ABSTRACT: In a recent paper we have studied the Hamiltonian and path integral quantizations of the conformally gauge-fixed Polyakov D1 brane action in the instant-form of dynamics using the equal ...

String theory has long been presented as physicists' best candidate for describing the fundamental nature of the Universe. Yet, at the beginning of the 21st century, it became apparent that most ...

He arrived onstage without a violin — neither his 1714 Soil Stradivarius nor his Guarneri del Gesu 1743 Sauret, which he has played on concert stages around the world — and still gave a command ...
