      abstract     = {Twisted bilayer graphene (tBLG) near the magic angle is a
                      unique platform where the combination of topology and strong
                      correlations gives rise to exotic electronic phases. These
                      phases are gate-tunable and related to the presence of flat
                      electronic bands, isolated by single-particle band gaps.
                      This enables gate-controlled charge confinements, essential
                      for the operation of single-electron transistors (SETs), and
                      allows one to explore the interplay of confinement, electron
                      interactions, band renormalization, and the moiré
                      superlattice, potentially revealing key paradigms of strong
                      correlations. Here, we present gate-defined SETs in tBLG
                      with well-tunable Coulomb blockade resonances. These SETs
                      allow us to study magnetic field-induced quantum
                      oscillations in the density of states of the source-drain
                      reservoirs, providing insight into gate-tunable Fermi
                      surfaces of tBLG. Comparison with tight-binding calculations
                      highlights the importance of displacement-field-induced band
                      renormalization crucial for future advanced gate-tunable
                      quantum devices and circuits in tBLG including, e.g.,
                      quantum dots and Josephson junction arrays.},
