Higgs Hour: 'Driven Active Nematics: External stresses drive topological transitions in spontaneously flowing fluids'Tyler SHENDRUK

While traditional fluids only flow when acted upon, a remarkable class of biomaterials spontaneously flow by means of their own internal energy. These “active fluids” comprise a wide range of biological systems that bridge between biological and condensed matter systems. This Brown Bag talk will focus on the example of ...

Higgs Hour with Sergey Koposov 'Hyper-velocity stars as probes of the super-massive black hole in the Galactic centre'Sergey KOPOSOV

Hyper-velocity stars are interesting objects that were first theoretically proposed by Richard Hills as products of interaction of a binary star and a supermassive black hole, that leads to the star being ejected out the galaxy with the speed of hundreds and thousands of km/s. About 15 years ago ...

Higgs Hour: 'Lattice calculations for high-precision tests of the Standard Model of Particle Physics'Vera GÜLPERS

The LHC has not yet found any significant deviation from the Standard Model at large energies and thus, indirect high-precision searches for signatures of physics beyond the Standard Model at low energies become more and more important. For any quantity involving the strong nuclear force, the only known approach for ...

Higgs Hour: 'Exploring the limits of magnetism in two-dimensional materials'Elton SANTOS

The family of 2D compounds has grown almost exponentially since the discovery of graphene and so too the rapid exploration of their vast range of electronic properties. Some family members include superconductors, Mott insulators with charge-density waves, semimetals with topological properties, and transition metal dichalcogenides with spin-valley coupling. Among several ...

Higgs Hour: 'Small stellar systems, big astrophysical questions'Anna Lisa VARRI

The blooming era of ‘precision astrometry’ for Galactic studies opened by Gaia and the revolutionary beginnings of ‘gravitational wave astronomy’ enabled by LIGO truly bring the rich internal dynamics of collisional stellar systems to the centre stage. But the current interpretative picture of the role of ‘small scales’ in the ...

Higgs Hour: 'Expanding the BAO science case'Florian BEUTLER

Cosmology has the potential to test fundamental physics through the discovery of new particles (e.g. dark matter) and new fields that governed the Universe's expansion at early times (inflation). One of the most powerful tools available for such studies is the Baryon Acoustic Oscillation (BAO) signal. Many future ...

Higgs Hour: 'Topologically Active Polymers'Davide MICHIELETTO

Polymer physics principles are increasingly acknowledged and applied to understand the behaviour of genome organisation and biopolymers in vivo. In spite of this they heavily rely on the assumption that polymers do not change topology (or architecture) in time, i.e. if they start as a linear chain of segments ...

Cosmology with radio and optical surveysAlkistis POURTSIDOU

I will describe how radio telescope arrays like MeerKAT and the Square Kilometre Array can kick off an exciting new era in cosmology using the innovative neutral hydrogen intensity mapping technique. I will also talk about the forthcoming Euclid satellite mission, concentrating on the theoretical modelling challenges we need to ...

Interference, Caustics and Oscillatory IntegralsJob FELDBRUGGE

Interference is one of the most universal phenomena in nature. In classical physics, the linear superposition of sound waves, surface waves, radio waves, light or gravitational waves all exhibit the same characteristic patterns of constructive and destructive interference. Interference is also fundamental to quantum physics, as exemplified by the Feynman ...

Strong field QED: probing fundamental physics with intense lasersAnton ILDERTON

I will give an overview of efforts to probe non-perturbative structures in QED using intense laser fields, beginning with an introduction to the Furry expansion of observables in strong backgrounds, which is the basis of most modern theory calculations in "strong field QED". I will then introduce the Ritus-Narozhny conjecture ...

From abstract matrix models to observations in the skySuddhasattwa BRAHMA

The BFSS matrix model is a proposed non-perturbative definition of M-theory in which space is emergent. In this talk, I shall present a new paradigm of early-universe cosmology in the context of the BFSS theory. Specifically, I will show that matrix theory leads to an emergent, non-singular cosmology which, at ...

Scattering amplitudes and inspiraling black holesMao ZENG

This will be a hybrid event with Mao presenting from the Higgs Centre. Future gravitational wave detectors require highly precise predictions for the waveforms from inspiraling black holes and neutron stars. We present advances in binary inspiral dynamics by taking classical limits of scattering amplitudes in perturbative quantum gravity. The ...
