We use the topological heavy fermion (THF) model and its Kondo lattice (KL) formulation to
study the possibility of a symmetric Kondo (SK) state in twisted bilayer graphene. Via a large …

Among the variety of correlated states exhibited by twisted bilayer graphene, cascades in
the spectroscopic properties and in the electronic compressibility occur over larger ranges of …

A number of interesting physical phenomena have been discovered in magic-angle twisted
bilayer graphene (MATBG), such as superconductivity, correlated gapped and gapless …

We study theoretically the magic-angle twisted bilayer graphene with proximity-induced
Ising and Rashba spin-orbit couplings on the top layer. Topological flat bands (with three …

Recent scanning tunneling microscopy experiments in twisted bilayer [KP Nuckolls et al.,
Nature (London) 620, 525 (2023) 0028-0836 10.1038/s41586-023-06226-x] and trilayer [H …

We develop an analytic theory to describe the interaction between electrons and K phonons
and study its influence on superconductivity in the bare bands of twisted bilayer graphene …

Counterintuitive temperature dependence of isospin flavor polarization has recently been
found in twisted bilayer graphene, where unpolarized electrons in a Fermi liquid become a …

Motivated by the recent studies of intrinsic local moments and Kondo-driven phases in
magic-angle twisted bilayer graphene, we investigate the renormalization of Kondo coupling …

The experimental discovery of fractional Chern insulators (FCIs) in rhombohedral pentalayer
graphene twisted on hexagonal boron nitride (hBN) has preceded theoretical prediction …

Helical trilayer graphene (hTG) exhibits a supermoiré pattern with large domains centered
around stacking points ABA and BAB, where two well-separated low-energy bands appear …
