Landauer\u27s Started as Partnership in Macon, Georgia
No full textImmigrants from Bavaria, Simon and Moritz Landauer entered the mercantile industry at Macon Georgia shortly after their arrival to the United States in 1852. During the Civil War, the men fled the South and established themselves on Main Street in Albion, Simon running a successful business that remained in operation into the 1980s.https://digitalcommons.brockport.edu/pioneer_record/1049/thumbnail.jp
Text Mining and the Information Content of Bank of Canada Communications
No full textThis paper uses Latent Semantic Analysis to extract information from Bank of Canada communication statements and investigates what type of information affects returns and volatility in short-term as well as long-term interest rate markets over the 2002-2008 period. Discussions about geopolitical risk and other external shocks, major domestic shocks (SARS and BSE), the balance of risks to the economic projection, and various forward looking statements are found to significantly affect market returns and volatility, especially for short-term markets. This effect is over and above that from the information contained in any policy interest rate surprise.Financial markets; Monetary policy implementation
The Landauer Principle: Re-Formulation of the Second Thermodynamics Law or a Step to Great Unification?
No full textThe Landauer principle quantifies the thermodynamic cost of the recording/erasure of one bit of information, as it was stated by its author: “information is physical” and it has an energy equivalent. In its narrow sense, the Landauer principle states that the erasure of one bit of information requires a minimum energy cost equal to kBT ln2, where T is the temperature of a thermal reservoir used in the process and k B is Boltzmann’s constant. The Landauer principle remains highly debatable. It has been argued that, since it is not independent of the second law of thermodynamics, it is either unnecessary or insufficient as an exorcism of Maxwell’s demon. On the other hand, the Landauer principle enables the “informational” reformulation of thermodynamic laws. Thus, the Landauer principle touches the deepest physical roots of thermodynamics. Authors are invited to contribute papers devoted to the meaning, interpretation, physical roots, experimental verification and applications of the Landauer principle. Papers devoted to the quantum and relativity aspects of the Landauer principle are encouraged
Quantum landauer erasure with a molecular nanomagnet
No full textThe erasure of a bit of information is an irreversible operation whose minimal entropy production of kB ln 2 is set by the Landauer limit1. This limit has been verified in a variety of classical systems, including particles in traps2,3 and nanomagnets4. Here, we extend it to the quantum realm by using a crystal of molecular nanomagnets as a quantum spin memory and showing that its erasure is still governed by the Landauer principle. In contrast to classical systems, maximal energy efficiency is achieved while preserving fast operation owing to its high-speed spin dynamics. The performance of our spin register in terms of energy-time cost is orders of magnitude better than existing memory devices to date. The result shows that thermodynamics sets a limit on the energy cost of certain quantum operations and illustrates a way to enhance classical computations by using a quantum system.Author correction: In the version of this Letter originally published, the key to the green and open circles in Fig. 4 was reversed; it should have shown that the green circles correspond to 'From χ versus T' and the open circles correspond to 'From χ versus H y '. This has now been corrected in all versions of the Letter. (Figure Presented). DOI: 10.1038/s41567-018-0140-xQN/van der Zant La
