DESCRIPTION:Benjamin Feldman\nAssistant Professor of Physics\nStanford Univ
 ersity\n\nThermodynamic sensing of correlated phases in twisted transition
  metal dichalcogenides\n\nThe twist angle between adjacent two-dimensional
  layers provides a powerful tuning knob to tailor electronic properties. W
 hen two materials have similar lattice constants and low interlayer twist\
 , a moiré superlattice develops and can lead to flat electronic bands whi
 ch host a variety of interaction-driven phases. In this talk\, I will desc
 ribe electronic compressibility measurements with a scanning single-electr
 on transistor that reveal novel ground states and excitations in twisted s
 emiconducting transition metal dichalcogenides. In twisted double bilayer 
 WSe2\, probing the energy gaps of the correlated insulating states as a fu
 nction of magnetic and electric field allows us to determine their spin an
 d valley character as well as identify itinerant spin polaron excitations.
  I will also present recent measurements of a device with a long moiré wa
 velength which reveal an intricate phase diagram of correlated states as a
  function of carrier density and magnetic field. I will discuss how these 
 findings reflect the interplay between electronic interactions and the nat
 ure of the underlying moiré bands.\n\nHosted by Katja Nowack and Valla Fa
