Strain-induced quantum phase transitions in magic angle graphene
Daniel E. Parker, Tomohiro Soejima, Johannes Hauschild +2
We investigate the effect of uniaxial heterostrain on the interacting phase diagram of magic-angle twisted bilayer graphene. Using both self-consistent Hartree-Fock and density-mat…
Soft modes in magic angle twisted bilayer graphene
Eslam Khalaf, Nick Bultinck, Ashvin Vishwanath +1
We present a systematic study of the low-energy collective modes for different insulating states at integer fillings in twisted bilayer graphene. In particular, we provide a simple…
Lattice regularisation and entanglement structure of the Gross-Neveu model
Gertian Roose, Nick Bultinck, Laurens Vanderstraeten +3
We construct a Hamiltonian lattice regularisation of the -flavour Gross-Neveu model that manifestly respects the full symmetry, preventing the appearance of any…
Efficient simulation of moire materials using the density matrix renormalization group
Tomohiro Soejima, Daniel E. Parker, Nick Bultinck +2
We present an infinite density-matrix renormalization group (DMRG) study of an interacting continuum model of twisted bilayer graphene (tBLG) near the magic angle. Because of the l…
Flat band topology of magic angle graphene on a transition metal dichalcogenide
Tianle Wang, Nick Bultinck, Michael P. Zaletel
We consider twisted bilayer graphene on a transition metal dichalcogenide substrate, where proximity-induced spin-orbit coupling significantly alters the eight flat bands which occ…
Spin-triplet superconductivity from inter-valley Goldstone modes in magic-angle graphene
Vladyslav Kozii, Michael P. Zaletel, Nick Bultinck
We consider magic-angle graphene in the doping regime around charge neutrality and study the connection between a recently proposed inter-valley coherent insulator at zero doping a…
Charged Skyrmions and Topological Origin of Superconductivity in Magic Angle Graphene
Eslam Khalaf, Shubhayu Chatterjee, Nick Bultinck +2
Spontaneous symmetry breaking plays a pivotal role in many areas of physics, engendering a variety of excitations from sound modes in solids to pions in nuclear physics. Equally im…
