**[Cr:4, Lc:0, Tt:0, Lb:12]**

This course is intended for Advanced MS
(Physics Major) students with an interest in gaining experience in an
experimental physics research group. The course can be offered every
semester, with a set of instructors drawn from the available
experimental research groups. The mode of instruction will comprise a
combination of lectures, tutorials and minor research projects to be
carried out in the research lab of the concerned instructor currently
the available modules are as follows out of which depending upon the
instructs at least two will be included in the course.

- NMR Spectroscopy Lab: Applying the Fourier transform to the NMR signal. Digital data processing, Nyquist theorem, Discrete Fourier transform, FFT algorithm, window functions and apodization. Physical basis of the NMR signal, phase correction, phase cycling. Redfield-Bloch relaxation theory and Master equation approach to identifying relaxation processes in systems of two and three coupled spins. The basic 2D FTNMR experiment and application to finding the structure of a biomolecule. Pulsed field gradients and understanding diffusion processes in polymer chains. Selective pulse rotations, composite pulses and implementation of an NMR Quantum Computing algorithm.
- Femtosecond Laser Lab: Experiments with cw laser, cavity stability, beam parameters, divergence, diameter, intracavity frequency doubling. Experiments with femtosecond laser: measurement of femtosecond laser parameters, pulse duration, autocorrelation, spectral width, repetition rate, beam diameter, divergence, application of fs pulses to measure speed of light in vacuum, air and in glass. Pump-probe spectroscopy, interferometric stability, ultrafast phenomenon measured by fs pump probe setup.
- Low Temperature Physics Lab: This lab will focus on low noise electronics. Projects will involve integrating different electronic equipments in one Labview programme. As an example varying gate voltage from a DAQ card output and measuring the conductance using a lock-in amplifier ( a mock device like a commercial JFET or MOSFET will be used). Students will also do some hands on Radio-frequency electronics like designing co-planar waveguides on a PCB . They will be expected to understand concepts like noise figures and noise temperatures, develop cryogenic amplifiers to be tested at liquid nitrogen temperatures.
- Solid State Physics Lab: Students will make new compounds by mixing up starting materials/chemicals. These could be superconducting, magnetic, or could show other interesting properties. Students will also do characterization and imaging of these and other materials using a Scanning Electron Microscope (SEM). Specifically students will look at gold nano-particles and the wonder material graphene using the SEM.
