Abstract :

Feynman’s original idea of using one quantum system that can be controlled and

manipulated at will to simulate the behaviour of another more complex one has

flourished during the last decades in the field of cold atoms. More recently,

this concept started to be developed in nano photonics and in condensed matter.

In this talk, I will discuss a few recent experiments, in which 2D electron lattices

were engineered on the nanoscale. The first is the Lieb lattice [1], and the second

is a Sierpinski gasket [2]. The realisation of fractal lattices opens up the path to

electronics in fractional dimensions.

At the end, I will discuss some ongoing projects on orbitronics and topological states.
