Physics (PH-GY)

These guided studies courses in physics are supervised by faculty member. | Prerequisite: Graduate Physics advisor approval. Note: Course may be repeated for additional credit.

This project course in applied physics is supervised by a faculty member. A written project proposal and final report must be submitted to the department chair and the advisor, and may be extended to a thesis with the project advisor's recommendation. | Prerequisite: Advisor Approval

Independent research project performed under guidance of thesis advisor. Bound thesis volume and oral defense in presence of at least three faculty members. Continuous registration with total 9 credits required.

An original investigation in some branch of physics, which may serve as basis for the PhD degree, is performed under the direction of a member of the department. The number of research credits registered for each semester should realistically reflect the time devoted to research. | Prerequisites: Passing grade in RE-GY 9990 PhD Qualifying Exam, degree status and graduate advisers and research director’s consent.

This course covers limits to the ongoing miniaturization (Moore’s Law) of the successful silicon-device technology imposed by physical limitations of energy dissipation, quantum tunneling and discrete quantum electron states. Quantum physical concepts and elementary Schrodinger theory. Conductance quantum and magnetic flux quantum. Alternative physical concepts appropriate for devices of size scales of 1 to 10 nanometers, emphasizing role of power dissipation. Tunnel diode, resonant tunnel diode, electron wave transistor; spin valve, tunnel valve, magnetic disk and random access memory; single electron transistor, molecular crossbar latch, quantum cellular automata including molecular and magnetic realizations. Josephson junction and “rapid single flux quantum” computation. Photo- and x-ray lithographic patterning, electron beam patterning, scanning probe microscopes for observation and for fabrication; cantilever array as dense memory, use of carbon nanotubes and of DNA and related biological elements as building blocks and in self-assembly strategies. | Prerequisites: PH-UY 2023

This course explores limits to the performance of binary computers, traveling salesman and factorization problems, security of encryption. The concept of the quantum computer based on linear superposition of basis states. The information content of the qubit. Algorithmic improvements enabled in the hypothetical quantum computer. Isolated two-level quantum systems, the principle of linear superposition as well established. Coherence as a limit on quantum computer realization. Introduction of concepts underlying the present approaches to realizing qubits (singly and in interaction) based on physical systems. The systems in present consideration are based on light photons in fiber optic systems; electron charges in double well potentials, analogous to the hydrogen molecular ion; nuclear spins manipulated via the electron-nuclear spin interaction, and systems of ions such as Be and Cd which are trapped in linear arrays using methods of ultra-high vacuum, radiofrequency trapping and laser-based cooling and manipulation of atomic states. Summary and comparison of the several approaches. | Prerequisites: PH-UY 2023
