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…

Numerical identification and gapped boundaries of abelian fermionic topological order

Nick Bultinck

In this work we consider general fermion systems in two spatial dimensions, both with and without charge conservation symmetry, which realize a nontrivial fermionic topological ord…
