Quantum-capacity bounds in spin-network communication channels

open access: yes, 2019
Using the Lieb-Robinson inequality and the continuity property of the quantum capacities in terms of the diamond norm, we derive an upper bound on the values that these capacities can attain in spin-network communication i.i.d.

Proton Decay and Fermion Masses in Supersymmetric SO(10) Model with Unified Higgs Sector

open access: yes, 2009
We make a detailed analysis on the proton decay in a supersymmetric SO(10) model proposed by K.Babu, I.Gogoladze, P.Nath, and R. Syed. We introduce quark mixing, and find that this model can generate fermion mass without breaking the experimental bound ...

Manufacturing-Driven Insights into Structure, Mechanics, and Permeability of Asymmetric LSCF Membranes via Freeze Casting and Tape Casting

open access: yesOpen Ceramics
The performance of dense membranes is influenced by both material properties and design features, with thinner membranes exhibiting faster transport rates than thicker ones. However, mechanical limitations restrict the use of standalone thin membranes. A
