Putting a crypto insider in charge of the Commodity Futures Trading Commission is like putting a drug lord in charge of the DEA.
Industry insiders shouldn’t be regulators, but this is even worse.
Crypto isn’t even a legitimate industry, just one good at playing the catch-me-if-you-can game with the regulators it’s about to own.

The Blockchain Association Just Bought the CFTC
The revolving door isn’t just corrupting the CFTC—it may end the pretense of a Commission altogether.

Exploring Topological Effects in Thin-Film X-Ray Cavities
Quantum control of single x-ray photons can be achieved using thin-film nanostructure cavities with embedded layers of resonant nuclei. Here, we design and theoretically investigate tailored cavity structures that implement a non-Hermitian version of the Su-Schrieffer-Heeger one-dimensional topological model. By tuning the geometry of the structure, different topological phases can be realized. We show that the presence of topological edge states can be identified in the reflectivity spectra of…

Last year, we bought a collection of 17 Georgia paintings by 19th- and 20th-century artists, many of whom are lesser known. Even the ones who are better known, like #NellChoateJones, aren't exactly _well_ known. We're excited to start studying these works and learning about the Georgia scenes many of them show.

Designing toroidal cavities for quantum computation
Toroidal microwave cavities are investigated for potential use in quantum information storage and computation. Since exact analytical results are not available for this geometry, extensive numerical simulation has been used to develop a universal phenomenological model ("spectral flow diagram"). This model is needed to guide the non-trivial design of toroidal resonators. A host of new modes that do not exist in cylindrical cavities are classified, including novel counter-intuitive ground states…

Parks gift shops directed to remove items that ‘disparage Americans’
Trump officials have directed staff at national parks to review all items in gift shops for anti-American content.
The move is part of the administration’s wider campaign to scrub federal institutions of “corrosive ideology” recognizing historical racism and sexism.

The directive instructs park staff to report by Friday any retail items that have content that “inappropriately disparages Americans past or…

Saturable nonlinearity induced quantum correlations in optomechanics
We propose a scheme that induces quantum correlations in optomtomechanical systems. Our benchmark system consists of two optically coupled optical cavities which interact with a common mechanical resonator. The optical cavities host saturable nonlinearity which triggers either gain or losses in each cavity. Without these nonlinearities, there are no quantum correlations, i.e., entanglement and steering, generated in the system. By turning on the nonlinearities, gain and losses are switched on, …
