Graph Neural Networks for Fast Operator Selection in Adaptive VQE
Javad Vahedi, Hadi H. Arefi
Adaptive variational quantum algorithms like ADAPT-VQE construct tailored ansätze by iteratively selecting operators from a pool using gradient-based criteria. While this avoids ov…
Parafermionic Truncated Wigner Approximation
Javad Vahedi, Martin Garttner
We introduce the parafermionic truncated Wigner approximation (TWA), a semiclassical phase-space framework for simulating the nonequilibrium dynamics of lattice systems with fra…
Electronic structure and transport in materials with flat bands: 2D materials and quasicrystals
Guy Trambly de Laissardière, Somepalli Venkateswarlu, Ahmed Missaoui +9
In this review, we present recent works on materials whose common point is the presence of electronic bands of very low dispersion, called "flat bands", which are due to specific a…
Magnetism of magic-angle twisted bilayer graphene
Javad Vahedi, Robert Peters, Ahmed Missaoui +2
We investigate magnetic instabilities in charge-neutral twisted bilayer graphene close to so-called "magic angles" using a combination of real-space Hartree-Fock and dynamical mean…
The Hubbard model on the honeycomb lattice: from static and dynamical mean-field theories to lattice quantum Monte Carlo simulations
Marcin Raczkowski, Robert Peters, Th\d{i} Thu Phùng +4
We study the one-band Hubbard model on the honeycomb lattice using a combination of quantum Monte Carlo (QMC) simulations and static as well as dynamical mean-field theory (DMFT).…
