We acknowledge PRACE for awarding us access to MareNostrum 4 at Barcelona Supercomputing Center (BSC), Spain (OptoSpin project id. 2020225411) Proximity effects between layered materials trigger a plethora of novel and exotic quantum transport phenomena. Besides, the capability to modulate the nature and strength of proximity effects by changing crystalline and interfacial symmetries offers a vast playground to optimize physical properties of relevance for innovative applications. In this work, we use large-scale first principles calculations to demonstrate that strain and twist-angle strongly vary the spin-orbit coupling in graphene/transition metal dichalcogenide heterobilayers. Such a change results in a modulation of the spin relaxation times by up to two orders of magnitude. Additionally, the relative strengths of valley-Zeeman and Rashba spin-orbit coupling can be tailored upon twisting, which can turn the system into an ideal Dirac-Rashba regime or generate transitions between topological states of matter. These results shed new light on the debated variability of spin-orbit coupling and clarify how lattice deformations can be used as a knob to control spin transport. Our outcomes also suggest complex spin transport in polycrystalline materials, due to the random variation of grain orientation, which could reflect in large spatial fluctuations of spin-orbit coupling fields

The International Organization for Migration (IOM) defines forced migration or forced displacement as migratory movement induced by several factors such as force, compulsion, or coercion. The United Nations High Commissioner for Refugees (UNHCR) reports that the number of displaced individuals almost doubled over the last decade, with around 40% of these individuals being compelled to cross borders. 1 These refugees or asylum seekers settle primarily in neighbouring countries, which are usually developing countries with limited resources and often precarious political situations. This report aims to better understand cross-border displacement by analysing the time sequence from events potentially inducing displacement to migration into the neighbouring country. This time sequence is of particular interest to many stakeholders, as better knowledge of the timing can help decision makers anticipate and plan possible actions to support host countries. For instance, it can help the planning of humanitarian corridors and resettlement pledges, as well as the support to international organisations providing shelter and assistance in refugees camps. Furthermore, timing on initial cross-border displacement can also inform about possible developments of mixed-migration along the migratory routes to Europe.
