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…

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…
