### New Horizons in Quantum Criticality—Andrew GREEN

The ideas of quantum criticality have proven a powerful unifying framework for a broad range of strongly correlated quantum systems. Experimental probes with ever greater sensitivity have resolved subtle new ...

### Rotation and Convection in the Sun—Steven BALBUS

Helioseismology techniques have revealed the details of the Sun's internal rotation with remarkable precision. The radiative zone is nearly uniformly rotating, whereas the convective zone differential rotation is generally ...

### The Copenhagen Interpretation Born Again —Tim HOLLOWOOD

An approach to the Copenhagen interpretation of quantum mechanics is developed which makes the Heisenberg cut between the deterministic microscopic quantum world and the stochastic macroscopic world explicit. The stochastic ...

### The Higgs Enigma & Maximally Natural Supersymmetry—John MARCH-RUSSELL

The discovery of an apparently elementary Standard-Model-like Higgs boson strengthens the deep mystery surrounding physics at the TeV energy scale. Almost all theories of the origin of the Higgs and ...

### Complex flows of complex fluids—Suzanne FIELDING

After a pedagogical introduction to the rheology (deformation and flow properties) of complex fluids and soft materials, we discuss recent research concerning viscoelastic instabilities in these materials, where an initially ...

### "That's the story": an interview with Roy Glauber—José LATORRE

We will show a documentary featuring an interview with Roy Glauber. Nobel laureate Prof. Roy J. Glauber is the last living scientist from the Theory Division of the Manhattan Project ...

### Quantum Origin of the Universe Structure—Viatcheslav MUKHANOV

I will explain how galaxies and their clusters could originate from the initial quantum fluctuations and then discuss the recent CMB experiments which confirmed the predictions of the quantum theory ...

### The knotted strands of life—Enzo ORLANDINI

Knots are part of our everyday life. In some cases they can be very useful as in climbing or sailing whereas in some others they can be a nuisance, as ...

### Gravitational redshifts in cosmology—Nick KAISER

Wojtak, Hansen and Hjorth (Nature, 2011) have measured the long- predicted gravitational redshifts in galaxy clusters using Sloan Digital Sky Survey data. The effect is very small, corresponding to a ...

### Statistical mechanics of quantum complex networks—Ginestra BIANCONI

The field of complex networks has been flourishing in the last fifteen years and has shed light on the underlying structure of complex systems as different as the Internet, or ...

### The Challenge of Galaxy Formation—Joseph SILK

The origin of the galaxies represents an important focus of current cosmological research, both observational and theoretical. Its resolution involves a comprehensive understanding of star formation, galaxy dynamics, supermassive black ...

### The International Linear Collider Higgs Factory—Philip BURROWS

An international team has recently completed the Technical Design Report for the International Linear Collider (ILC). The ILC is an electron-positron collider with a design target centre-of-mass energy of 500 ...

### Watching a Little Gas Cloud on its Way into the Galactic Supermassive Black Hole—Andreas BURKERT

The Galactic center is one of the most fascinating and extreme places in the Galaxy. Harboring a supermassive black hole with a mass of order 4 million solar masses it ...

### Fast-mode elimination in stochastic metapopulation models—Alan MCKANE

I will discuss an investigation into the stochastic dynamics of entities which are confined to a set of islands, between which they migrate. They are assumed to be one of ...

### BICEP2 and inflationary gravitational waves—Andrew LIDDLE

The BICEP2 collaboration recently announced detection of polarization patterns in the cosmic microwave background characteristic of primordial gravitational waves. This talk will describe the context and main results from BICEP2 ...

### The Sounds of Broken Symmetry in Superfluid Helium—Jim SAULS

The concepts of 'spontaneous symmetry breaking', 'generalized rigidity', and 'collective modes' play an important role in theoretical physics. Indeed much of the phenomenology of condensed matter can be understood in ...

### Old and New Results from the CMB—Andrew JAFFE

In the first part of this colloquium, I will assume that you've all seen quite a few talks on the recent Planck results, and so concentrate on some of ...

### Entanglement—José LATORRE

Entanglement is arguably the essence of Quantum Mechanics. It characterizes quantum correlation in states of condensed matter and quantum field theories. It provides the resources for quantum communication in the ...

### Heavy Flavour Physics at the Large Hadron Collider—Ulrik EGEDE

The analysis of rare decays of heavy flavour mesons has the potential to cast light on some of the big unknowns about the Universe such as: which underlying theory is ...

### What Is A Particle? Bernd Schroers' inaugural lecture—Bernd SCHROERS

About the Lecture This is a talk about the smallest units of matter. The atomic hypothesis - that all matter is made of indecomposable particles - has dominated thinking about matter and ...
