Research Interests
My current interests include String Field Theory
(SFT), and TwoTime
Physics (2TPhysics) and Cosmology.
My long term goal is the construction of the unified theory at the fundamental
level.
My research is driven by some of the current questions in Cosmology, the Standard Model of elementary particles, and unification of forces including quantum gravity in the framework of string theory or Mtheory. The mysteries that are hoped to be resolved include the physics of the very early universe and how it determined the gauge symmetries (forces) and the families of quarks and leptons (matter) that we observe today. Once the fundamental theory is constructed it is likely that it will suggest the best approach to answer our current mysteries, including dark matter, dark energy and a host of issues related to masses and interactions of quarks, leptons and force particles.
All the physics we know with
certainty today at microscopic or macroscopic distance scales is embodied in
principle in the fundamental laws described by the Standard Model of Particles
and Forces, and in General Relativity.
In 2006 I discovered the 2T Standard Model and in 2008 2TGravity,
both in 4space and 2time dimensions. Supersymmetric 2Tfield theory in 4+2 dimensions has
also been achieved during 20072009. From the point of view of these 2T field
theories, as well as 2T particle dynamics that I developed since 1995, all
known physical phenomena experienced in 3space and 1time dimensions, as
described in 1Tphysics, appear as various “shadows” of phenomena in 4+2
dimensions. 2Tphysics captures “hidden” properties of physical systems in 3+1
dimensions that are systematically missed by the usual 1Tphysics formulation
(see simplest example).
The existence of such verifiable predictions, that 1Tphysics can only confirm
but cannot foresee systematically, show that 2TPhysics is a larger unifying
framework and an unavoidable completion of 1Tphysics. I therefore expect that
the methods of 2Tphysics will prove to be essential in the construction of the
ultimate unified theory as well as in a more complete description of all
physics at all scales of distance or of energy.
I emphasize symmetries and supersymmetries in much of
my research on particle physics, field theory and string theory. From time to
time the symmetry structures in physics have led me to discover new physical
concepts, such as TwoTime Physics (2TPhysics), as well as a few new structures
in Mathematics or Mathematical Physics, in particular in supergroups, noncompact groups, and noncommutative
geometry. This activity also took me on side trips into applications of
symmetries in other fields of physics. Consequently, supersymmetry in nuclear physics was experimentally
confirmed as an approximate symmetry of bosonic and fermionic nuclei.
Some of the theoretical computations I did in the past on the Standard Model,
gauge theories, and grand unification, are currently of experimental interest.
In particular the first computation of the weak interaction contribution to the
anomalous
magnetic moment of the muon has recently been
confirmed by measurements performed more than 30 years later.
