Correlated Mott semi-metal in the topological heavy fermion model
Emile Pangburn, Igor de Melo Froldi, Anurag Banerjee
The topological heavy-fermion model provides a minimal framework for describing the coexistence of localized moments and itinerant Dirac electrons in magic-angle twisted bilayer gr…
Probing quasiparticle excitations in a doped Mott insulator via Friedel oscillations
Anurag Banerjee, Emile Pangburn, Catherine Pépin +1
In this work, we investigate impurity-induced Friedel oscillations in the doped two-dimensional Hubbard model, focusing on the role of holon and doublon excitations. We show that w…
Impurity-induced Mott ring states and Mott zeros ring states in the Hubbard operator formalism
Emile Pangburn, Anurag Banerjee, Catherine Pépin +1
We study the formation of subgap impurity states in strongly correlated Mott insulators. We use a composite operator method that gives us access to both the bulk Green's function,…
Topological charge excitations and Green's function zeros in paramagnetic Mott insulators
Emile Pangburn, Catherine Pépin, Anurag Banerjee
We investigate the emergence of topological features in the charge excitations of Mott insulators in the Chern-Hubbard model. In the strong correlation regime, treating electrons a…
Charge density wave solutions of the Hubbard model in the composite operator formalism
Anurag Banerjee, Emile Pangburn, Chiranjit Mahato +2
We investigate the charge density wave phase in the strongly correlated Hubbard model without any other broken symmetry phase. Starting from the atomic Hamiltonian with no hopping,…
Spontaneous layer selective Mott phase in the bilayer Hubbard model
Emile Pangburn, Louis Haurie, Sébastien Burdin +2
Quantum materials featuring both itinerant and localized degrees of freedom exhibit numerous exotic phases and transitions that deviate from the Ginzburg-Landau paradigm. This work…
Purely antiferromagnetic frustrated Heisenberg model in spin ladder compound BaFeSe
Roll A., Petit S., Forget A. +4
The spin dynamics in the block magnetic phase of the iron-based ladder compound \bfs\ has been studied by means of single crystal inelastic neutron scattering. Using linear spin wa…
Bands renormalization and superconductivity in the strongly correlated Hubbard model using composite operators method
L. Haurie, M. Grandadam, E. Pangburn +3
We use the composite operator method (COM) to analyze the strongly correlated repulsive Hubbard model, investigating the effect of nearest-neighbor hoppings up to fourth order on a…
Proximity-induced charge density wave in a metallic system
Anurag Banerjee, Louis Haurie, Catherine Pépin
Non-local quasiparticles in correlated quantum materials can exhibit the proximity effect. For instance, in metal superconductor hybrid systems, the leaking of cooper pairs to the…
Incoherent transport in a model for the strange metal phase: Memory-matrix formalism
Emile Pangburn, Anurag Banerjee, Hermann Freire +1
We revisit a phenomenological model of fermions coupled to fluctuating bosons that emerges from finite-momentum particle-particle pairs for describing the strange metal phase in th…
