Toy Models for Retrocausality
Speaker(s): Huw Price
Abstract:

Causality and Information Flow in Quantum Protocols
Speaker(s): Samson Abramsky
Abstract: In recent work with Bob Coecke and others, we have developed a categorical axiomatization of quantum mechanics. This analyzes the main structural features of quantum mechanics into simple and general elements, which admit an elegant diagrammatic representation. This enables an illuminating and effec... read more

Time and the big bang
Speaker(s): Neil Turok
Abstract: The evidence for the big bang is now overwhelming. However, the basic question of what caused the bang remains open. One possibility is that time somehow 'emerged,' placing the universe in an inflationary state. Another, perhaps more conservative possibility, is that the big bang was a violent event... read more

Solved and unsolved problems of time in quantum gravity
Speaker(s): Rafael Sorkin
Abstract: I will identify six 'problems of time' that arise in connection with quantum gravity and review the extent to which some of them can be regarded as solved, highlighting the very different aspects that they assume depending on one's starting point: Hamiltonian vs. path-integral, discrete vs continuou... read more

Theory Confirmation in One World and its Failure in Many
Speaker(s): Adrian Kent
Abstract: I discuss how we can give a satisfactory account of theory confirmation for theories with random data, such as Copenhagen quantum theory, despite the lack of a completely satisfactory definition of probabilistic theories of nature. I also explain why neither this nor any other proposed account of sc... read more

On the reality of time and the evolution of laws
Speaker(s): Lee Smolin
Abstract: There are a number of arguments in the philosophical, physical and cosmological literatures for the thesis that time is not fundamental to the description of nature. According to this view, time should be only an approximate notion which emerges from a more fundamental, timeless description only in ... read more
