<font size="5"><b>Plethora of Many-Body Ground States in Magic
Angle Twisted Bilayer Graphene</b></font><br>
<br>
<div class="abstract tex"> Twist-angle engineering of 2D materials
has led to the recent discoveries of novel many-body ground
states in moiré systems such as correlated insulators,
unconventional superconductivity, strange metals, orbital
magnetism and topologically nontrivial phases. These systems are
clean and tuneable, where all phases can coexist in a single
device, which opens up enormous possibilities to address key
questions about the nature of correlation induced
superconductivity and topology, and allows to create entirely
novel quantum phases with enhanced interactions. In this talk we
will introduce some of the main concepts underlying these
systems, concentrating on magic angle twisted bilayer graphene
(MATBG) and show how symmetry-broken states emerge at all
integer electron fillings [1]. We further will discuss recent
experiments including screened interactions [2], Chern
insulators [4], magnetic Josephson junctions [4], quantum
criticality [5], re-entrant correlated insulators at high
magnetic fields [6] and discuss some of the avenues for novel
quantum sensing applications [7]. <br>
