>> DIEP focus session May 25th 2018
Jácome Armas, DIEP & UvA
On the DIEP concept and structure (and notions of emergence)
Jácome coordinates some of the DIEP effort and works on string theory, black holes, hydrodynamics and elastic membranes. In this talk he presents the original debate within modern physics of reductionism versus emergentism starting with Dirac and ending in Anderson. He gives a catalog of the plurality of definitions of emergence that have been proposed in the literature and finally he mentions the research questions that DIEP is interested in.
Vijay Balasubramanian, U. Penn
From brains to black holes: information and emergent phenomena
Vijay works on string theory and holography investigating how gravity, space and time emerge from quantum theory. But his investigations on fundamental questions such as these have led him to study information processing in biophysics and the brain. Besides being an active high energy physicist, he is the head of a group on biophysics.
Find out how one goes from strings to the brain.
Alix McCollam, DIEP & Radboud U.
What can condensed matter do for emergence?
Alix works on condensed matter and new emergent phases of matter. Her talk will give a broad overview of such phases that arise from strong electron-electron interactions such as unconventional superconductivity, exotic types of magnetic and electric order as well as quantum criticality. Alix will argue that condensed matter can be an excellent tool for the study of emergence, where, by means of experiments, emergent states can be characterised in detail, some of which are still lacking a proper microscopic understanding.
Frank Redig, TU Delft
Frank works on probability theory and the emergence of macro-dynamics from statistical systems, which can be viewed as an instance of the laws of large numbers. Examples of emergent dynamics include hydrodynamics but also universal equations such as the heat equation emerging from the chaotic motion of molecules. Frank is also interested in how accurate these equations are and the universality of the fluctuations around it.
Joop Schaye, Leiden U.
Simulating the universe
Joop works on the structural formation of large cosmological structures such as galaxies by means of hardcore numerical simulations that mimmic the beginning period of the evolution of the universe. He is interested in the emergence of the cosmic web and the relations between black holes and galaxies. Joop will be discussing different aspects of emergent phenomena that appear in cosmology, including self-organisation processes at cosmological scales.
Daan Frenkel, Cambridge U.
Merging and emerging behaviour in us and around us
Daan works on the interface between chemistry, soft condensed matter and nano materials, developing new methods for numerically simulating large classes of physical systems at different length scales which exhibit different types of emergent behaviour: nucleation in colloids, phase transitions in DNA molecules and self-assembly in proteins. Through his work you will find out how so many different sciences are interconnected at different scales.
