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 o…

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…
