Events at the Dutch Institute for Emergent Phenomena
Bringing emergence to scientists and to the world
DIEP is a broad interdisciplinary endeavour with the aim of bringing scientists together and fostering collaborations in order to progress the science of emergence. For this purpose, DIEP organises a wide variety of events, ranging from brainstorming sessions, community building events, workshops, conferences, public lectures, technical talks and cocktail parties. Regular events include DIEP seminars.
>> December 20th 2018: DIEP colloquium with Andrea Cavalleri
Time: 16:00-17:00 | Location: UvA, Science Park, room C0.110
Hosts: Mark S. Golden and Erik van Heumen
Andrea Cavalleri is professor at the Max Planck Institute for the Structure and Dynamics of Matter at Hamburg and at the Department of Physics at the University of Oxford. As part of his stay he will be giving a talk on his recent work on photoinduced superconductivity (see title and abstract below). Drinks are provided after the colloquium at the FNWI foyer.
Abstract: Photoinduced superconductivity and other stories
In this lecture, I will discuss how coherent electromagnetic radiation at infrared and TeraHertz frequencies can be used to drive coherently and to large amplitudes interesting collective excitations in solids. The nonlinear cooperative response of low-frequency excitations is largely unexplored and can yield new types functional control. I will for example discuss experiments in which superconducting fluctuations can be amplified by light at temperatures higher than the thermodynamic transition temperature. I will also discuss how X-ray Free Electron Lasers are integral to this work, and how they can be used to sample the dynamical evolution of crystal lattices and of other microscopic parameters in time.
>> October 1st 2018: Talk by Amos Yarom
Time: 15:00-16:00 | Location: UvA, Science Park, room C4.174
Amos Yarom is a professor at Technion- Israel Institute of Technology and has made significant contributions to hydrodynamics and black holes. He be visiting DIEP from the 30th September to the 1st of October 2018 (more info here). As part of his stay he will be giving a talk on his recent work on hydrodynamics (see title and abstract below).
Abstract: New constraints on transport from Schwinger Keldysh theory
After a review of a novel low energy effective action for the Schwinger-Keldysh generating function, I will describe how it captures information on the entropy current, Onsager relations, and new constraints on transport.
>> 20th September 2018: IoP colloquium by Sebastian Huber
Time: 16:00-17:00 | Location: University of Amsterdam, Science Park, CWI’s Turingzaal
Sebastian Huber (ETH Zurich) will be visiting DIEP from the 20th-21st of September 2018 (details here). He works on topomechanics, driven systems and condensed matter theory. On September 21st, Sebastian will be giving a broad lecture (see title and abstract below) on topological mechanics.
Abstract: Topological mechanics
The elastic properties of materials are determined by a few material constants such as the Young’s modulus. Using super-structures one can effectively change these “constants”. In this way we obtain functionalities such as wave-guiding, acoustic lensing or programmable failure. I will show how topological band theory, known from the description of electrons in solids, provides us with a powerful design-principle for such mechanical metamaterials. Moreover, mechanical metamaterials offer a powerful platform for the study of fundamentally new phenomena that are hard to observe in other arenas. Here, I will highlight the first measurement of a quadrupole topological insulator in a silicon-based metamaterial and the implementation of an axial gauge field in an acoustic Weyl system.
