Time-delayed opinion dynamics with leader-follower interactions: consensus, stability, and mean-field limits
We study a time-delayed variant of the Hegselmann-Krause opinion formation model featuring a small group of leaders and a large group of non-leaders. In this model, leaders influence all agents but only interact among themselves. At the same time, non-leaders update their opinions via interactions with their peers and the leaders, with time delays accounting for communication and decision-making lags. We prove the exponential convergence to consensus of the particle system, without imposing sma…

High-magnitude, spatially variable, and sustained strain engineering of 2D semiconductors
Crystalline two-dimensional (2D) semiconductors often combine high elasticity and in-plane strength, making them ideal for strain-induced tuning of electronic characteristics, akin to strategies used in silicon electronics. However, current techniques fall short in achieving high-magnitude (>1%), spatially resolved, and stable strain in these materials. Here, we apply biaxial tensile strain up to 2.2%, with +/-0.12% resolution over micrometre-scale regions in monolayer MoS2 via conformal transf…
