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,…
Charge modulation in the background of depleted superconductivity inside vortices
Chiranjit Mahato, Anurag Banerjee, Catherine Pépin +1
We use the Bogoliubov-de Gennes (BDG) formalism to undertake a microscopic investigation of a vortex lattice in a strongly correlated, type-II, d-wave superconductor (SC) treating…
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…
Superconductivity in twisted bilayer graphene: possible pairing symmetries, impurity-induced states and Chern number
Emile Pangburn, Miguel Alvarado, Oladunjoye A. Awoga +2
We consider the most energetically favorable symmetry-allowed spin-singlet and spin-triplet superconducting pairing symmetries in twisted bilayer graphene at the magic angle, whose…
Strange metallicity in an antiferromagnetic quantum critical model: A sign-problem-free quantum Monte-Carlo study
Rafael M. P. Teixeira, Catherine Pépin, Hermann Freire
We compute transport and thermodynamic properties of a two-band spin-fermion model describing itinerant fermions in two dimensions interacting via antiferromagnetic quantum c…
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…
Superconductivity in monolayer and few-layer graphene: III Impurity-induced subgap states and quasi-particle interference patterns
Emile Pangburn, Louis Haurie, Adeline Crépieux +5
We consider the most energetically favorable symmetry-allowed spin-singlet and spin-triplet superconducting pairing symmetries in monolayer and few-layer graphene, and for each cal…
Superconductivity in monolayer and few-layer graphene: I. Review of possible pairing symmetries and basic electronic properties
Emile Pangburn, Louis Haurie, Adeline Crépieux +4
We review all symmetry-allowed spin-singlet and spin-triplet superconducting (SC) order parameters in graphene (-wave, -wave, -wave, and -wave) generated by generic ons…
Superconductivity in monolayer and few-layer graphene: II. Topological edge states and Chern numbers
Adeline Crépieux, Emile Pangburn, Louis Haurie +5
We study the emergence of electronic edge states in superconducting (SC) monolayer, bilayer, and trilayer graphene for both spin-singlet and spin-triplet SC order parameters. We fo…
Charge order and emergent symmetries in cuprate superconductors
C. Pépin, H. Freire
In this paper, we present our studies of the phase diagram of the cuprate superconductors performed in recent years. We describe how a few field-theoretical concepts can be used to…
Charge, bond, and pair density wave orders in a strongly correlated system
Anurag Banerjee, Catherine Pépin, Amit Ghosal
The coexistence of multiple quasi-degenerate orders is the hallmark of the strongly correlated materials. Experiments often reveal several spatially modulated orders in the underdo…
Pseudogap phase and fractionalization: Predictions for Josephson junction setup
Anurag Banerjee, Alvaro Ferraz, Catherine Pépin
The pseudogap regime of the underdoped cuprates arguably remains one of the most enigmatic phenomena of correlated quantum matter. Recent theoretical ideas suggest that a pair dens…
Pseudo-spin Skyrmions in the Phase Diagram of Cuprate Superconductors
Corentin Morice, Debmalya Chakraborty, Xavier Montiel +1
Topological states of matter are at the root of some of the most fascinating phenomena in condensed matter physics. Here we argue that skyrmions in the pseudo-spin space related to…
Evolution of spectral and transport quantities with doping in the SU(2) theory of cuprates
Corentin Morice, Xavier Montiel, Catherine Pépin
Recent transport experiments in the cuprate superconductors linked the opening of the pseudogap to a change in electronic dispersion [S. Badoux et al., Nature 531, 210 (2015)]. Tra…
Realization of Haldane's Exclusion Statistics in a Model of Electron-Phonon Interactions
Catherine Pépin, Alexei M. Tsvelik
We discuss an integrable model describing one-dimensional electrons interacting with two-dimensional anharmonic phonons. In the low temperature limit it is possible to decouple pho…
