The Noise of the Charge Density Waves in NbSe Nanowires -- Contributions of Electrons and Quantum Condensate
Subhajit Ghosh, Sergey Rumyantsev, Alexander A. Balandin
Low-frequency electronic noise in charge-density-wave van der Waals materials has been an important characteristic, providing information about the material quality, phase transiti…
Phonon States in NbTe and TaTe Quasi-One-Dimensional van der Waals Crystals
Zahra Ebrahim Nataj, Fariborz Kargar, Sergiy Krylyuk +7
We report the results of polarization-dependent Raman spectroscopy of phonon states in single-crystalline quasi-one-dimensional NbTe and TaTe van der Waals materials. The m…
Temperature Dependent Low-Frequency Noise Characteristics of NiO/GaO p-n Heterojunction Diodes
Subhajit Ghosh, Dinusha Herath Mudiyanselage, Fariborz Kargar +3
We report on the temperature dependence of the low-frequency electronic noise in NiO/GaO p-n heterojunction diodes. The noise spectral density is of the 1/f-type near r…
Challenges in Interpreting the NANOGrav 15-Year Data Set as Early Universe Gravitational Waves Produced by ALP Induced Instability
Michael Geller, Subhajit Ghosh, Sida Lu +1
In this paper, we study a possible early universe source for the recent observation of a stochastic gravitational wave background at the NANOGrav pulsar timing array. The source is…
On the number of components of random polynomial lemniscates
Subhajit Ghosh
A lemniscate of a complex polynomial of degree is a sublevel set of its modulus, i.e., of the form for some In general, the nu…
Low-Frequency Electronic Noise in the Aluminum Gallium Oxide Schottky Barrier Diodes
Subhajit Ghosh, Dinusha Herath Mudiyanselage, Sergey Rumyantsev +5
We report on the low-frequency electronic noise in (AlGa)O Schottky barrier diodes. The noise spectral density reveals 1/f dependence, characteristic of the fli…
The magnificent ACT of flavor-specific neutrino self-interaction
Anirban Das, Subhajit Ghosh
We revisit the cosmology of neutrino self-interaction and use the latest cosmic microwave background data from the Atacama Cosmology Telescope (ACT) and the Planck experiment to co…
