The flattening of single-particle band structures plays an important role in the quest for novel
quantum states of matter owing to the crucial role of interactions. Recent advances in theory …

We apply a generalized Schrieffer-Wolff transformation to the extended Anderson-like
topological heavy fermion (THF) model for the magic-angle (θ= 1.0 5°) twisted bilayer …

We study quantum-impurity models as a platform for quantum thermometry. A single
quantum spin-1 2 impurity is coupled to an explicit, structured, fermionic thermal sample …

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 …

We investigate the large Kondo coupling limit of the Kondo-Heisenberg model on one-and
two-dimensional lattices. Focusing on the possible superconducting states when slightly …

In lattice models with quadratic finite-range Hermitian Hamiltonians, the inherently non-
Hermitian transfer matrix (TM) governs the band dispersion. The van Hove singularities …

Electron-phonon coupling in magic-angle twisted bilayer graphene is an important but
difficult topic. We propose a scheme to simplify and understand this problem. Weighted by …

In single sheets of graphene, vacancy-induced states have been shown to host an effective
spin-1/2 hole that can be Kondo screened at low temperatures. Here, we show how these …

The transport across a Kondo-correlated quantum dot coupled to two leads with
independent temperatures and chemical potentials is studied using a controlled …

The presence of interlayer potential, Rashba spin–orbit coupling and exchange field in
bilayer graphene leads to a topological phase transition. We theoretically calculate the …
