Quantum Economics and Finance: An Applied Mathematics Introduction Orrell (the co-author of Paul Wilmot's Newton Gravity book I think)
looks interesting
series of books on quantum-finance/economics now recently
Quantum Markets: Physical Theory of Market Microstructure Sarkissan
Quantum Finance: Intelligent Forecast and Trading Systems Lee
Mathematical Methods and Quantum Mathematics for Economics and Finance Baaquie
Quantum Field Theory for Economics and Finance Baaquie
older
Quantum Finance: Path Integrals and Hamiltonians for Options and Interest Rates Baaquie
and when finally understanding finance one can develop physics
Physics from Finance: A gentle introduction to gauge theories, fundamental interactions and fiber bundles Schwichtenbe
My dream is to arbitrage out Minkowski space-time and the Schwarzschild metric using space-time built from the very quantum level. Don't discuss your theory, arbitrage out the competing theories without they knowing about it.
