Quasi-deterministic Localization of Er Emitters in Thin Film TiO through Submicron-scale Crystalline Phase Control
Sean E. Sullivan, Jonghoon Ahn, Tao Zhou +5
With their shielded 4f orbitals, rare-earth ions (REIs) offer optical and electron spin transitions with good coherence properties even when embedded in a host crystal matrix, high…
Honeycomb-lattice Gamma model in a magnetic field: hidden Néel order and spin-flop transition
Zhongzheng Tian, Zhijie Fan, Preetha Saha +1
We show that a magnetic field in the high-symmetry direction lifts the macroscopic classical ground-state degeneracy of the honeycomb model and induces a long-range magnetic or…
The auto and cross angular power spectrum of the Cas A supernova remnant in radio and X-ray
Preetha Saha, Somnath Bharadwaj, Susmita Chakravorty +4
The shell type supernova remnant (SNR) Cas A exhibits structures at nearly all angular scales. Previous studies show the angular power spectrum of the radio emission t…
Angular power spectrum of supernova remnants: effects of structure, geometry and diffuse foreground
Samir Choudhuri, Preetha Saha, Nirupam Roy +2
The study of the intensity fluctuation power spectrum of individual supernova remnants (SNRs) can reveal the structures present at sub-pc scales, and also constrain the physical pr…
Machine learning dynamics of phase separation in correlated electron magnets
Puhan Zhang, Preetha Saha, Gia-Wei Chern
We demonstrate machine-learning enabled large-scale dynamical simulations of electronic phase separation in double-exchange system. This model, also known as the ferromagnetic Kond…
A study of Kepler supernova remnant: angular power spectrum estimation from radio frequency data
Preetha Saha, Somnath Bharadwaj, Nirupam Roy +2
Supernova remnants (SNRs) have a variety of overall morphology as well as rich structures over a wide range of scales. Quantitative study of these structures can potentially reveal…
Spin dynamics of the antiferromagnetic Heisenberg model on a kagome bilayer
Preetha Saha, Depei Zhang, Seung-Hun Lee +1
We study the spin dynamics of classical Heisenberg antiferromagnet with nearest neighbor interactions on a quasi-two-dimensional kagome bilayer. This geometrically frustrated latti…
On estimating the atomic hydrogen column density from the H I 21 cm emission spectra
Preetha Saha, Nirupam Roy, Mukul Bhattacharya
The 21 cm hyperfine transition of the atomic hydrogen (HI) in ground state is a powerful probe of the neutral gas content of the universe. This radio frequency transition has been…
Plaquette order in classical spin liquid stabilized by strong off-diagonal exchange
Preetha Saha, Zhijie Fan, Depei Zhang +1
We report a new classical spin liquid in which the collective flux degrees of freedom break the translation symmetry of the honeycomb lattice. This exotic phase exists in frustrate…
High spin polarization and the origin of unique ferromagnetic ground state in CuFeSb
Anshu Sirohi, Chandan K. Singh, Gohil S. Thakur +9
CuFeSb is isostructural to the ferro-pnictide and chalcogenide superconductors and it is one of the few materials in the family that are known to stabilize in a ferromagnetic groun…
