# The ‘unromantic pictures’ of quantum theory

@article{Tumulka2007TheP, title={The ‘unromantic pictures’ of quantum theory}, author={Roderich Tumulka}, journal={Journal of Physics A: Mathematical and Theoretical}, year={2007}, volume={40}, pages={3245 - 3273} }

I am concerned with two views of quantum mechanics that John S Bell called ‘unromantic’: spontaneous wavefunction collapse and Bohmian mechanics. I discuss some of their merits and report about recent progress concerning extensions to quantum field theory and relativity. In the last section, I speculate about an extension of Bohmian mechanics to quantum gravity.
