Notice Board
The Department of Physics was initiated in 1989 as a separate department. It was a result of several reorganizations of 'The Department of Physics and Mathematics' which was founded in 1926 along with the School of Mines. Excellence in research and teaching has always been a hallmark of the department.
The department currently has the following academic programs:
In addition to these programs, we regularly offer several core and elective physics courses to the engineering and science students from all the other Departments of the Institute. For more about the programs please follow the link for each program.
The department is actively involved in research across frontier areas of Physics that involve both fundamental and applied sciences including interdisciplinary avenues. We perform active research spanning the complexities of space and time, light-matter interactions, and the world of quantum information, interactions and materials.

The present study investigates the influence of hydrostatic pressure on the electronic structure and the electron–phonon coupling in Ba0.6K0.4BiO3 (BKBO) cubic superconductor using first-principles calculations. The increase in applied pressure increases the degree of orbital hybridization between Bi-s and O-p\sigma states. Also, suppression of oxygen hole is observed with increasing applied pressure, and Bi-s states play a more crucial role in the metallicity of the material. The study of lattice dynamics reveals that the cubic BKBO compound is dynamically stable up to an applied pressure of 7 GPa. The primary contribution to the overall electron–phonon coupling comes from the phonons associated with the oxygen bond stretching vibrations. With the increase in the hydrostatic pressure applied on the system, the phonon frequencies corresponding to oxygen bond stretching vibrations increase, leading to a decrease in electron–phonon coupling strength and, hence, the reduction in the superconducting Tc. The suppression of Tc can be attributed to the suppression of electronic density of states at the Fermi level. The superconducting parameters calculated using density functional theory within the generalized gradient approximation are underestimated compared to the experimental values. The implementation of the HSE06 hybrid functional enhances the electron–phonon coupling in the compound by incorporating the long-range Coulomb interaction in the system. It makes \lambda and Tc close to the experiments while maintaining the similar behavior of these superconducting properties under pressure as in the GGA calculations. These results highlight the exact role of nonlocal electronic correlation in the superconductivity in bismuthate.

In this work, the R-matrix method was employed to calculate the total and partial-channel photoionization cross-sections for the initial three bands of hydrogen sulfide, four bands of carbon disulfide, and three bands of carbonyl sulfide molecules. These calculations were performed over the entire range of photon energy, starting from the ionization thresholds of the respective states and extending significantly beyond the final level thresholds of the target ions. The present computations incorporate electron correlation effects and resonant photoionization contributions that have not been considered in any previously published literature. Intense absorption is observed in the total photoionization cross-section at energies below 20 eV, with a significant portion of it being caused by the excitation of molecules that subsequently decay by strong autoionization. The current R-matrix results are mostly in line with previous experimental measurements and theoretical calculations. The computed data are crucial for modeling parameters observed in photoionized plasmas.

Understanding the complete light-spin interactions in magnetic systems is the key to manipulating the magnetization using optical means at ultrafast timescales. The selective addressing of spins by THz electromagnetic fields via Zeeman torque is one of the most successful ultrafast means of controlling magnetic excitations. Here it is showed that this traditional Zeeman torque on the spins is not sufficient, rather an additional relativistic field-derivative torque is essential to realize the observed magnetization dynamics. This is accomplished by exploring the ultrafast nonlinear magnetization dynamics of rare-earth, Bi-doped iron garnet when excited by two co-propagating THz pulses. First, by exciting the sample with an intense THz pulse and probing the magnetization dynamics using magneto-optical Faraday effect, the collective exchange resonance mode is found between rare-earth and transition metal sublattices at 0.48 THz. Further, the magnetization dynamics are explored via the THz time-domain spectroscopic means. It is found that the observed nonlinear trace of the magnetic response cannot be mapped to the magnetization precession induced by the Zeeman torque, while the Zeeman torque supplemented by an additional field-derivative torque follows the experimental evidences. This breakthrough enhances the comprehension of ultra-relativistic effects and paves the way toward novel technologies harnessing light-induced control over magnetic systems.

Baseline drift is a common problem associated with metal oxide semiconductor based gas sensors operating at room temperature. There have been theoretical approaches to eliminate the errors involved in the response and sensitivity calculations due to baseline drift of gas sensors. However, no such experimental strategy such as using novel oxide semiconductors and their composites with stable electrical resistance, has so far been developed. We have observed that room temperature volatile organic compound gas sensing properties of tungsten tri-oxide (WO3) nanocrystals can be significantly enhanced by compositing them with graphitic carbon nitride (g-C3N4). Improved performances characterized by increased responses and reduced baseline drifts have been observed for WO3/g-C3N4 nanocomposite based gas sensors. Tungsten tri-oxide (WO3) nanocrystals were synthesized by hydrothermal method. Similarly, graphitic carbon nitride (g-C3N4) was synthesized by thermal poly-condensation of melamine. WO3/g-C3N4 nanocomposite was obtained by grinding above powders in an agate mortar and pestle followed by sintering at 450 °C for 2 h. Volatile organic compound gas sensing properties of WO3/g-C3N4 nanocomposite based sensors were studied at room temperature. WO3/g-C3N4 nanocomposite showed better stability and higher response compared to pristine WO3. Very small baseline drift was observed with WO3/g-C3N4 nanocomposite based sensors during volatile organic compound (VOC) gas sensing. Response of WO3/g-C3N4 nanocomposite towards 636 ppm ethanol gas, for example, was more than 20 % higher than that of WO3. The response and baseline resistance drift were measured for WO3/g-C3N4 pellets having varying weight percentages of WO3 and g-C3N4. With an increase in g-C3N4 content, baseline drift and response decline due to an increase in sensor material resistance. Selectivity of the sensor was examined by using three target gases: acetone, ethanol and formaldehyde. 50%WO3/50%g-C3N4 (w/w) nanocomposite showed 91 % response to 1272 ppm ethanol gas whereas the limit of detection for ethanol gas was 106 ppm. Innovation points of this work includes enhanced sensitivity, very small baseline drift and stable room temperature operation of WO3/g-C3N4 nanocomposite based ethanol gas sensors. Enhanced ethanol sensing properties of WO3/g-C3N4 nanocomposite at room temperature invite its possible application in commercial volatile organic compound gas sensors in future.
