although notable progress has been witnessed, underling origin of NCPs remains elusive. Here, we present systematic photocurrent characteristics, symmetry analysis and theoretical calculations uncover physical MoS_{2}, a prototypical 2D semiconductor. Our results show NCP responses...
We have recently developed a series of accurately calibrated nuclear energy density functionals, fitted to essentially all atomic masses with model root mean square deviation now reduced 0.5 MeV for our functional BSk27*.At the same time, these functionals were adjusted realistic equations state neutron matter and constrained reproduce various properties matter.Using BSk27 * , we calculated internal constitution equation crust non-accreting stars.
