Activity 1

Topological matter: from gases to solids

(MA1) In this Major Activity we have two wide-ranging thrusts joining experiment-theory efforts to exploit the breadth of JQI. They combine atomic (neutral atoms and ions) and solid (hybrid semiconductor/superconductor devices and materials with ultra-strong spin-orbit coupling) systems, which are all candidate platforms for realizing new types of matter. Topological degrees of freedom in quantum systems are intrinsic many-body features that have remarkable properties such as extreme decoupling from environmental influences and robust quantum evolution even in the face of external noise. MA1 aims to develop a more complete understanding of the phases of topological matter, integrating AMO and CM approaches in both theory and experiment.

We attempt to (1) experimentally realize and theoretically understand the localized Majorana end-modes of 1D topological ordered systems; and (2) we will theoretically study topological systems that fall outside of the current classification scheme of noninteracting topological insulators, by including strong interactions or working with systems far from equilibrium.

Electrons tend to avoid one another as they go about their business carrying current. But certain devices, cooled to near zero temperature, can coax these loner particles out of their shells. In extreme cases, electrons will interact in unusual ways, causing strange quantum entities to emerge. At the Joint Quantum Institute (JQI), Jimmy Williams’ group is working to develop new circuitry that...

Researchers playing with a cloud of ultracold atoms uncovered behavior that bears a striking resemblance to the universe in microcosm. Their work, which forges new connections between atomic physics and the sudden expansion of the early universe, was published April 19 in Physical Review X and featured in Physics."From the atomic physics perspective, the experiment is...

In the latest experiment of its kind, researchers have captured the most compelling evidence to date that unusual particles lurk inside a special kind of superconductor. The result, which confirms theoretical predictions first made nearly a decade ago at the Joint Quantum Institute (JQI) and the University of Maryland (UMD), will be published in the April 5 issue of Nature. The...

Machine learning, the field that’s driving a revolution in artificial intelligence, has cemented its role in modern technology. Its tools and techniques have led to rapid improvements in everything from self-driving cars and speech recognition to the digital mastery of an ancient board game.Now, physicists are beginning to use machine learning tools to tackle a different kind of problem, one...

The 2015 discovery of a Weyl semimetal—and the Weyl fermions it harbored—provoked a flurry of activity from researchers around the globe. A quick glance at a recent physics journal or the online arXiv preprint server testifies to the topic’s popularity. The arXiv alone has had more than 200 papers on Weyl semimetals posted in 2016.Researchers at JQI and the Condensed Matter Theory Center (CMTC...

For decades, particle accelerators have grabbed headlines while smashing matter together at faster and faster speeds. But in recent years, alongside the progress in high-energy experiments, another realm of physics has been taking its own exciting strides forward.That realm, which researchers call condensed matter physics, studies chunks of matter moving decidedly slower than the protons in...

The swirling field of a magnet—rendered visible by a sprinkling of iron filings—emerges from the microscopic behavior of atoms and their electrons. In permanent magnets, neighboring atoms align and lock into place to create inseparable north and south poles. For other materials, magnetism can be induced by a field strong enough to coax atoms into alignment.In both cases, atoms are typically...

Particles can be classified as bosons or fermions. A defining characteristic of a boson is its ability to pile into a single quantum state with other bosons. Fermions are not allowed to do this. One broad impact of fermionic anti-social behavior is that it allows for carbon-based life forms, like us, to exist. If the universe were solely made from bosons, life would certainly not look like it...

From NIST-PML--JQI scientists have achieved a major milestone in simulating the dynamics of condensed-matter systems – such as the behavior of charged particles in semiconductors and other materials – through manipulation of carefully controlled quantum-mechanical models.

Going beyond their pioneering experiments in 2009 (the creation of “...

The quantum Hall effect, discovered in the early 1980s, is a phenomenon that was observed in a two-dimensional gas of electrons existing at the interface between two semiconductor layers. Subject to the severe criteria of very high material purity and very low temperatures, the electrons, when under the influence of a large magnetic field, will organize themselves into an ensemble state...

In quantum mechanics, symmetry describes more than just the patterns that matter takes — it is used to classify the nature of quantum states. These states can be entangled, exhibiting peculiar connections that cannot be explained without the use of quantum physics. For some entangled states, the symmetry of these connections can offer a kind of protection against disruptions. Physicists are...

Every electrical device is enabled by the movement of charge, or current. ‘Spintronics’ taps into a different electronic attribute, an intrinsic quantum property known as spin, and may yield devices that operate on the basis of spin-transport. JQI/CMTC theorists have been developing a model for what happens when spins are trapped in an optical lattice structure with a “double-valley” feature....
