An integrated neural wavefunction solver for spinful Fermi systems
Alexander Avdoshkin, Max Geier, Liang Fu
We present an approach to solving the ground state of Fermi systems that contain spin or other discrete degrees of freedom in addition to continuous coordinates. The approach combi…
Geometric bound on structure factor
Yugo Onishi, Alexander Avdoshkin, Liang Fu
We show that a quadratic form of quantum geometric tensor in -space sets a bound on the term in the static structure factor at small . Bands that saturate…
Geometry of degenerate quantum states, configurations of -planes and invariants on complex Grassmannians
Alexander Avdoshkin
Understanding the geometric information contained in quantum states is valuable in various branches of physics, particularly in solid-state physics when Bloch states play a crucial…
Beyond the Berry Phase: Extrinsic Geometry of Quantum States
Alexander Avdoshkin, Fedor K. Popov
Consider a set of quantum states parameterized by taken from some parameter space . We demonstrate how all geometric properties of this manifold of states a…
