There was also some limited work Novelties in string theory the world-sheet or world volume level for the 2T-physics formulation of. Itzhak Bars Research Interests My current interests include mainly String Field Theoryand Two-Time Physicsbut these are related to several other topics in which I am currently active as outlined below. It also suggests a new paradigm for the construction of a fundamental theory that is likely to impact on the quest for unification.

The AdS-CFT approach mainly involves the gauge sector, as opposed to the matter sector treated in my early work. This was motivated by the observations that, on the one hand, a very similar formalism of non-commutative field theory and Chern-Simons type actions emerged naturally in both cases, and on the other hand, bosonized ghosts in string field theory play a role similar to a second timelike coordinate.

We have applied MSFT to both perturbative string physics new results for off-shell string amplitudes and non-perturbative string physics analysis of the true vacuum of string theory, D-branes. Soon afterwards, papers suggesting more timelike dimensions began to.

For technical information please refer to my 2T-physics. It also suggests that the electro-weak phase transition must be driven by a new particle perhaps the dilaton thus leading to a new scenario for the mass generation mechanism that is possibly related to other phase transitions in the history of the universe. I continue to research this general topic in the context of string field theory and cosmology.

The novelty was that string interaction was re-formulated in terms of the simple Moyal product indicative of an induced quantum mechanics which is produced by string joining. Two-Time Physics 2T-physics Starting with the of Two-Time Physics 2T-physicswhich was inspired by 2T in earlier papers since 1995, evidence has been mounting that the ordinary formulation of physics, in a space-time with three space and one time dimensions 1T-physicsis insufficient to describe our world.

Prior to recent success in field theory, the work on 2T-physics since 1998 had mostly concentrated on the worldline Novelties in string theory of particles, and had demonstrated that 2T-physics stands above 1T-physics as a structure that encompasses and explains phenomena which appear very surprising from the point of view of 1T-physics.

The prior work on 2T-physics during 1998-2004 extended the initial concepts in several directions, including, and interactions of particles with electromagnetism, gravity, and all higher spin fields.

To help grasp the relation between 1T-physics and 2T-physics, consider the many possible shadows of a 3 dimensional object projected from different perspectives on the surrounding walls of a 3-dimensional room. It was possible to obtain all exact solutions, including the vacuum solution, when an anomalous term in the energy of the midpoint of the string is neglected. Many attempts have been made over the past 30 years to formulate and develop computational tools in SFT.
