Invited Speaker / Conférencier(ère) invité(e)

Moiré materials are defined by a delicate interplay of symmetry and nanoscale registry, yet the most important structural tuning parameters are often frozen once a heterostructure is assembled. I will present a "scanning van der Waals microscope" that creates a pristine nanoscale 2D-2D junction on a probe and rotates the interface in situ, enabling continuous twist control while measuring...

Invited Speaker / Conférencier(ère) invité(e)

Monolayer transition metal dichalcogenides have emerged as key materials for investigating the interplay between spin and valley degrees of freedom. The strong spin-orbit interaction and the lack of inversion symmetry in these materials result in a spin-valley locking, in which carriers in the K and K’ valleys possess opposite spin polarization. This effect is particularly pronounced for holes...

We demonstrate that chains of bilayer graphene quantum dots (BLGQDs) can realize topological quantum matter by effectively simulating spin-1 chains that host the Haldane phase. Using an atomistic tight-binding model combined with exact diagonalization, we show that two electrons per quantum dot form a robust spin-1 ground state across interaction regimes. For coupled quantum dots, the...
