Applied Physics (CSIE) – II

Course Objectives:

• To provide a comprehensive understanding of physics concepts in computer science and engineering applications.

Magnetic Materials: Parameters, Ferromagnetic materials, Ferrites - Soft and Hard magnetic materials – GMR sensors - magnetic disk memories – Principle of magnetic recording – Magnetic data storage.

Activities: Determination of Hysteresis loop for ferromagnetic materials.

Logic Gates: Conversion of Binary to decimal - decimal to binary – binary coded decimal code-logic gates (OR, AND, NOT, NAND and NOR)–Exclusive OR gate- simplification based on basic Boolean theorems (sum of products, product of sums expression)- simplification by Karnaugh Map method (don’t care conditions).

Activities: Virtual demonstration of Logic Gates.

Nano-Devices: Introduction – electron density in bulk material – size dependence of Fermi energy-quantum confinement – quantum structures: quantum wells, wires and dots – band gap of nanomaterials. Tunneling- Coulomb blockade - single electron transistor - resonant-tunneling diode- Carbon nanotubes: Properties and applications.

Activities: Virtual demonstration of single electron transistor

Quantum Computing: Quantum system for information processing - quantum states – classical bits – quantum bits or qubits – Bloch sphere -CNOT gate – Single and multiple qubits – quantum gates (Pauli – X, Y and Z Gates, Hadamard Gate, Phase gate - T gate

.CNOT Gate) – advantage of quantum computing over classical computing.

Activities: Virtual demonstration of quantum computing
