Highly sensitive and selective detection of vapour-phase analytes at low concentration has wide-ranging applications in many environments. Chemiresistors offer the potential to fulfill many of the requirements of a portable, low cost device. In order

Using exact diagonalization, we study the projected Hamiltonian with Coulomb interaction in the 8 flat bands of first magic angle twisted bilayer graphene. Employing the U(4) (U(4)$\times$U(4)) symmetries in the nonchiral (chiral) flat band limit, we

We find exact analytic expressions for the energies and wave functions of the charged and neutral excitations above the exact ground states (at rational filling per unit cell) of projected Coulomb Hamiltonians in twisted bilayer graphene. Our exact e
