This branch of physics has many practical applications and is currently producing many advances in fundamental physics.

Here is some of the research taking place at 亚洲情色.

The overarching goal of this research is the fundamental understanding of novel collective phases of matter, such as high-Tc superconductivity and quantum spin liquids, starting from microscopic principles and using modern analytical and computational quantum many-body methods.

Novel devices mimicking functionality of human neural systems – neuromorphic devices – is our hope to develop new technology allowing computer hardware to become as energy efficient as human brain when it comes to cognitive tasks of associative memory, recognition of visual images, words and features detection. Memristor is the fourth passive element in electric circuits in addition to three conventional ones (resistors, capacitors and inductors). Memristors change their resistance depending on electric pulse history. This allows, in principle, to fabricate artificial brains with artificial neurons linked via artificial synapses having an ability of learn and take actions based on information available.

Our group of researchers is working on modelling, fabrication, optimisation and testing of various neuromorphic memristor devices and artificial-neural networks based on different physical principles and computer architectures, in partnership with world-leading artificial intelligence companies and in collaboration with the Loughborough Departments of Chemistry and Computer Science, The University of Southampton, CNRS, Texas A&M University and other centres of neuromorphic research.

Fast electronic elements, such as semiconductor transistors, are key devices for many pivotal technologies from computing and communication to security, defence and medicine. Over the decades the speed of electronics has been growing dramatically and is now approaching the limit when conventional electronic elements are unable to progress further. To overcome this fundamental limit, we need to build devices based on the new physical principles. One of the research foci of the Department is the development of solid-state sub-THz and THz generators and detectors by utilising novel physical phenomena and materials.

Two-dimensional (2D) materials are extremely thin, often only a single atom thick, crystalline layers.鈥�疶hey can be created by reducing a bulk (3D) layered material (for example graphite) to its individual atomic layers (graphene) by repeated exfoliation, for example by using sticky tape!鈥�疶he properties of layered bulk materials are transformed and can exhibit exciting new physical phenomena when they are reduced to a single layer.鈥�疓raphene, the first 2D material to be isolated, is a single layer of carbon atoms with many exciting new properties.鈥�疐or example: it is one of the strongest materials but very flexible; electrons in graphene behave as if they have no mass and as if they are moving at the speed of light; and it is a better conductor of electricity than copper.鈥�疶he discovery of graphene’s potential led to the isolation and characterisation of many other 2D materials. Nearly 700 different types of 2D materials are predicted to exist each with very interesting properties for applications and now research in 2D materials graphene has attracted investment and research by many companies and universities around the world.

Here in the Physics department at Loughborough, our research activity on 2D materials is focused on understanding and developing their properties to create the next generation of novel magnetic, thermoelectric and electronic devices. We create new theories and models to understand how quantum physics can be used to control how electrical current flows through and between the layers of stacks of 2D materials. We investigate how interactions between electrons in these stacks can lead to new and exotic behaviour such as superconductivity at high temperatures. We are also fabricating and measuring heterostructures of 2D crystals for spintronic, thermoelectric and spin-caloritronic devices which take advantage of the intrinsic spin of electrons for low power, high frequency, logic and memory applications. We do our work in close collaboration with research groups across the world in the UK, US, Europe, Russia, China and Japan.

The rapid progress of electronics over the last hundred years – in particular with computing – has had a widespread impact on society. We have almost taken it for granted, that our phones and laptops will continue to have higher memory storage, work faster and have better battery life as we upgrade to the next version. Unfortunately, however, we are fast approaching a bottleneck in standard computing electronics: what is described as the end of ‘Moore’s Law’.

The area of spintronics (spin electronics) aims to utilise the quantum mechanical propertyies of an electron – its spin – to create functionalities and more efficiencies int devices that cannot be achieved by solely relying on the electron’s chargeelectronic devices for the next generation of computing. The discovery of spintronics was recognised by the 2007 Nobel Prize in Physics to Albert Fert and Peter Grunberg and have, over the last two decades, revolutionised data storage technology.

Our group of researchers isresearchers are working on nanospintronics, superconducting spintronics, and spin caloritronics, as welland spin caloritronics, as swith traditional thin films as well as with pin caloritronics, and the intersection of novel 2D and topological materials in this area. Our vision in this area is designing new types of functional materials and devices primary focus is on designing new types of devices for the generation and detection of spin currents, and establishing the condition under which these processes are energy efficient.
