DESCRIPTION:Magic Angle Twisted Bilayer Graphene (TBG)\, two graphene layer
 s with a relaIve twist angle ~1&ordm\;\, features very flat bands close to
  the Fermi level\, which are highly suscepIble to the effects of the elect
 ronic interacIons. A plethora of correlated phenomena appear as a function
  of doping\, temperature and magnetic field. The so-called cascades\, a se
 ries of asymmetric resets in the Scanning Tunneling Microscope (STM) Spect
 rum and the inverse compressibility of Twisted Bilayer Graphene (TBG) arou
 nd integer fillings [1]\, remain up to tens of Kelvin and constitute the m
 ost resilient correlated phenomena in TBG together with the resisIve state
 s as a function of doping.\nAfter introducing the phenomenology of the cas
 cades\, I will first show that the cascade signatures in STM\, compressibi
 lity and transport experiments can be explained\, within a heavy fermion d
 escription\, in terms of the formaIon of local moments and heavy quasipart
 icles in the normal state [2\,3]\, i.e. without the need to invoke symmetr
 y breaking\, which experimentally has been unambiguously detected only bel
 ow a few kelvin. I will then introduce novel ways to probe the cascade phe
 nomena\, such as optical probes [3] and the Atomic-SET and discuss the ang
 le dependence of this phenomenon.\n&nbsp\;
