    Graduate Renormalization massless phi4 theory in Peskin.

    In Peskin- Schroeder, pag 412: "In massless phi4 theory, the one-loop propagator correction is completely canceled by mass counterterm." So, do massless theory provides mass counterterm? How is it generated? Maybe from a bare mass...don't have any clue. I'm confused because it seems that...

    Graduate Quantum computingnecessary classical devices knowledge?

    Hi, i have just started studying quantum computing. i found it very interesting and i was wondering to dedicate my thesis on it...BUT...i suffer a lack of knowledge about classical computing devices (i'm not talking about the classic works on logic by Turing and Church and so forth)...so..can...
