- An introduction to Scientific Computing with Python
**Convenor:**Steven Bamford**Academic Year:**2017-18**Start Date:**23/10/2017**Module Code:**AS1**Module Name:**An introduction to Scientific Computing with Python**Duration (Hours):**1.5-2 hours**Duration (Weeks):**5 weeks, 1 session/week**Module Details:**This course will give a general introduction to Python programming, useful for all physics postgrads, but with an emphasis on astronomy. It is primarily aimed at graduate students requiring credits as part of the MPAGS training scheme, but other interested students and staff are welcome to join on request.A reasonable level of undergraduate programming experience is assumed.

The sessions will be timetabled soon. In previous years these have been distributed as one 1.5-2 hour session per week for five weeks in the Autumn semester. There are held in room A6 in the main Nottingham Physics building, and via Access Node broadcasts to various MPAGS and other institutions (Warwick, Birmingham, Bristol, Keele, Leicester, Loughborough, Southampton, ...)

The course will be formatively assessed by the development of a working Python program related to your studies.

- Astronomy Background Reading
**Convenor:**Simon Dye, Omar Almaini (Nottingham), Andrew Levan (Warwick), Alberto Sesana (Birmingham)**Academic Year:**2017-2018**Start Date:**10/10/2017**Module Code:**AS0**Module Name:**Astronomy Background Reading**Duration (Hours):**2 hours per week**Duration (Weeks):**October-June**Module Details:**The aim of this module is to broaden general knowledge in astronomy & astrophysics, and is designed to complement the more focussed background reading that students will naturally undertake in their own specialist area of research. This is a student-centred module, based around a list of reading topics that are tailored to each research group. Please contact your local convenor for further details.Students must summarize the material that they have learned in a log book, that must be reviewed and signed monthly by their supervisor. Students may maintain this log book as they see fit, but it should be sufficient to demonstrate that the required amount of time per week has been set aside to learn this material. It must be a hardback, bound volume; loose-leaf format will not be acceptable.

Assessment will be via an oral exam in the summer of the first year.

- Bose-Einstein Condensation in Ultra Cold Gases
**Convenor:**Dr Dimitri Gangardt**Academic Year:**2017-2018**Start Date:**10/17/2017**Module Code:**AT1**Module Name:**Bose-Einstein Condensation in Ultra Cold Gases**Duration (Hours):**10**Duration (Weeks):**5**Module Details:**After its theoretical prediction by Sateyndra N. Bose and Albert Einstein in 1925 the phenomenon of Bose -Einstein condensation (BEC) and related phenomenon of Superfluidity was crucial for understanding behaviour of various physical systems, from liquid helium to neutron stars. Its direct experimental observation with ultra cold alkali gases in 1995 leads to impressive growth of experimental and theoretical studies due to unprecedental level of tunability and control achieved with these systems. In this lecture course I will discuss theoretical concepts of BEC and long range order, elementary excitations, quantised vortices and their relation to phenomenon of superfluidity and macroscopic phase coherence of condensates. Where possible I will discuss experimental observation of these effects. I will also present recent developments of the field and discuss effects of strong correlations between ultra cold atoms arising in low dimensional systems and optical lattices. My presentation will be based on the standard theoretical tools of many body physics, such as first and second quantisation as well as path integrals.Learning objectives:

To understand and use in their own research the concepts outlined in the Syllabus (below). Completion of derivation presented in lectures will serve as exercises. A short individual interview with each student during Mid-term MPAGS Workshop will be used to assess students' progress.

Bibliography

The course will be based on the book "Bose Einstein Condensation" by Lev Pitaevskii and Sandro Stringari. Although the material in lectures is intended to be self contained, a basic knowledge of Quantum Mechanics and Statistical Physics will be required. The students are encouraged to use the corresponding Landau&Lifshits volumes (III,V and IX). Additional sources (such as articles and reviews) will be provided during the course.

- Classical and quantum phase transitions
**Convenor:**Stephen Powell (Nottingham)**Academic Year:**2017/18**Start Date:**11/7/2017**Module Code:**SM2**Module Name:**Classical and quantum phase transitions**Duration (Hours):**2 hours per week**Duration (Weeks):**5**Module Details:**A phase transition is a sudden qualitative change in the properties of a physical system when a parameter, such as temperature, is tuned through a critical value. In the vicinity of such transitions, remarkable behaviour can be observed, such as universality and (approximate) scale invariance. These critical phenomena can be understood using the "renormalization group", which relates a set of effective descriptions on a range of length scales, and also provides a framework for the calculation of physical observables.This module will give an introduction to phase transitions, critical phenomena, and the renormalization group, mainly in the context of classical and quantum spin models. It is intended mainly for students in condensed matter theory, but much of the material is relevant for other areas of theoretical physics.

Lectures:

Tuesdays and Wednesdays 10:00â€’11:00 from 7 November to 6 December (inclusive)

Topics:

Classical spin models; phase structures and critical properties

Landau theory of phase transitions; Ginzburg criterion

Euclidean field theory; diagrammatic expansion

Renormalization group; momentum-shell RG

Quantum phase transitions; quantum Ising chain

Assessment:

There will be two problem sets covering the material in the module.

- Epitaxy fundamentals
**Convenor:**Dr Maksym Myronov**Academic Year:**2017-2018**Start Date:**15/01/2018**Module Code:****Module Name:**Epitaxy fundamentals**Duration (Hours):**12, 1 hour per session**Duration (Weeks):**6 weeks, 2 hours per week**Module Details:**Most of modern electronic, optoelectronic, spintronic, thermoelectric, photovoltaic and sensor devices are fabricated of thin film semiconductor materials, which are epitaxially grown on a substrate. Due to precise control over chemical composition, doping, and dimensions of a thin film made possible by modern epitaxial techniques, one can obtain a material with entirely novel physical properties which are often based on quantum phenomena arising from the confinement of charge carriers in very tiny volumes, comparable with their De Broglie wavelengths. In order to understand epitaxial growth, relevant thermodynamic and kinetic processes and phenomena which make the transition from a disordered phase, i.e. gas or liquid, to an ordered crystalline phase possible have to be known.The proposed lecture course offers an introduction to the epitaxy fundamentals. Application examples of epilayers used in various existing and potentially new devices will accompany discussion and review on each topic. The course consists of 12 lectures provisional titles of which are outlined below.

1) Introduction

2) Thin films deposition

3) Epilayers characterization techniques

4) Substrates for epitaxy

- Formation of planetary systems
**Convenor:**Richard Alexander**Academic Year:**2017/18**Start Date:**02/11/2017**Module Code:**AS8**Module Name:**Formation of planetary systems**Duration (Hours):**2**Duration (Weeks):**5 weeks, 1 session per week**Module Details:**This module aims to give students a broad overview of how planets form. We will primarily consider planet formation from an astrophysical perspective (rather than a planetary science or cosmochemistry approach), and the course will cover both observational and theoretical research into planets and their origins. We will review observations of both the Solar System and exoplanets, and discuss observations and models of the structure and evolution of protoplanetary discs (which are the sites of planet formation). We will then consider the dynamics of solid bodies, and discuss how sub-micron-sized dust grains grow to form larger bodies. From this point our theory of planet formation remains incomplete, but we will discuss and critique the leading models for both terrestrial and giant planet formation. Finally we will discuss planet migration and the dynamics of young planetary systems, and how these processes shape the architectures of planetary systems.-----------
