Stoner instabilities and Ising excitonic states in twisted transition metal dichalcogenides
Augusto Ghiotto, LingNan Wei, Larry Song +11
Moiré transition metal dichalcogenide (TMD) systems provide a tunable platform for studying electron-correlation driven quantum phases. Such phases have so far been found at ration…
Machine learning-based compression of quantum many body physics: PCA and autoencoder representation of the vertex function
Jiawei Zang, Matija Medvidović, Dominik Kiese +3
Characterizing complex many-body phases of matter has been a central question in quantum physics for decades. Numerical methods built around approximations of the renormalization g…
Compressing the two-particle Green's function using wavelets: Theory and application to the Hubbard atom
Emin Moghadas, Nikolaus Dräger, Alessandro Toschi +7
Precise algorithms capable of providing controlled solutions in the presence of strong interactions are transforming the landscape of quantum many-body physics. Particularly exciti…
Magnetism and Metallicity in Moiré Transition Metal Dichalcogenides
Patrick Tscheppe, Jiawei Zang, Marcel Klett +8
The ability to control the properties of twisted bilayer transition metal dichalcogenides in situ makes them an ideal platform for investigating the interplay of strong correlation…
Real space representation of topological system: twisted bilayer graphene as an example
Jiawei Zang, Jie Wang, Antoine Georges +2
We construct a Wannier basis for twisted bilayer graphene that is projected only from the Bloch functions of the twisted bilayer flat bands. The and symme…

We present a comprehensive dynamical mean field study of the triangular lattice moiré Hubbard model, which is believed to represent the physics of moiré bilayer transition metal di…
Staggered Pseudo Magnetic Field in Twisted Transition Metal Dichalcogenides: Physical Origin and Experimental Consequences
Jie Wang, Jiawei Zang, Jennifer Cano +1
Strong magnetic fields profoundly affect the quantum physics of charged particles, as seen for example by the integer and fractionally quantized Hall effects, and the fractal `Hofs…
Hartree-Fock study of the moiré Hubbard model for twisted bilayer transition metal dichalcogenides
Jiawei Zang, Jie Wang, Jennifer Cano +1
Twisted bilayer transition metal dichalcogenides have emerged as important model systems for the investigation of correlated electron physics because their interaction strength, ca…
Quantum Criticality in Twisted Transition Metal Dichalcogenides
Augusto Ghiotto, En-Min Shih, Giancarlo S. S. G. Pereira +10
In moiré heterostructures, gate-tunable insulating phases driven by electronic correlations have been recently discovered. Here, we use transport measurements to characterize the g…
