Collective Behavior of Intelligent Active Brownian Particles in the Presence of a Static Obstacle
Surya Narayan Sahoo, Arabinda Bera, Jiarul Midya
Using computer simulations, we investigate the collective behavior of two-dimensional active Brownian particles (ABPs) with excluded-volume interactions in the bulk and in the pres…
Numerical simulations of inflationary dynamics: slow roll and beyond
Siddharth S. Bhatt, Swagat S. Mishra, Soumen Basak +1
Numerical simulations of the inflationary dynamics are presented here for a single canonical scalar field minimally coupled to gravity. We spell out the basic equations governing t…
Unambiguous joint detection of spatially separated properties of a single photon in the two arms of an interferometer
Surya Narayan Sahoo, Sanchari Chakraborti, Som Kanjilal +3
The quantum superposition principle implies that a particle entering an interferometer evolves by simultaneously taking both arms. If a non-destructive, minimally-disturbing intera…
Comment on "Observing the "quantum Cheshire cat" effect with noninvasive weak measurement''
Surya Narayan Sahoo, Dipankar Home, Alex Matzkin +1
In a very recent work [arXiv:2004.07451], Kim et al claimed to have made the first genuine experimental observation of the Quantum Cheshire Cat effect. We dispute this claim on the…
Quantum State Interferography
Surya Narayan Sahoo, Sanchari Chakraborti, Arun K. Pati +1
Quantum State Tomography (QST) has been the traditional method for characterization of an unknown state. Recently, many direct measurement methods have been implemented to reconstr…
Single photon sources: ubiquitous tools in quantum information processing
Urbasi Sinha, Surya Narayan Sahoo, Ashutosh Singh +3
Quantum technologies are the next big revolution in information technologies, computing, communication security, sensing as well as metrology. What do you use to explore all these…
Quantum Berezinskii-Kosterltz-Thouless Transition for Topological Insulator
Ranjith Kumar R, Rahul S, Surya Narayan +1
We consider the interacting helical liquid system at the one-dimensional edge of a two-dimensional topological insulator, coupled to an external magnetic field and s-wave supercond…
Measuring average of non-Hermitian operator with weak value in a Mach-Zehnder interferometer
Gaurav Nirala, Surya Narayan Sahoo, Arun K Pati +1
Quantum theory allows direct measurement of the average of a non-Hermitian operator using the weak value of the positive semidefinite part of the non-Hermitian operator. Here, we e…
Measuring the deviation from the superposition principle in interference experiments
G. Rengaraj, U. Prathwiraj, Surya Narayan Sahoo +2
The Feynman Path Integral formalism has long been used for calculations of probability amplitudes. Over the last few years, it has been extensively used to theoretically demonstrat…
