The Scottish Doctoral Training Centre in Condensed Matter Physics, known as the CM-DTC, is an EPSRC-funded Centre for Doctoral Training (CDT) addressing the broad field of Condensed Matter Physics (CMP). CMP is a core discipline that underpins many other areas of science, and is one of the Priority Areas for this CDT call. Renewal funding for the CM-DTC will allow five more annual cohorts of PhD students to be recruited, trained and released onto the market. They will be highly educated professionals with a knowledge of the field, in depth and in breadth, that will equip them for future leadership in a variety of academic and industrial careers. Condensed Matter Physics research impacts on many other fields of science including engineering, biophysics, photonics, chemistry, and materials science. It is a significant engine for innovation and drives new technologies. Recent examples include the use of liquid crystals for displays including flat-screen and 3D television, and the use of solid-state or polymeric LEDs for power-saving high-illumination lighting systems. Future examples may involve harnessing the potential of graphene (the worlds thinnest and strongest sheet-like material), or the creation of exotic low-temperature materials whose properties may enable the design of radically new types of (quantum) computer with which to solve some of the hardest problems of mathematics. The UKs continued ability to deliver transformative technologies of this character requires highly trained CMP researchers such as those the Centre will produce. The proposed training approach is built on a strong framework of taught lecture courses, with core components and a wide choice of electives. This spans the first two years so that PhD research begins alongside the coursework from the outset. It is complemented by hands-on training in areas such as computer-intensive physics and instrument building (including workshop skills and 3D printing). Some lecture courses are delivered in residential schools but most are videoconferenced live, using the well-established infrastructure of SUPA (the Scottish Universities Physics Alliance). Students meet face to face frequently, often for more than one day, at cohort-building events that emphasise teamwork in science, outreach, transferable skills and careers training. National demand for our graduates is demonstrated by the large number of companies and organisations who have chosen to be formally affiliated with our CDT as Industrial Associates. The range of sectors spanned by these Associates is notable. Some, such as e2v and Oxford Instruments, are scientific consultancies and manufacturers of scientific equipment, whom one would expect to be among our core stakeholders. Less obviously, the list also represents scientific publishers, software houses, companies small and large from the energy sector, large multinationals such as Solvay-Rhodia and Siemens, and finance and patent law firms. This demonstrates a key attraction of our graduates: their high levels of core skills, and a hands-on approach to problem solving. These impart a discipline-hopping ability which more focussed training for specific sectors can complement, but not replace. This breadth is prized by employers in a fast-changing environment where years of vocational training can sometimes be undermined very rapidly by unexpected innovation in an apparently unrelated sector. As the UK builds its technological future by funding new CDTs across a range of priority areas, it is vital to include some that focus on core discipline skills, specifically Condensed Matter Physics, rather than the interdisciplinary or semi-vocational training that features in many other CDTs. As well as complementing those important activities today, our highly trained PhD graduates will be equipped to lay the foundations for the research fields (and perhaps some of the industrial sectors) of tomorrow.

Following the Nobel Prize winning discovery that lasers can cool atoms to extremely low temperatures, where they can occupy a single quantum state, there has been a lot of research into potential applications. Laboratory experiments with cold atoms have shown a 1000 times improvement in inertial navigation accuracy and a 1000 times improvement in timing over conventional atomic clocks. For these breakthroughs to be exploited in real applications the laboratory experiments must be developed into practical devices that could be operated in a satellite, aircraft, ship or hospital The aim of the FreezeRay project is to develop a commercial “all-in-one” system for cooling atoms. This will be the core engine of a cold atom system and will consist of a compact sealed vacuum chamber and a highly stable laser source that will cool the atoms. The technical approach will draw on component technology such as lasers and amplifiers that have been developed for optical communications and are highly reliable with operating lifetime exceeding 25 years in harsh environments.

The isolation of single-atomic layer graphene has led to a surge of interest in other layered crystals with strong in-plane bonds and weak, van der Waals-like, interlayer coupling. A variety of two-dimensional (2D) crystals have been investigated, including large band gap insulators and semiconductors with smaller band gaps such as transition metal dichalcogenides. Interest in these systems is motivated partly by the need to combine them with graphene to create field effect transistors with high on-off switching ratios. More importantly, heterostructures made by stacking different 2D crystals on top of each other provide a platform for creating new artificial crystals with potential for discoveries and applications. The possibility of making van der Waals heterostructures has been demonstrated experimentally only for a few 2D crystals. However, some of the currently available 2D layers are unstable under ambient conditions, and those that are stable offer only limited functionalities, i.e. low carrier mobility, weak optical emission/absorption, band gaps that cannot be tuned, etc. In a recent series of pilot experiments, we have demonstrated that nanoflakes of the III-VI layer compound, InSe, with thickness between 5 and 20 nanometers, have a thickness-tuneable direct energy gap and a sufficiently high chemical stability to allow us to combine them with graphene and related layer compounds to make heterostructures with novel electrical and optical properties. The main goal of this project is to develop graphene-hybrid heterostructures based on this novel class of two-dimensional (2D) III-VI van der Waals crystals. This group of semiconductors will enrich the current library of 2D crystals by overcoming limitations of currently available 2D layers and by offering a versatile range of electronic and optical properties. From the growth and fabrication of new systems to the demonstration of prototype devices, including vertical tunnel transistors and optical-enhanced-microcavity LEDs, our project will provide a platform for scientific investigations and will contribute to the technology push required to create new routes to device miniaturization, fast-electronics, sensing and photonics. There is great potential for further growth of all these sectors as the fabrication of 2D systems improves and as new properties are discovered and implemented in functional devices.

Global warming resulting from the emission of greenhouse gases has received widespread attention with international action from governments and industries, including a number of collaborative programs, such as SET-Plan, and very recently the International Climate Change hold 2015 in Paris. Key European Commission roadmaps towards 2030 and 2050 have identified Carbon Capture and Storage (CCS) as a central low-carbon technology to achieve the EUs 2050 Greenhouse Gas (GHG) emission reduction objectives, although there still remains a great deal to be done in terms of embedding CCS in future policy frameworks. The selective capture and storage of CO2 at low cost in an energy-efficient is a world-wide challenge. One of the most promising technologies for CO2 capture is adsorption using solid sorbents, with the most important advantage being the energy penalty reduction during capture and regeneration of the material compared to liquid absorption. The key objectives of GRAMOFON projects are: (i) to develop and protoype a new energy and cost-competitive dry separation process for post-combustion CO2 capture based on innovative hybrid porous solids Metal organic frameworks (MOFs) and Graphene Oxide nanostructures. (ii) to optimize the CO2 desorption process by means of Microwave Swing Desorption (MSD) and Joule effect, that will surpass the efficiency of the conventional heating procedures. This innovative concept will be set up by world key players expert in synthesis, adsorption, characterization and modelling, as well as process design and economic projections.

A combining arrangement comprises a power combiner having at least four ports. A first match-dependent oscillator is connected to input power at a first frequency to a first input port of the power combiner. A second match-dependent oscillator is connected to input power at a second frequency to a second input port of the power combiner. A mismatch is connected to a third port of the power combiner. The power combiner is operative to combine power from the first and second oscillators and, when the first and second frequencies are different, to apply a fraction of the combined power to the mismatch. The mismatch reflects at least some of the fraction of the combined power to the first and second oscillators to phase and frequency lock their outputs. A fourth output port of the power combiner is connected to receive the combined power. The power combiner attenuation is variable to adjust the proportion of the combined power split between the third port and fourth output port from 0% to 100% of the total combined power for any power values at the first input port and second input port.
