Wednesday, 10 May 2017, 18:00-19:30, Room L107 at 2, Rue De-Candolle:

Karim Thébault (Bristol): Cosmic singularity resolution via quantum evolution

and

Thursday, 11 May 2017, 16:15-17:45, Room B002, Uni Bastions:

Karim Thébault (Bristol): Prolegomenon to a philosophy of analogue experiment

Anyone who wishes to attend is welcome.

Karim Thébault (Bristol): Cosmic singularity resolution via quantum evolution

Abstract: We offer a new proposal for singularity resolution in quantum cosmology based upon quantum evolution. In particular, we advocate a new approach to the quantization of mini-superspace leading to a Schrödinger equation for the universe. For models with a massless scalar field and positive cosmological constant, we show that well-behaved quantum observables can be constructed, that generic solutions to this equation are singularity-free and that specific solutions display novel phenomenology including a cosmic bounce.

In terms of technical difficulty, this talk rates 4/5

Karim Thébault (Bristol): Prolegomenon to a philosophy of analogue experiment

Abstract: This will be an informal talk about empirical confirmation in so-called “analogue systems”, which are used to simulate e.g. a black hole by a tabletop experiment in a terrestrial lab.
