Lawler, Kim & Davis reveal mysteries of the pseudogap

Michael Lawler, Eun-Ah Kim and Seamus Davis close in on the secret recipe for high-temperature superconductors. Their year-long research into the pseudogap transition to superconductors is published in the current issue of Science.

Details in the Chronicle article, from Brookhaven National Lab, and in the May 9 issue of Science.

Cornell superconductivity research highlighted in Quanta Magazine

The April 30, 2014 Quanta Magazine feature article highlights inter-related efforts among researchers at the leading edge of high-temperature superconductivity. The Cornell research team of Eun-Ah Kim, Michael Lawler, and J.C. Séamus Davis play a key role in advancing theoretical models and developing methods to directly observe superconductors on the atomic scale.

Michelle Wang's group pioneers new method for studing multiple molecules at once

Michelle Wang and her lab have developed a new optical trap that allows them to study multiple molecules at once. Previous studies had used such traps to look at single molecules, such as DNA. This new device, called a nanophotonic standing wave array trap (nSWAT), can potentially trap hundreds of molecules at once. This allows researchers to complete experiments in a few days that used to take months.

Kyle Shen discovers atomic-scale switch in metal oxides

Kyle Shen and a team from Cornell and Brookhaven National Lab have discovered a new property of metal oxides that can act like a switch. Using a unique laboratory setup that allows for precision growth and measurement of the materials, the group discovered that varying how thick the layers of atoms are can determine whether the material acts as a metal or an insulator. This has exciting potential applications in atomic-scale electronics and superconductivity.

David Mermin says QBism puts the scientist back into science

A new understanding of quantum mechanics restores the balance between scientists and the objects they study, says David Mermin, the Horace White professor of physics emeritus, in this article in Nature.

“They call their new point of view ‘QBism’: Q is for quantum and B is for Bayesian — a view of probability that includes an agent who makes bets and updates odds. QBism attributes the muddle at the foundations of quantum mechanics to our unacknowledged removal of the scientist from the science,” Mermin says.

Jane Wang derives physical law controlling the path of hungry Tiger Beetles

Prof Jane Wang has developed an explination for the path Tiger Beetles take as they chase their prey. What looks like a messy looping path can be defined by physical rules that affect the beetles motion.
