Scalar, vector, and tensor perturbations on the Kerr spacetime are governed by equations that can be solved by separation of variables, but the same is not true in generic stationary and axisymmetric geometries. This ...

Chandrayaan-3 is an upcoming lunar mission of India aimed at soft-landing and carrying out first-ever in situ investigations at a high-latitude location on the Moon. Chandrayaan-3 consists of a propulsion module, a lander ...

Hydrazone photoswitching functionalities integrated with three different fluorophore units (perylene (PY-PH), tetraphenylethylene (TPE-PH) and triphenylamine (TPA-PH)) were synthesized and demonstrated fluorophore unit ...

We systematically explore the construction of Nielsen's circuit complexity to a non-Lorentzian field theory keeping in mind its connection with flat holography. We consider a 2d boundary field theory dual to 3d asymptotically ...

For a four-stroke asymmetrically driven quantum Otto engine with working medium modeled by a single qubit, we study the bounds on nonequilibrium fluctuations of work and heat. We find strict relations between the fluctuations ...

Recently, it has been argued in [1] that Jackiw-Teitelboim (JT) gravity can be naturally realized in the Karch-Randall braneworld in (2 + 1) dimensions. Using the 'complexity=volume' proposal, we studied this model and ...

Quantum Key Distribution (QKD) offers unconditional security in principle. Many QKD protocols have been proposed and demonstrated to ensure secure communication between two authenticated users. Continuous variable (CV) QKD ...

Lead-free halide perovskites have gained immense popularity in photovoltaic and energy harvesting applications because of their excellent optical and electrical attributes with minimal toxicity. We synthesized composite ...

Historically, infinity was long considered a vague concept-boundless, endless, larger than the largest-without any quantifiable mathematical foundation. This view changed in the 1800s through the pioneering work of Georg ...

Magnetic flux ropes (MFRs) play an important role in high-energetic events like solar flares and coronal mass ejections in the solar atmosphere. Importantly, solar observations suggest an association of some flaring events ...
