Detection of actinides in CEMP-rs stars
A. M. Riyas, D. Karinkuzhi, S. Van Eck +4
The carbon-enhanced metal-poor stars with hybrid enrichments of slow- and rapid neutron-capture elements, the so-called CEMP-rs stars, still raise many questions due to their elusi…
Hyponormal block Toeplitz operators with finite rank self-commutators
Mankunikuzhiyil Abhinand, Raul E. Curto, Thankarajan Prasad
In this paper, we identify a large class of hyponormal block Toeplitz operators whose self-commutators are of finite rank. \ Recall that an operator is hyponormal and $[T_φ^{…
Subnormal block Toeplitz operators
Mankunikuzhiyil Abhinand, Raul E. Curto, In Sung Hwang +2
In this paper we consider the subnormality of block Toeplitz operators , where is an matrix-valued function on the unit circle of the form $$ Φ=QΦ^…
Tomogram-based quantifiers of nonclassicality dynamics in Kerr and cubic media
K. M. Athira, M. J. Neethu, M. Rohith
The reliable quantification of nonclassicality in quantum states under realistic decoherence remains a central challenge in advancing quantum technologies. Conventional quantifiers…
Characterizing quantum synchronization in the van der Pol oscillator via tomogram and photon correlation
Kingshuk Adhikary, K. M. Athira, M. Rohith
Scalable methods for detecting and quantifying the nonclassical nature of a quantum state in noisy environments are challenging due to a complex relationship between noise and quan…
Spectral nature of Sco X-1 observed using the X-ray SPECtroscopy and Timing (XSPECT) payload on-board XPoSat
V. P. Shyam Prakash, Vivek K. Agrawal, Rwitika Chatterjee +3
Scorpius X-1 is the brightest and first discovered X-ray source in the sky. Studying this source in the low-energy band has been challenging in the past due to its high brightness.…
