Physical Spectrum of Compactified Strings

Physical Review Letters, 1985
The single-particle states of compactified bosonic string theory are classified by a direct product of a fundamental representation of the Heisenberg algebra for the noncompact flat dimensions and an affine-g Lie algebra, where the rank of its Lie subalgebra g is the number of internal dimensions and its identity depends on their length scales.

STRING FIELD THEORY AND PHYSICAL INTERPRETATION OF D=1 STRINGS

Modern Physics Letters A, 1990
We describe a field theoretic formulation for one-dimensional string theory. It is given by the collective field representation of the matrix model and leads to a physical interpretation of the theory as that of a massless scalar field in two dimensions.

Stringing physics along

Physics World, 2007
"Hypotheses non fingo," wrote Isaac Newton 300 years ago in the second edition of his Principia Mathematica. It has been variously translated as "I do not make hypotheses" or "I do not feign hypotheses". Instead, Newton established laws of nature such as his theory of universal gravitation – simple, economical equations of broad explanatory power able ...

General Relativity, Strings, and Mathematical Physics

Letters in Mathematical Physics, 1999
This article is a review of string theory in the quantization of gravity and the unification of fundamental forces. There is a lot to condense into such a brief article so only the barest outline is given. Nevertheless, the reader will find many key points with pertinent citations.

Physics and Mathematics of Strings

1990
Vadim Knizhnik was one of the most promising theoretical physicists in the world. Unfortunately, he passed away at the very young age of 25 years. This memorial volume is to honor his contributions in Theoretical Physics. This is perhaps one of the most important collections of articles on the theoretical developments in String Theory, Conformal Field ...

String Theory and Particle Physics

2012
String theory is one of the most active branches of theoretical physics and has the potential to provide a unified description of all known particles and interactions. This book is a systematic introduction to the subject, focused on the detailed description of how string theory is connected to the real world of particle physics.

Physical Synthesis of Bowed String Instruments

2007
This chapter describes how bowed string instruments such as the violin, viola, cello, and bass can be modeled using equations that describe their most significant physical attributes. It discusses the structure of a bowed string instrument and presents a description of the development of the research on vibrating strings.

A STRING MODEL WITH ONE PHYSICAL STATE

Modern Physics Letters A, 1994
Further investigation on a bosonic string model with second class constraints is carried out. The physical space of the model is built up. It is shown, using analogy with the point particle with additional space-time gauge symmetry, that there is only one physical state in the model corresponding to an antisymmetric second rank tensor.
