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…

On the stability of topological order in tensor network states

Dominic J. Williamson, Clement Delcamp, Frank Verstraete +1

We construct a tensor network representation of the 3d toric code ground state that is stable to a generating set of uniform local tensor perturbations, including those that do not…

Fractionalized fermionic quantum criticality in spin-orbital Mott insulators

Urban F. P. Seifert, Xiao-Yu Dong, Sreejith Chulliparambil +3

We study transitions between topological phases featuring emergent fractionalized excitations in two-dimensional models for Mott insulators with spin and orbital degrees of freedom…

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…

Tensor Networks Can Resolve Fermi Surfaces

Quinten Mortier, Norbert Schuch, Frank Verstraete +1

We demonstrate that projected entangled-pair states (PEPS) are able to represent ground states of critical, fermionic systems exhibiting both 1d and 0d Fermi surfaces on a 2D latti…

Robustness of critical U(1) spin liquids and emergent symmetries in tensor networks

Henrik Dreyer, Laurens Vanderstraeten, Ji-Yao Chen +2

We study the response of critical Resonating Valence Bond (RVB) spin liquids to doping with longer-range singlets, and more generally of U(1)-symmetric tensor networks to non-symme…

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…
