Outline

Overview

Quantum statistical physics has revolutionized the world we live in - providing a profound understanding of the microscopic world and driving the technological revolution of the last few decades. Modern physics increasingly relies on solving equations using computational techniques, for modelling anything from the big bang to quantum dot lasers. The advanced unit covers the same overall concepts as PHYS3034 but with a greater level of challenge and academic rigour, largely in separate lectures. You will study techniques of quantum mechanics to predict the energy-level structure of electrons in atoms, introducing techniques useful in the broad field of quantum physics, with applications e. g. in atomic clocks. You will study the theoretical foundation of statistical mechanics, including both classical and quantum distributions. You will apply a variety of numerical schemes for solving ordinary and partial differential equations, learn about the suitability of particular methods to particular problems, and their accuracy and stability. The module includes computational lab sessions, in which you will actively solve a range of physics problems. In completing this unit you will gain understanding of the foundations of modern physics and develop skills that will enable you to numerically solve complex problems in physics and beyond.

Assessment summary

Assignments: There are four assignments in this unit, one per module and one larger problem assignment using aspects of both, quantum and statistical physics. You are encouraged to start early on the problem assignment as you will be able to solve aspects from it as early as it is released. Assignments are to be submitted through Canvas. Typewritten and handwritten assignments are acceptable – for handwritten assignment make sure the scans have good resolution and contrast and are not blurry or distorted. Only parts of the assignment that can readily be read on screen will be marked. Plan plenty of time for uploading your files ahead of the deadline to make room for connectivity issues, as deadlines will be enforced strictly. It is your responsibility to ensure that files have uploaded correctly with all pages.
Quizzes: There will be one statistical mechanics quiz, and 4 quantum physics quizzes. All quizzes will be online and last 15 minutes. You will have to do each quiz within a 24h window on the due date.
Computer Physics Practice Quizzes: Optional multiple choice quizzes are available under Canvas. These quizzes test your understanding of the lecture material and can be completed at any time. The quizzes are formative (weight is 0%).
Computational Physics Computer Labs: The laboratory sessions consist of sets of exercises requiring you to modify the codes introduced in the lectures (available via the Canvas site), and to write your own codes. The tasks involve implementing numerical methods and solving science problems. The laboratory sessions support the lecture material, and are a crucial part of the unit. The lab question sheets are available online as a Canvas quiz, and you may complete the lab at any time each week before the due date. Tutors will be available during the scheduled computer labs to assist you.
Final exam: The final exam will be a supervised, closed book exam on just the SM and QP sections of the course.
Final exam: If a second replacement exam is required, this exam may be delivered via an alternative assessment method, such as a viva voce (oral exam). The alternative assessment will meet the same learning outcomes as the original exam. The format of the alternative assessment will be determined by the unit coordinator

Assessment criteria

The University awards common result grades, set out in the Coursework Policy 2014 (Schedule 1).

As a general guide, a high distinction indicates work of an exceptional standard, a distinction a very high standard, a credit a good standard, and a pass an acceptable standard.

Result name	Mark range	Description
High distinction	85 - 100	A student demonstrates a flair for the subject and comprehensive knowledge and understanding of the unit material. A ‘High Distinction’ reflects exceptional achievement and is awarded to a student who demonstrates the ability to apply subject knowledge to novel situations.
Distinction	75 - 84	A student demonstrates an aptitude for the subject and a solid knowledge and understanding of the unit material. A ‘Distinction’ reflects excellent achievement and is awarded to a student who demonstrates an ability to apply the key ideas of the subject.
Credit	65 - 74	a student demonstrates a good command and knowledge of the unit material. A ‘Credit’ reflects solid achievement and is awarded to a student who has a broad understanding of the unit material but has not fully developed the ability to apply the key ideas of the subject.
Pass	50 - 64	At PS level, a student demonstrates proficiency in the unit material. A ‘Pass’ reflects satisfactory achievement and is awarded to a student who has threshold knowledge of the subject.
Fail	0 - 49	When you don’t meet the learning outcomes of the unit to a satisfactory standard.

Late submission

In accordance with University policy, these penalties apply when written work is submitted after 11:59pm on the due date:

Deduction of 5% of the maximum mark for each calendar day after the due date.
After ten calendar days late, a mark of zero will be awarded.

Academic integrity

The Current Student website provides information on academic integrity and the resources available to all students. The University expects students and staff to act ethically and honestly and will treat all allegations of academic integrity breaches seriously.

We use similarity detection software to detect potential instances of plagiarism or other forms of academic integrity breach. If such matches indicate evidence of plagiarism or other forms of academic integrity breaches, your teacher is required to report your work for further investigation.

You may only use artificial intelligence and writing assistance tools in assessment tasks if you are permitted to by your unit coordinator, and if you do use them, you must also acknowledge this in your work, either in a footnote or an acknowledgement section.

Studiosity is permitted for postgraduate units unless otherwise indicated by the unit coordinator. The use of this service must be acknowledged in your submission.

Learning support

Simple extensions

If you encounter a problem submitting your work on time, you may be able to apply for an extension of five calendar days through a simple extension.  The application process will be different depending on the type of assessment and extensions cannot be granted for some assessment types like exams.

Special consideration

If exceptional circumstances mean you can’t complete an assessment, you need consideration for a longer period of time, or if you have essential commitments which impact your performance in an assessment, you may be eligible for special consideration or special arrangements.

Special consideration applications will not be affected by a simple extension application.

Using AI responsibly

Co-created with students, AI in Education includes lots of helpful examples of how students use generative AI tools to support their learning. It explains how generative AI works, the different tools available and how to use them responsibly and productively.

Attendance and class requirements

There will be no practicals – only computer labs, which are well suited for online delivery. Students will now have a week to complete the computer labs. Instead of checkpoints students will fill out a canvas quiz (not timed).

Tutors will be available to help them during the scheduled computer lab hours (2 hours weekly).

Study commitment

Typically, there is a minimum expectation of 1.5-2 hours of student effort per week per credit point for units of study offered over a full semester. For a 6 credit point unit, this equates to roughly 120-150 hours of student effort in total.

Required readings
