Krylov variational quantum algorithm for first principles materials simulations
Francois Jamet, Abhishek Agarwal, Carla Lupo +3
We propose an algorithm to obtain Green's functions as a continued fraction on quantum computers, which is based on the construction of the Krylov basis using variational quantum a…
From Slater to Mott physics: epitaxial engineering of electronic correlations in oxide interfaces
Carla Lupo, Evan Sheridan, Edoardo Fertitta +3
Using spin-assisted ab-initio random structure searches, we explore an exhaustive quantum phase diagram of archetypal interfaced Mott insulators, i.e. lanthanum-iron and lanthanum-…
Maximally Localized Dynamical Quantum Embedding for Solving Many-Body Correlated Systems
Carla Lupo, François Jamet, Terence Tse +2
We present a quantum embedding methodology to resolve the Anderson impurity model in the context of dynamical mean-field theory, based on an extended exact diagonalization method.…
Emergence of novel magnetic order at finite temperature in overdoped pnictides
Carla Lupo, Thomas Julian Roberts, Cedric Weber
We examine the temperature dependence of the magnetic ordering in the frustrated Heisenberg model in presence of two different kind of dopants: vacancies or magnetic impu…
Nanoscopic time crystal obtained by nonergodic spin dynamics
Carla Lupo, Cedric Weber
We study the far-from-equilibrium properties of quenched magnetic nanoscopic classical spin systems. In particular, we focus on the interplay between lattice vibrations and magneti…
