APPLY NOW for the 7th FQM Winter School!

QMC is hosting its 7th annual Fundamentals of Quantum Materials Winter School, to be held at the University of Maryland, January 15-19, 2024.  This school, (sponsored by the Gordon & Betty Moore Foundation, ICAM, and NSF), is aimed at providing fundamental training to our current and future generations of Quantum Materials scientists in synthesis and characterization techniques.  It will bring together senior and junior scientists to address topics at the forefront of current research into quantum materials, while also providing pedagogical background and practical training for junior scientists.  With an interdisciplinary and diverse crowd, including physicists, chemists, and materials scientists, participants will gain basic functional knowledge of how to plan and carry out synthesis relevant to the study of quantum materials and will have a unique opportunity to interact with some of the top researchers in the field while networking with fellow peers.  This year's school is focused on High Pressure Synthesis and Measurements, and will include a combination of  fundamental materials synthesis instruction as well as lectures on experimental techniques and practices from an impressive list of invited speakers. The school will be followed by a one-day Workshop focused on a current topic in quantum materials research, covering both experimental and theoretical work presented by a list of prominent scientists in the field. School students are expected to attend both events.  Applications can be submitted via web at https://fqm.physics.umd.edu

 

Podcast with Rick Greene on Room Temperature Superconductivity

False alarms sounded recently about the discovery of a room temperature superconductor by way of a material called LK-99. Since then, there has been a surge in interest in the topic: what exactly is a room temperature superconductor? How would one change our lives? And just how close are we to discovering one? Stay Tuned in Brief podcaster and former U.S. Attorney Preet Bharara speaks with physicist and superconductor expert Dr. Richard Greene of QMC. Podcast link

Pair Density Wave Mania!

Two QMC collaborations - with the Madhavan group at the University of Illinois-Urbana Champaign and the Davis group at Cornell University, University College Cork and Oxford University - have found striking instances of charge- and pair-density wave orders in the topological spin-triplet superconductor UTe2 using scanning tunneling microscopy techniques. The Madhavan group, who previously discovered chiral superconductivity in this material, unveiled an unusual kind of charge-density-wave order that is closely associated with superconductivity and is sensitive to magnetic fields. The Davis group used a superconducting Nb tip to identify the presence of three pair density waves along the same directions as the Urbana charge density waves.

Electrons Take New Shape Inside Unconventional Metal

Researchers in QMC, in collaboration with theorists at the Condensed Matter Theory Center (CMTC) and JQI, have produced the first experimental evidence that one metal—and likely others in its class—have electrons that manage to preserve a higher spin (j=3/2) angular momentum state in the topological half-Heusler semimetal YPtBi. A radical anisotropy observed in quantum oscillations in a highly isotropic system cannot be explained by conventional scenarios, but rather is naturally explained by the warping feature of the j=3/2 Fermi surface, providing direct proof of active high angular momentum quasiparticles that eventually superconduct.
