### Theoretical and Phenomenological Aspects of Top Quark Physics—Michal CZAKON

The year 2015 has marked the 20th anniversary of the discovery of the top-quark at the Tevatron proton-anti-proton collider at Fermilab near Chicago. The top-quark not only still is the ...

### Viral electrostatics—Rudolf PODGORNIK

I will present several models of the effects of electrostatic interactions on viruses. Starting from a discussion of charge distribution and the pertaining charge regulation description, I will explore in ...

### Prime Suspects and Coprime Accomplices; Quantum Tales in Number Theory—Giuseppe MUSSARDO

Number Theory is a subject full of curiosities, amusing problems and compelling challenges. The purpose of the seminar is to explore -- within the context of simple arguments -- the rich and ...

### The Universe as a hologram—Dario MARTELLI

String theory is the evolution of theoretical constructions developed during the past century, embracing and extending general relativity and quantum mechanics. One of the lessons of string theory has been ...

### News of the Standard Model Effective Field Theory: theory, tools and LHC strategy—Michael TROTT

With the discovery of a Higgs like scalar in 2012 at the LHC, and the lack of discovery of beyond the Standard Model states with masses proximate to the electroweak ...

### Is the Universe lop-sided?—Douglas SCOTT

Since the standard cosmological model is such a good fit to the cosmic microwave background anisotropy data, a great deal of attention has focused on any signs of "physics beyond ...

### Does Quantum Gravity constrain Large-Field Inflation?—Arthur HEBECKER

I will describe the theoretical interest in large-field inflation and its relation to potential future observations, e.g. through primordial gravitational waves. I will outline the possible fundamental obstructions to ...

### Studying galaxy formation with dynamical modelling—Michele CAPPELLARI

I introduce the key techniques used to model the dynamics of galaxies and illustrate how these method have contributed to our understanding of the mechanism by which galaxies form and ...

### Designing Rapid Phase Transitions and Shape-Shifting Materials Using Patterned Colloids—Ronald LARSON

The recent development of methods of conferring well-defined shape and interaction anisotropies to Brownian colloidal particles renders their phase behavior and dynamics closer to that of molecules, but on greatly ...

### Flavour Expedition to the Zeptouniverse—Andrzej BURAS

After the completion of the Standard Model (SM) through the Higgs discovery particle physicists are waiting for the discovery of new particles either directly with the help of the Large ...

### The Origin of Matter in the Universe—Tsutomu YANAGIDA

Paul Dirac proposed the baryon symmetric universe in 1933. This proposal has become very attractive now, since it seems that all pre-existing asymmetry would have been diluted if we had ...

### Scattering amplitudes: a bridge between modern mathematics and precision physics—Claude DUHR

*To be announced*

### Where high-energy physics and statistical mechanics meet—Christian MAES

In the past statistical physics and elementary particle physics have had many interesting interactions and various topics have been held in common. We have in mind studies of phase transitions ...

### Star Formation—Ralf KLESSEN

Stars and star clusters are the fundamental visible building blocks of galaxies at present days as well as in the early universe. They form by gravitational collapse in regions of ...

### Undecidability of the spectral gap—Toby CUBITT

The spectral gap - the difference in energy between the ground state and the first excited state - is of central importance to quantum many-body physics. It determines the phase diagram at ...

### Pseudo-observables in Higgs Physics—Gino ISIDORI

In view of future high-statistics data, it is useful to define a framework for precise determinations of the properties of the Higgs particle valid in generic extensions of the Standard ...

### Majorana fermions in superconductors: in search of the Zen particle—Carlo BEENAKKER

Among the many exotic properties of topological superconductors, the prediction that they can host Majorana fermions stands out both for its fundamental interest and for possible applications in topological quantum ...

### Probabilities and Signalling in Quantum Field Theory—Jeff FORSHAW

I will talk about a way to compute transition probabilities that works directly that the level of probabilities and not amplitudes. The formalism guarantees that the initial and final states ...
