Seeing Scrambled Spins

July 19, 2017

Two experimental groups have taken a step towards observing the “scrambling” of information that occurs as a many-body quantum system thermalizes.

Cost and Precision of Brownian Clocks

Biomolecular networks capable of counting time can be thought of as “Brownian clocks.” The energy budgets necessary to run two classes of such clocks, assuming some minimal required precision, are theoretically determined.

Stochastic and Macroscopic Thermodynamics of Strongly Coupled Systems

Thermodynamics describes how macroscopic systems exchange energy in the form of heat and work, yet many microscopic systems such as molecular motors exhibit behavior that seems to follow the same principles. A new theoretical framework for describing the thermodynamics of microscopic systems that interact strongly with their surroundings is presented.

Quantum and Information Thermodynamics: A Unifying Framework Based on Repeated Interactions

Nanomachines are subject to random thermal and quantum fluctuations that are not captured by traditional thermodynamic theory. A new theoretical investigation offers a step toward a unified nanoscale theory by showing how externally prepared systems (e.g., atoms in an optical cavity or DNA bases in an enzyme reaction) that interact with a nanoscopic device can be a source of nonequilbrium free energy.

Thermodynamics of Computational Copying in Biochemical Systems

Both computers and living cells copy information, but doing so comes at a cost of energy. A new theoretical analysis shows that biological systems come close to but do not reach the predicted lower bound on this energy, and that the cost increases as copying becomes more accurate.

Experiments in Stochastic Thermodynamics: Short History and Perspectives

Stochastic thermodynamics extends the traditional laws of thermodynamics to microscopic systems where thermal and quantum fluctuations cannot be ignored. This review summarizes progress in this field with a look at several experimental and theoretical results and a look toward potential applications in biology and nanotechnology.

Events

Physics Next Workshops
Thursday Aug. 24th, 2017 - Saturday Aug. 26th, 2017
Hyatt Place Long Island hotel, Long Island, NY

The American Physical Society is initiating a new series of international workshops. These Physics Next workshops will be aimed at fostering new and emerging areas of physics research, focusing on topics that straddle traditional subject boundaries and are starting to “emerge from the noise.”

The upcoming workshop is titled “Physics Next: From Quantum Fields to Condensed Matter,” and will take place on August 24 - 26, 2017. More information.

APS Cultivates ORCID Links
July 18, 2017

On July 18, 2017, APS, along with the Institute of Physics Publishing (IOPP), has taken an important step towards working more closely with the Open Researcher and Contributor ID (ORCID) system of unique identifiers by signing the ORCID open letter requiring the collection of ORCID iDs in their publishing processes.

APS Joins the Initiative for Open Citations (IO4C)
July 11, 2017

Starting on July 11, APS will begin participating in the Initiative for Open Citations (I4OC), a collaboration among scholarly publishers to make information freely available about what papers are cited by a given journal article. This information had always been available to those subscribing to the Physical Review journals, but now the citation data will be open to all.

Physical Review Materials’ First Issue
June 19, 2017

The first articles from Physical Review Materials (PRMaterials) are now available online and showcase the high-quality, broad-scope research in APS’s newest journal. All articles appearing in the first issue are free to read through 2017. PRMaterials provides a common publication and reference source to the expanding community of physicists, materials scientists, chemists, engineers, and researchers in related disciplines that carry out high-quality original research in materials.
