Ronika's discovery of unique dynamics arising from interplay of spectral and band topologies in open quantum systems just out in Communications Physics. Nice collaboration with Suraj Hegde (IISER-TVM) and Tobias Meng (TU Dresden) @_SSCU_IISc nature.com/articles/s4200…

Happy to share a work from my sabbatical at ETH Zurich. I found that the quantum metric serves as a signature of persistent spin helix states, which host long-lived spin textures. Preprint just out on the arXiv: arxiv.org/abs/2603.08009

Delighted to share that Ronika has been selected for the Distinguished Student Award by the American Physical Society and the Forum on International Physics! The award will help her to attend the 2026 APS Global Physics Summit. Many congratulations! engage.aps.org/fip/honors/pri…

@AfsarReja's predictions of exceptional points in topological insulator-ferromagnet junctions now posted on arXiv. He discovered the crucial role of hexagonal warping in their emergence: arxiv.org/abs/2601.07443

Akshay's paper on modulation of polarization in Janus sliding ferroelectrics now out in 2D Materials: iopscience.iop.org/article/10.108…

@AfsarReja and Arka have proposed electric field tunable quantum metric (a relatively unexplored component of the quantum geometric tensor) in few layer phosphorene. Preprint just out: arxiv.org/abs/2512.00914

Ronika and Arka have discovered a new member of the Hall effect family. Upon oblique incidence on tilted potential barriers, carriers pick up a transverse momentum, resulting in a "Refraction Hall Effect". A nice collaboration with Prof. Diptiman Sen arxiv.org/abs/2511.15337

Delighted to return to ETH Zurich for a sabbatical semester. Grateful to @NicolaSpaldin and @snsf_ch for their support. Looking forward to interesting science!

"What’s fascinating about biological problems is that they operate on multiple time scales," says Govardhan Reddy, Associate Professor in SSCU, IISc. His lab studies how riboswitches help bacteria survive. Read more about his work at: kernel.iisc.ac.in/disarming-bact… #IIScresearch
