Sommerfeld Theory Colloquium (ASC) Podcast
1) Cosmological singularities, quantum chaos and prime numbers
At a singularity the continuum description of spacetime breaks down and one can hope that the microscopic constituents will be revealed. Over 50 years ago, Belinski-Khalatnikov-Lifshitz (BKL) argued t...Show More
2) Active feedback and functionality in model tissues
In the development of animals, tissues self-organise starting from a single cell into lay- ers, shapes and patterns. This active mechanical process operates beyond the theoretical framework of reactio...Show More
3) Mystery of highest energy particles in the Universe
Ultra-High-Energy Cosmic Rays (UHECRs) are particles with energies up to $3\times 10^20 eV$, originating from unknown sources and producing extensive air showers in Earth's atmosphere. In this talk, I...Show More
4) Ecology and Perpetual Evolution in High Dimensions
In a simple, constant environment does evolution continue forever? Does extensive diversification via small genetic and ecological differences? What are general evolutionary consequences of organismic...Show More
5) Activating quantum matter
In driven open quantum matter, coherent many-body quantum dynamics, drive, and dissipation play equally significant roles. These systems span a wide range of examples, including cold atomic gases, exc...Show More
6) Primordial Black Holes After 50 Years: The Bright Side
This talk will overview the history of primordial black hole (PBH) research from the first papers around 50 years ago to the present time. I will first discuss their possible formation mechanisms, inc...Show More
7) Moire Systems as Quantum Simulators of Many Strongly Correlated System
We will review the beginning of experimental and theoretical studies of moire systems and their evolution up to present. We will show how thousands of p orbitals in a moire unit cell of graphene can ...Show More
8) What String Theory Teaches Us About Scattering amplitudes
In this talk, I will explore the fascinating connections between string theory and quantum field theory, focusing on what we have learned from studying string scattering amplitudes. These insights hav...Show More
9) Microscopic Bounds on Macroscopic Theories
I will discuss Effective Field Theories that can originate from microscopic unitary theories, and their relation to moment theory. I will show that massive gravity, theories with isolated massive high...Show More
10) Gravity as a Quantum Computer
Our search for a quantum theory of gravity is aided by a unique and perplexing feature of the classical theory: General Relativity already knows" about its own quantum states (the entropy of a black ...Show More
