Identity and Self as Physical Signatures of Life in Dictyostelium and Multicellular Systems
Yehuda Roth
In previous work we sought to address the fundamental question ``What is life?''. Building on that conceptual foundation, we here integrate traditional criteria for living systems…
Fock-Space Formulation of the Lifetime of a Unicellular Organism
Yehuda Roth
What is life? In this work, we take life to mean a dynamical tendency to conserve identity for as long as possible. For a single bacterium, identity is carried by its chromosomal D…
Classical Coherence and Biological Aging

In previous work it was argued that the cells of a multicellular organism form a classically coherent system and that such coherence is essential for life. Here we make this claim…
Classical Coherence Distinguishes Organisms from Colonies
Yehuda Roth
What distinguishes a multicellular organism from a colony? In the first scenario, individual cells belong to the whole; their function is defined only within the organismal context…
