Probing the Fermi Sea Topology in a Quantum Gas
Cyprien Daix, Pok Man Tam, Maxime Dixmerias +5
Pauli's exclusion principle forces fermions to occupy distinct quantum states, creating a filled region of momentum space at low temperature, the Fermi sea, whose topology governs…

Topological Density Correlations in a Fermi Gas
Pok Man Tam, Charles L. Kane
A Fermi gas of non-interacting electrons, or ultra-cold fermionic atoms, has a quantum ground state defined by a region of occupancy in momentum space known as the Fermi sea. The E…
