Can We Find the Emission Mechanism Behind the Extremely Bright GRB 230812B?
Utkarsh Pathak, Sameer K. Patil, Hitesh Tanenia +23
GRB 230812B is a bright long-duration GRB with a luminous, long-lived afterglow and an AstroSat/CZTI polarization measurement during the prompt phase, enabling a joint study of its…
Room-Temperature Electric-Field Control of Anomalous Hall Effect in Py/BTO/LSMO Heterostructures
Kusampal Yadav, Kousik Das, Aditya Raj +7
We demonstrate room temperature electric field control of the anomalous Hall effect in epitaxial Ni80Fe20 (Py) BaTiO3 (BTO) La0.7Sr0.3MnO3 (LSMO) thin film heterostructures grown o…
Quantum control of spin qubits using SOT-driven nanomagnets
Aniruddha Chakraborty, Kanishk Modi, Dhritiman Bhattacharya +3
Spin rotation (SR) is an essential capability for realization of single and two-qubit gates in spin quantum computing (SQC) architectures. To perform SR, resonant AC magnetic field…
ALD W-Doped SnO TFTs for Indium-Free BEOL Electronics
Mansi Anil Patil, Devarshi Dhoble, Shivaram Kubakaddi +4
This work reports back-end-of-line (BEOL) compatible, thin-film transistors (TFTs) with sub-10 nm tungsten-doped tin oxide (TWO) channels deposited by atomic layer deposition (ALD)…
Long GRB 250916A: an Off-axis Powerlaw Jet with Thermal Cocoon
Utkarsh Pathak, Sameer K. Patil, Hitesh Tanenia +22
Some gamma-ray bursts (GRBs) exhibit precursor emission episodes preceding the main emission, with a quiescent period in between. The properties of the precursor emission and the d…
Tunable Nanoparticle Stripe Patterns at Inclined Surfaces
Suman Bhattacharjee, Sanjoy Khawas, Sunita Srivastava
Periodic assemblies of nanoparticles are central to surface patterning, with applications in biosensing, energy conversion, and nanofabrication. Evaporation of colloidal droplets o…
