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 states of electronic
matter in the vicinity of quantum critical points. Attempts to understand
these have led to a remarkable ...

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 constant on cones, dominated by its latitudinal (not cylindrical)
gradient. In this talk, I will show how standard dynamics augmented ...

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 nature of
quantum mechanics arises when the system is probed by a set of coarsegrained
macroscopic observables whose resolution scale ...

The Higgs Enigma & Maximally Natural Supersymmetry—John MARCHRUSSELL
The discovery of an apparently elementary StandardModellike Higgs
boson strengthens the deep mystery surrounding physics at the TeV energy
scale. Almost all theories of the origin of the Higgs and the associated
scale of electroweak symmetry breaking either have dynamically unnatural
parameters, or severely lack explanatory power for most features ...

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 homogeneous flow field gives way to a spatially more complicated
one. We focus particularly on extensional flow protocols and present ...

"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 at Los Alamos. His clear, fluent and
articulate narration brings first hand information on the life at Los Alamos,
the ...

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 of cosmological perturbations.

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
we experience each time we try to disentangle extension cables or garden
pipes. Like extension cables, long biological filaments such ...

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 velocity shift of
only ~10 km/s in clusters with internal random motions ~600 km/s, but is in
good ...

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 protein interaction in the cell. This extensive body
of work has defined a new paradigm for looking at interacting ...

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 holes, and the cosmology of the very early
universe. It is a field that is largely driven by a phenomenology ...

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 electronpositron
collider with a design target centreofmass energy of 500 GeV. Following the
Higgs boson discovery it has been proposed to realise the ILC by building a
250 GeV 'Higgs ...

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 experiences cycles of activity and star formation, separated
by periods of quiescence that last of order a million years. The ...

Fastmode 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 two types, and in addition to migration, they also reproduce and
die. Systems which fall into this class are common ...

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 and
outline their significance in supporting and constraining cosmological models,
particularly the inflationary cosmology.

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 terms of these concepts within the framework of quantum mechanics and statistical mechanics. The story I tell is a synthesis ...

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 the
less wellknown results. In particular, I will concentrate on what Planck can
say about the very largescale structure 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 form of
teleportation and cryptography. It establishes the obstruction to classicaly
simulate quantum systems in an efficient way. It may ...

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 the Standard Model embedded in, what is the nature of
dark matter, and what is the process that created the ...

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 energy in modern physics, culminating
in today's Standard Model of particle physics. This model is one of the
triumphs ...
