Our work on amorphous magnets has been published in Physical Review A as an editor suggestion 🎉 in this paper, we discuss how neutral atom quantum processing units can be used to explore the physics of such materials.

"Dark states are quantum states in which a system does not interact with external fields, such as light (i.e., photons) or electromagnetic fields. These states, which generally occur due to interferences between the pathways through which a system interacts with an external field, are undetectable using spectroscopic techniques. Researchers at Yonsei University in South Korea and other institutes recently discovered some undetectable condensed-matter dark states in palladium diselenide, a quantum system with two pairs of sublattices in its primitive cell." #quantumstates #darkstates

WE Quantum Graphene Physicists have observed a novel quantum effect termed “hybrid topology” in a crystalline material. This finding opens up a new range of possibilities for the development of efficient materials and technologies for next-generation quantum science and engineering. #aromaticgraphene #aromaticityandresonance #atroomtemperature #quantumchemistry #hybridtopology

Scientists led by Peter Zoller have developed a new tool for the measurement of entanglement in many-body systems and demonstrated it in experiments. The method enables the study of previously inaccessible physical phenomena and could contribute to a better understanding of #quantum #materials. The work has now been published in Nature. Entanglement is a quantum phenomenon where the properties of two or more particles become interconnected in such a way that one cannot assign a definite state to each individual particle anymore. Rather, we have to consider all particles at once that share a certain state. The entanglement of the particles ultimately determines the properties of a material.

This article on Phys org discusses a study on the tunable quantum anomalous Hall effects (QAHE) in van der Waals heterostructures, particularly focusing on materials composed of Bi and MnBi₂Te₄ monolayers. Researchers, using first-principles calculations, have demonstrated that by manipulating the magnetization orientation through strain, magnetic fields, or twisting, the magnetic and topological properties of these materials can be significantly altered. This tunability allows for the realization of QAHE with controllable Chern numbers, offering potential advancements in topotronic devices.

A New Dimension of Quantum Materials: Topological Phonons Discovered in Crystal Lattices https://lnkd.in/gjQmm_uD

"Research in quantum materials is paving the way for groundbreaking discoveries and is poised to drive technological advancements that will redefine the landscapes of industries like mining, energy, transportation, and medtech. A technique called time- and angle-resolved photoemission spectroscopy (TR-ARPES) has emerged as a powerful tool, allowing researchers to explore the equilibrium and dynamical properties of quantum materials via light-matter interaction. Published in Review of Modern Physics, a recent review paper by Professor Fabio Boschini from the Institut national de la recherche scientifique (INRS), along with colleagues Marta Zonno from Canadian Light Source (CLS) and Andrea Damascelli from UBC's Steward Blusson Quantum Matter Institute (QMI), illustrates that TR-ARPES has rapidly matured into a powerful technique over the last two decades." #quantummaterials

Phonons represent the collective vibrational patterns of atoms within a crystal structure and are crucial for several properties of solids, including thermal and electrical conductivity, and quantum states like superconductivity.

In our latest work out in Nature Physics, we show how an optical cavity can mediate strong, tunable and long-range interactions between nanoparticles levitated in vacuum. This brings us a step closer to observing quantum phenomena at macroscopic scales and building quantum-enhanced sensors. Congratulations and many thanks to the teams at ETH Zürich and Universität Innsbruck for this fruitful collaboration!

Wed, 7/24 at 5:30pm - Join Ali Yazdani from Princeton University for "Peering into the Secret Life of Electrons" Come at 5pm for tea and cookies. Learn more and RSVP here: https://lnkd.in/g5-tsSh8 Quantum physics is 99 years old. The quantum theory has been astonishingly successful, especially in describing the properties of individual quantum particles and light. This success has transformed our lives through the advances in technologies that we use every day. Currently, the frontier of quantum physics is understanding the collective properties of many interacting and entangled quantum particles. Many electron quantum phenomena are not only of fundamental interest but can lead to transformative technologies impacting the future — from new energy technologies to new computing platforms. In this talk, Dr. Yazdani will describe how certain materials host highly interacting electrons and how we use powerful quantum microscopy techniques to visualize their behavior. Part of the talk will focus on how we used these quantum microscopy techniques to crack a 90-year-old puzzle of electron behavior, by imaging for the first time a strange quantum crystal made up of only electrons. He will also describe how such experiments are forging a novel way to study the quantum fluids of interacting electrons in which new exotic quantum particles emerge. These exotic quantum particles are not only of fundamental interest but they might provide a new platform for creating quantum computing technologies. Ali Yazdani is the James S. McDonnell Distinguished University Professor of Physics at Princeton University and co-director of the Princeton Quantum Initiative. Yazdani is known for his research in advancing our understanding of emergent quantum phenomena by application and development of high-resolution microscopy techniques to directly visualize highly entangled quantum states of matter. #physics #electrons #particlephysics #princetonquantuminitiative #quantumphenomena #emergentphenomena #quantumphysics Ali Yazdani
