Methane Removal Using Zeolites: A Computational Analysis

Global warming is a pressing problem in the world today and it is exacerbated by the release of greenhouse gases, such as methane, into the atmosphere. Zeolites are being examined as a potential solution to the methane problem because they have a unique structure that can trap molecules. In particular, zeolites containing transitional metals show promise in oxidization reactions. Methane oxidation is an important reaction because it turns methane that contributes to global warming into methanol, a useable fuel source. In my project, I model zeolites containing different transitional metals using a software called SPARTAN and calculate their energies as a methane molecule passes through it. By looking at the energies of each zeolite, I can examine their stability and effectiveness relative to each other, helping determine which zeolites are better for atmospheric methane removal

Exclusion Principle for Quantum Dense Coding

We show that the classical capacity of quantum states, as quantified by its ability to perform dense coding, respects an exclusion principle, for arbitrary pure or mixed three-party states in any dimension. This states that no two bipartite states which are reduced states of a common tripartite quantum state can have simultaneous quantum advantage in dense coding. The exclusion principle is robust against noise. Such principle also holds for arbitrary number of parties. This exclusion principle is independent of the content and distribution of entanglement in the multipartite state. We also find a strict monogamy relation for multi-port classical capacities of multi-party quantum states in arbitrary dimensions. In the scenario of two senders and a single receiver, we show that if two of them wish to send classical information to a single receiver independently, then the corresponding dense coding capacities satisfy the monogamy relation, similar to the one for quantum correlations.Comment: v2: 6 pages, RevTeX 4, title changed, previous results unchanged, new results adde
