abstract:In quantum field theory, an order operator or an order field is a quantum field version of Landau's order parameter whose expectation value characterizes phase transitions. There exists a dual version of it, the disorder operator or disorder field, whose expectation value characterizes a phase transition by indicating the prolific presence of defect or vortex lines in an ordered phase.
One imagines that EE's executives were desperate to offer Apple just about any deal, in order to be the only operator offering a 4G iPhone in the UK, but it now seems unlikely that will happen.
People can call Greyhound to order a ticket, using a PayNearMe card, read the operator the number on the card, then pay with cash at 7-11 to finalize the purchase of the ticket.
