DC Field Science Highlights
MagLab users have modified the critical current of Nb3SN, a material that was thought to be fully exploited, and boosted its performance by 50%.
The observation of topological states coupled with superconductivity represents an opportunity for scientists to manipulate nontrivial superconducting states via the spin-orbit interaction. While superconductivity has been extensively studied since its discovery in 1910, the advent of topological materials gives scientists a new avenue to explore quantum matter. BiPd is being studied using "MagLab-sized fields" by scientists from LSU in an effort to determine if it is indeed a topological superconductor.
Scientists revealed previously unobserved and unexpected FQH states in monolayer graphene that raise new questions regarding the interaction between electrons in these states.
Scientists found that the emergence of an exotic quantum mechanical phase in Ce1-xNdxCoIn5 is due to a shape change in the Fermi surface. This finding ran counter to theoretical arguments and has led investigators in new directions.
This work provides important insight into one of the parent materials of iron-based superconductors.
In the 14 years since its discovery, graphene has amazed scientists around the world with both the ground-breaking physics and technological potential it displays. Recently, scientists from Penn State University added to graphene's gallery of impressive scientific achievements and constructed a map that will aid future exploration of this material. This work is emblematic of the large number of university-based materials research efforts that use the MagLab to explore the frontiers of science.
Decades ago a mechanism was proposed that described a quantum phase transition to an insulating ground state from a semi-metal (excitonic insulator, or EI) using very similar mechanics to those found in the BCS description of superconductivity. The discovery of this transition to an EI in InAs/GaSb quantum wells is striking not only for the long-sought experimental realization of important physics, but also the presence of recently proposed topological behavior.
Researchers discover that Sr1-yMn1-zSb2 (y,z < 0.1) is a so-called Weyl material that holds great promise for building devices that require far less power.
This finding sheds light on the role of quasiparticle mass enhancement near a quantum critical point in one of the leading families of high-temperature superconductors.
New technique transforms common materials into powerful magnets.
Two independent research teams observed same behavior in double bilayer graphene.
The novel behavior could help scientists better understand the mechanisms behind high-temperature superconductivity.
At high magnetic field, free-flowing particles condense into “puddles.”
The work gives physicists a new tool for exploring and understanding a class of materials that could lead to faster electronics.
With a sufficiently high magnetic field, scientists can manipulate certain phase transitions in some molecules, a discovery that hints at future technological applications.
Discovery of a new kind of electron spin superstructure in crystals opens the tantalizing prospect of finding other emergent exotic phases.
Discovering previously unobserved quantum states nested inside the quantum Hall effect in a single-layer form of carbon known as graphene, researchers have found evidence of a new state of matter that challenges scientists' understanding of collective electron behavior.
Niobium diselenide is found to retain its superconductivity even under very high magnetic fields.
Just as all matter may exist in the three famous everyday phases — solid, liquid and gas — complex materials may exist in a combination of subtle phases not apparent to the eye. This finding shows that a class of materials, which all contain copper oxide and are known to exhibit a variety of subtle phases, may have even more complexity than thought. And, in fact, some phases are brought about not by changes in temperature but magnetic field.
Examining the material samarium hexaboride, scientists discover seemingly contradictory properties and an exciting, new mystery for physicists.
