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…
Universal tripartite entanglement in one-dimensional many-body systems
Yijian Zou, Karthik Siva, Tomohiro Soejima +2
Motivated by conjectures in holography relating the entanglement of purification and reflected entropy to the entanglement wedge cross-section, we introduce two related non-negativ…
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…
Performance of the rigorous renormalization group for first order phase transitions and topological phases
Maxwell Block, Johannes Motruk, Snir Gazit +4
Expanding and improving the repertoire of numerical methods for studying quantum lattice models is an ongoing focus in many-body physics. While the density matrix renormalization g…
Skyrmion Superconductivity: DMRG evidence for a topological route to superconductivity
Shubhayu Chatterjee, Matteo Ippoliti, Michael P. Zaletel
It was recently suggested that the topology of magic-angle twisted bilayer graphene's (MATBG) flat bands could provide a novel mechanism for superconductivity distinct from both we…
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…
Experimental determination of the energy per particle in partially filled Landau levels
Fangyuan Yang, Alexander A. Zibrov, Ruiheng Bai +4
We describe an experimental technique to measure the chemical potential, , in atomically thin layered materials with high sensitivity and in the static limit. We apply the techn…
Visualizing delocalized correlated electronic states in twisted double bilayer graphene
Canxun Zhang, Tiancong Zhu, Salman Kahn +12
The discovery of interaction-driven insulating and superconducting phases in moiré van der Waals heterostructures has sparked considerable interest in understanding the novel corre…
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…
Phases of the (2+1) dimensional SO(5) non-linear sigma model with topological term
Zhenjiu Wang, Michael P. Zaletel, Roger S. K. Mong +1
We use the half-filled zeroth Landau level in graphene as a regularization scheme to study the physics of the SO(5) non-linear sigma model subject to a Wess-Zumino-Witten topologic…
