Quantum ontology and the arrow of time

Running across all of our research, this theme focuses on the arrow of time in quantum mechanics and aims to find a coherent answer to the question: what, in quantum mechanical terms, is life?

Research aims

In this research theme we will take a philosophical view of the projects we are undertaking across ‘Life on the Edge’, examining what ‘irreversibility’ means in terms of quantum mechanical models of proteins and enzymes and what, if anything, is special about these regimes of scale, complexity and energy. Another question is whether, and to what extent, it fits within the general characterisation of living systems.

The aim of this theme is to encourage cross-fertilisation between fields, helping to build an interdisciplinary perspective of quantum biology. The ideas will be discussed at philosophical debates and workshops, and disseminated through a series of papers.
