Margenau-Hill operator valued measures and joint measurability
Seeta Vasudevrao, H. S. Karthik, I. Reena +2
We employ the Margenau-Hill (MH) correspondence rule for associating classical functions with quantum operators to construct quasi-probability mass functions. Using this we obtain…
Canonical structures of and forms
Sudha, B. N. Karthik, A. R. Usha Devi +1
In their seminal paper (Phys. Rev.121, 920 (1961)) Sudarshan, Mathews and Rau investigated properties of the dynamical and maps acting on dimensional quantum systems. N…
Doping controlled Fano resonance in bilayer 1T-ReS: Raman experiments and first-principles theoretical analysis
Subhadip Das, Suchitra Prasad, Biswanath Chakraborty +6
In the bilayer ReS channel of a field-effect transistor (FET), we demonstrate using Raman spectroscopy that electron doping (n) results in softening of frequency and broade…
Chemical analysis of two extremely metal-poor stars HE 2148-2039 and HE 2155-2043
Meenakshi Purandardas, Aruna Goswami
We present elemental abundance results for HE 2148-2039 and HE 2155-2043 based on a detailed high-resolution spectroscopic analysis. The high-resolution SUBARU/HDS spectra used for…
Local sum uncertainty relations for angular momentum operators of bipartite permutation symmetric systems
I. Reena, H. S. Karthik, J. Prabhu Tej +3
We show that violation of variance based local sum uncertainty relation (LSUR) for angular momentum operators of a bipartite system, proposed by Hofmann and Takeuchi~[Phys.Rev.A {\…
Sum Uncertainty Relations: Uncertainty Regions for Qubits and Qutrits
Seeta Vasudevrao, I. Reena, Sudha +2
We investigate the notion of uncertainty region using the variance based sum uncertainty relation for qubits and qutrits.We compare uncertainty region of the qubit (a 2-level syste…
