Phonon modes and Raman signatures of MnBi2nTe3n+1 (n=1,2,3,4) magnetic topological heterostructures
Yujin Cho, Jin Ho Kang, Liangbo Liang +8
An intrinsic antiferromagnetic topological insulator can be realized by intercalating Mn-Te bilayer chain in a topological insulator, . $\m…
Free-streaming and Coupled Dark Radiation Isocurvature Perturbations: Constraints and Application to the Hubble Tension
Subhajit Ghosh, Soubhik Kumar, Yuhsin Tsai
Dark radiation (DR) appears as a new physics candidate in various scenarios beyond the Standard Model. While it is often assumed that perturbations in DR are adiabatic, they can ea…
Low-Frequency Electronic Noise Spectroscopy of Quasi-2D van der Waals Antiferromagnetic Semiconductors
Subhajit Ghosh, Fariborz Kargar, Amirmahdi Mohammadzadeh +2
We investigated low-frequency current fluctuations, i.e. noise, in the quasi-two-dimensional (2D) van der Waals antiferromagnetic semiconductor FePS3 with the electronic bandgap of…
Electrically-Insulating Flexible Films with Quasi-One-Dimensional van-der-Waals Fillers as Efficient Electromagnetic Shields
Zahra Barani, Fariborz Kargar, Yassamin Ghafouri +8
We report polymer composite films containing fillers comprised of quasi-one-dimensional (1D) van der Waals materials, specifically transition metal trichalcogenides containing 1D s…
Cutoff phenomenon for the warp-transpose top with random shuffle
Subhajit Ghosh
Let be a sequence of non-trivial finite groups. In this paper, we study the properties of a random walk on the complete monomial group generated b…
