Generative Language Model for Catalyst Discovery [PDF]

Discovery of novel and promising materials is a critical challenge in the field of chemistry and material science, traditionally approached through methodologies ranging from trial-and-error to machine learning-driven inverse design. Recent studies suggest that transformer-based language models can be utilized as material generative models to expand ...

Universal and complete extraction for energy-invariant catalysis in quantum batteries versus no uncorrelated state-invariant catalysis [PDF]

arXiv
We investigate the role of catalysts in energy extraction from quantum batteries. Two basic classes of catalysts are proposed in this regard, viz., energy- and state-invariant catalysts. Moreover, we separately consider cases when the catalysts are or are not correlated with the battery, in the final output.

The Existence of Quantum Entanglement Catalysts [PDF]

IEEE. Trans. Inform. Theory, Vol. 51, No. 1, January 2005, 2003
Without additional resources, it is often impossible to transform one entangled quantum state into another with local quantum operations and classical communication. Jonathan and Plenio [Phys. Rev. Lett. 83, 3566(1999)] presented an interesting example showing that the presence of another state, called a catalyst, enables such a transformation without ...

Teleportation with Embezzling Catalysts [PDF]

arXiv
Quantum teleportation is the process of transferring quantum information using classical communication and pre-shared entanglement. This process can benefit from the use of catalysts, which are ancillary entangled states that can enhance teleportation without being consumed.

Communication with Quantum Catalysts [PDF]

arXiv
Communication is essential for advancing science and technology. Quantum communication, in particular, benefits from the use of catalysts. During the communication process, these catalysts enhance performance while remaining unchanged. Although chemical catalysts that undergo deactivation typically perform worse than those that remain unaffected ...

A Comparative study of catalytic activity and lifetime of novel micro-meso porous catalysts in MTO process [PDF]

arXiv, 2017
Recently, two kinds of mesoporous catalysts with high propylene selectivity in propane dehydrogenation (PDH) process has been successfully synthesized. The first proposed catalyst is SAPO-34 molecular sieve with hierarchical tuned nanostructure. The second catalyst is a novel bi-phase SAPO-34/ZSM-5 zeolite hierarchical composite utilized with TPA-SAPO ...

Many-body quantum catalysts for transforming between phases of matter [PDF]

arXiv
A catalyst is a substance that enables otherwise impossible transformations between states of a system, without being consumed in the process. In this work, we apply the notion of catalysts to many-body quantum physics. In particular, we construct catalysts that enable transformations between different symmetry-protected topological (SPT) phases of ...

Communicating catalysts

Nature Chemistry, 2018
The beauty and activity of enzymes inspire chemists to tailor new and better non-biological catalysts. Now, a study reveals that the active sites within heterogeneous catalysts actively cooperate in a fashion phenomenologically similar to, but mechanistically distinct, from enzymes.
