A Match Made in Physics

Whether with people, particles or the forces of physics, love always finds a way.


Paul Dirac

Paul Adrien Maurice Dirac was an outstanding twentieth century theoretical physicist whose work was fundamental to the development of quantum mechanics and quantum electrodynamics.


Enrico Fermi

Enrico Fermi was a titan of twentieth-century physics.


Richard Feynman

Theoretical physicist Richard Phillips Feynman greatly simplified the way in which the interactions of particles could be described through his introduction of the diagrams that now bear his name (Feynman diagrams) and was a co-recipient of the Nobel Prize in Physics in 1965 for his reworking of quantum electrodynamics (QED).


Max Planck

In a career that lasted seven decades, Max Planck achieved an enduring legacy with groundbreaking discoveries involving the relationship between heat and energy, but he is most remembered as the founder of the "quantum theory."


Switchable Transmission of Quantum Hall Edge States in Bilayer Graphene

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.

Exchange Bias Between Coexisting Antiferromagnetic and Spin-Glass Orders

A pane of window glass and a piece of quartz are both are transparent to light, but their atomic structure is very different. Quartz is crystalline at the atomic level while window glass is amorphous. This can also occur with magnetism at the atomic level in solids containing magnetic states such as antiferromagnetism (ordered) and spin-glass (disorded). This work describes the interaction (exchange bias) between ordered and disordered magnetic states and how the magnetic properties of the material are altered as a result.

Phase Diagram of URu2–xFexSi2 in High Magnetic Fields

Scientists used high magnetic fields and low temperatures to study crystals of URu2–xFexSi2. Using these conditions, they explored an intriguing state of matter called the "hidden order phase" that exhibits emergent behavior. Emergent behavior occurs when the whole is greater than the sum of its parts, meaning the whole has exciting properties that its parts do not possess; it is an important concept in philosophy, the brain and theories of life. This data provide strict constraints on theories of emergent behavior.


Spontaneous "Valley Magnetization" in an Atomically-Thin Semiconductor

Interactions between electrons underpin some of the most interesting – and useful -- effects in materials science and condensed-matter physics. This work demonstrates that, in the new family of so-called "monolayer semiconductors" that are only one atomic layer thick, electron-electron interactions can lead to the sudden and spontaneous formation of a magnetized state, analogous to the appearance of magnetism in conventional materials like iron.

A new class of correlated quasiparticle states discovered in a multi-valley semiconductor using optical absorption measurements in pulsed magnetic fields. This new type of multi-particle state results when excitons interact simultaneously with multiple electron reservoirs that are quantum-mechanically distinguishable by virtue of having different spin and/or valley quantum numbers.
