Quantum impurity models using superpositions of fermionic Gaussian states: Practical methods and applications

The coherent superposition of nonorthogonal fermionic Gaussian states has been shown to be an efficient approximation to the ground states of quantum impurity problems [Bravyi and Gosset, Commun. Math. Phys. 356, 451 (2017)CMPHAY0010-361610.1007/s00220-017-2976-9]. We propose a practical approach fo...
