Remarks on Cosmic Strings and Quantum Gravity
Jeeva S. Anandan
A quantum equivalence principle is formulated by means of a gravitational phase operator which is an element of the Poincare group. This is applied to the spinning cosmic string wh…
Quantum Measurement Problem and the Possible Role of the Gravitational Field
Jeeva Anandan
The quantum measurement problem and various unsuccessful attempts to resolve it are reviewed. A suggestion by Diosi and Penrose for the half life of the quantum superposition of tw…
Classical and Quantum Physical Geometry
Jeeva S. Anandan
The task of quantizing gravity is compared with Einstein's relativization of gravity. The philosophical and physical foundations of general relativity are briefly reviewed. The Ehl…
REALITY AND GEOMETRY OF STATES AND OBSERVABLES IN QUANTUM THEORY
J. Anandan
The determination of the quantum state of a single system by protective observation is used to justify operationally a formulation of quantum theory on the quantum state space (pro…
