Low-Frequency Noise in Quasi-1D (TaSe)I Weyl Semimetal Nanoribbons
Subhajit Ghosh, Fariborz Kargar, Nick R. Sesing +5
We report on low-frequency current fluctuations, i.e. electronic noise, in quasi-one-dimensional (TaSe)I Weyl semimetal nanoribbons. It was found that the noise spectral de…
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…
Combinatorial proof of the log-convexity for the derangements in the Coxeter groups
Hiranya Kishore Dey, Subhajit Ghosh
We provide the combinatorial proofs of the log-convexity for the derangement numbers in the symmetric group , hyperoctahedral group , and the demihy…
Coexistence of Magnetic Orders in Two-Dimensional Magnet CrI
Ben Niu, Tang Su, Brian A. Francisco +12
The magnetic properties in two-dimensional van der Waals materials depend sensitively on structure. CrI3, as an example, has been recently demonstrated to exhibit distinct magnetic…
Phonon and Thermal Properties of Quasi-Two-Dimensional FePS3 and MnPS3 Antiferromagnetic Semiconductor Materials
Fariborz Kargar, Ece Aytan, Subhajit Ghosh +9
We report results of investigation of the phonon and thermal properties of the exfoliated films of layered single crystals of antiferromagnetic FePS3 and MnPS3 semiconductors. The…
Dark Neutrino interactions phase out the Hubble tension
Subhajit Ghosh, Rishi Khatri, Tuhin S. Roy
New interactions of neutrinos can stop them from free streaming even after the weak interaction freeze-out. This results in a phase shift in the cosmic microwave background (CMB) a…
Total variation cutoff for the flip-transpose top with random shuffle
Subhajit Ghosh
We consider a random walk on the hyperoctahedral group generated by the signed permutations of the forms and for . We call this the flip-trans…
Tensors for tending to tensions in decays
Amol Dighe, Subhajit Ghosh, Girish Kumar +1
We propose a manifestly gauge invariant effective tensor operator that can account for the asymmetry anomaly in decays, contrary to the claim made in literature. Additi…
Clockworked VEVs and Neutrino Mass
Avik Banerjee, Subhajit Ghosh, Tirtha Sankar Ray
In this paper we present an augmented version of the Abelian scalar clockwork model to generate geometrically suppressed vacuum expectation values (vev) of the pseudo Nambu-Goldsto…
Total variation cutoff for the transpose top- with random shuffle
Subhajit Ghosh
In this paper, we investigate the properties of a random walk on the alternating group generated by -cycles of the form and . We call this the trans…
Dark neutrino interactions make gravitational waves blue
Subhajit Ghosh, Rishi Khatri, Tuhin S. Roy
New interactions of neutrinos can stop them from free streaming in the early Universe even after the weak decoupling epoch. This results in the enhancement of the primordial gravit…
