WebbThe idea that leads us to the topology of gapless systems is extremely simple. It is: If we consider momentum as an external conserved parameter, we can study topological closings of the gap in momentum space. Let’s consider the simplest type of topological invariant, one we learned about at the very beginning of this course. Webb14 aug. 2024 · As the characteristic scale of products and production processes decreases, the plasticity phenomena observed start to deviate from those evidenced at the macroscale. The current research aims at investigating this gap using a lower-order gradient enhanced approach both using phenomenological continuum level as well as …
