Major changes in the gameplay from Mass Effect are listed in the main Mass Effect 2 page, while the effects of importing a saved game from Mass Effect are listed in the Save File Transfer page. The research was published in National Science Review, and the study was led by Prof. This page contains a walkthrough for the main missions of Mass Effect 2. The hidden physics can be generalized to many degrees of freedom, including spin, orbital, and circular polarizations in the future. Moreover, the authors proposed more material candidates for the layer Hall effect, which will inspire more experimental explorations. The authors revealed three distinct features to enhance the layer Hall effect in PT-symmetric antiferromagnetic insulators. Therefore, they also proposed an alternative approach, the nonlocal measurement, to identify the layer Hall effect, without applying the electric field. They show that the existence of the layer Hall effect is irrelevant to the electric field, which is similar to the valley/spin Hall effect. The authors proposed a universal picture in terms of hidden Berry curvature for the layer Hall effect. In the layer Hall effect, electrons from the top and bottom layers are deflected in opposite directions and were measured by applying an out-of-plane electric field to break the PT symmetry, where P and T represent inversion symmetry and time-reversal symmetry, respectively. The first experiment on a new type of Hall effect, the layer Hall effect, had been reported by Xu's group at Harvard University. Credit: Science China PressĮvery time a new Hall effect is discovered, a wave of research is inspired. The green arrows denote the in-plane electric field Ey for the Hall measurement. The yellow arrows specify the antiferromagnetic configurations. (c)-(d) When a perpendicular electric field (the cyan arrow) is applied, the system shows layer-locked anomalous Hall effects tunable by the electric-field direction. In the layer Hall effect, electrons are spontaneously deflected to opposite sides at different layers (the red and blue arrowed curves) due to the layer-locked hidden Berry curvature.
