How can we prove that the Loewner order does not have the lattice property?
I know that it does not but I couldn't find a reference included the proof. I would appreciate a proof or an address to it.

Theorem 1.1 of Nikolas Stott's paper states:
Partial orders with this property are also called "anti-lattices". The proof can be found in Theorem 6 of Kadison's paper.
