Abstract : The principal Objective of the project was to exploit relativistic quantum manifestations of classical chaos in graphene and twodimensional Dirac fermion systems. Methods were developed to solve the Dirac equation in arbitrary domains. New phenomena uncovered include relativistic quantum scarring, chiral scars, chaos-based quantum control, and chaos-regularized relativistic quantum tunneling, etc. The AFOSR support helped create a new field of interdisciplinary research: Relativistic Quantum Chaos, which studies the relativistic quantum manifestations of classical chaos with applications with implications to the development of next generation of nanoscale electronic devices and circuits based on graphene and alternative two dimensional Dirac materials. The AFOSR project resulted in 20 refereed-journal papers, including papers in high-impact journals such as Physical Review Letters, and provided PI with the opportunity to supervise a number of PhD students: two graduated, one to graduate in 2016, and two ongoing. PI gave about a dozen plenary lectures, seminars, and colloquiums all over the world on relativistic quantum chaos.
