Bruno Nachtergaele, Vipul Periwal
It is shown that certain natural quantum logic gates, {\it i.e.} unitary time evolution matrices for spin-\frac{1}{2} quantum spins, can be represented as sums, with appropriate ph…

On the flux phase conjecture at half-filling: an improved proof
Nicolas Macris, Bruno Nachtergaele
We present a simplification of Lieb's proof of the flux phase conjecture for interacting fermion systems -- such as the Hubbard model --, at half filling on a general class of grap…
