Synopsis of talk

Quantum mechanics is a theory of wave functions in Hilbert space. Many features that we generally take for granted when we use quantum mechanics -- classical spacetime, locality, the system/environment split, collapse/branching, preferred observables, the born rule for probabilities -- should in principle be derivable from the basic ingredients of the quantum state and the Hamiltonian. I will discuss recent progress on these problems, including consequences for quantum gravity and emergent spacetime. 

About Sean Carroll

Sean Carroll

Sean Carroll is a well-known American theoretical physicist, specialising in quantum mechanics, cosmology, statistical mechanics, and the foundations of physics. He is Research Professor of Physics at Caltech and External Professor at the Santa Fe Institute.

His latest book, Something Deeply Hidden, is about quantum mechanics, Many Worlds, and the emergence of spacetime. And he also has a regular podcast, called Mindscape, in which he interviews all sorts of fascinating and smart people.


This seminar has been organised by the Quantum Foundations Centre.
