A recently published paper in Nature Physics by a research group led by Jeremy Levy, distinguished professor of condensed matter physics at the University of Pittsburgh and founding director of the Pittsburgh Quantum Institute, describes how the Kronig-Penney model is reproduced within a programmable oxide material. The Kronig-Penney model, introduced in by Ralph Kronig and William Penney, shaped the understanding of semiconductors, metals and insulators—the materials that are used to create computers and many other technologies. The lead author, Megan Briggeman, used an atomic force microscope in a manner they describe as analogous to an Etch-A-Sketch toy, and created an artificial one-dimensional lattice of buckets for electrons that repeats every 10 nanometers. In real materials, the buckets are formed from individual atoms spaced from one another by a fraction of a nanometer. Briggeman found that electrons placed into this artificial lattice interact in unexpected ways, and in some sense behave as though the charge carriers were fractions of an electron. The experimentally observed behavior, partly explained by theory, extends far beyond the simple model of Kronig and Penney.

Meet and talk to specialist academics and admissions staff about postgraduate study in the UK and Europe. The MA in Peace and Conflict Studies is an exciting international and interdisciplinary two-year programme focusing on violent conflict as well as its prevention and management. You gain advanced knowledge in peace and conflict research, designed to help you understand the causes of violent conflict and to explain its effects and dynamics. As befits the complexity of violent conflict, the programme is interdisciplinary in nature, drawing on insights from politics and international relations, sociology and psychology. It examines the major theories and leading practices of conflict and conflict resolution, supplementing theory with detailed case studies. Topics typically covered within the programme include risk analysis, negotiation, mediation, conference diplomacy, twin-track diplomacy, third-party intervention, peace-keeping, peace-making, and coercive diplomacy.

The Bologna Process is a series of ministerial meetings and agreements between European countries to ensure comparability in the standards and quality of higher-education qualifications. It is named after the University of Bologna , where the Bologna declaration was signed by education ministers from 29 European countries in The process was opened to other countries in the European Cultural Convention  of the Council of Europe , and governmental meetings have been held in Prague , Berlin , Bergen , London , Leuven , Budapest - Vienna , Bucharest , Yerevan , Paris , and Rome Before the signing of the Bologna declaration, the Magna Charta Universitatum was issued at a meeting of university rectors celebrating the th anniversary of the University of Bologna and European universities in All member states of the EU are participating in the process, with the European Commission also a signatory.
