DESCRIPTION:When electrons are forced to interact strongly with each other
 \, some of the most exotic electronic phases and novel quasiparticles can 
 emerge. A key approach to force electrons to strongly interact with one an
 other is to confine them to energy bands with no momentum dispersion\, i.e
 . flat bands. Flat bands can be realized in two-dimensional materials in a
  high magnetic field or in newly discovered moiré materials in which quan
 tum interference can give rise to flat energy bands. The journey of explor
 ing old and new flat bands\, using high resolution quantum microscopy\,  h
 as taken us from confirming some of the earliest predictions for correlate
 d phases of matter (such as formation of Wigner crystal)\, to new approach
 es to probe novel quantum phases that host exotic quasiparticles that are 
 neither bosons or fermions. These quantum phases may play a key role in th
 e future of quantum computing by providing an approach to build topologica
 l qubits. I’ll describe how a combination of imaging electronic states o
 n the nanoscale and building structures from two-dimensional materials and
  their stacks may make building such qubits possible.
