Prof Ofer Firstenberg's Lab at Weizmann Institute of Science Can individual photons behave like conventional particles, such as electrons and atoms? Can atoms behave like light? These are the manifestations pursued in the Light-vs.-Matter Lab headed by Ofer Firstenberg. The team studies how to form molecules or twist vortices out of only two or three photons, how atoms diffract and interfere, and how to store and retrieve light in atomic media. Their research lies at the intersection of quantum optics, atomic physics, and quantum computing. https://lnkd.in/dDsxYCCb

Imagine the impossible – scientists have harnessed the power of a #blackhole right here on Earth! They didn't create a real one (thank goodness!), but rather a simulation that mimics the properties of a black hole's #eventhorizon. This simulated black hole surprised researchers by emitting a mysterious glow, potentially resembling the theorized #Hawkingradiation. Due to bizarre #quantum effects, hawking radiation is thought to seep from the edges of a black hole. If confirmed, this lab-created effect could be a groundbreaking step towards finally uniting the conflicting worlds of general relativity (the physics of the very large) and quantum mechanics (the physics of the very small). Love this stuff! #spacethefinalfrontier https://lnkd.in/eacSx7KU

Our work is out in Physical Review Letters! Thanks to my collaborator Dario Cilluffo and Ulm University for having me there last February! A special thanks to Mohammad Mirhosseini and his group @ Caltech for inspiring discussions! Here's a summary: Chirality and Markovianity, two significant concepts in theoretical physics and open quantum systems, are deeply interconnected. In this study we reveal their relationship in waveguide quantum electrodynamics with 'giant' atoms (i.e., atoms coupled to a waveguide at multiple points). In this setup, tuning the complex phases of the couplings (chirality) of a giant atom, one can control the system's Markovianity. We show that there exists an optimal phase configuration where the giant atom undergoes spontaneous emission (Markovian), for any (even large) time delays. In turn, the effect showcased in our study shows that the defining feature of giant atoms is the non-local nature of their couplings, rather than their non-Markovian character.

"Understanding the nature of quantum objects' behaviors is the premise for a reasonable description of the quantum world. Depending on whether the interference can be produced or not, the quantum object is endowed with dual features of a wave and a particle, i.e., the so-called wave-particle duality (WPD), which are generally observed in the so-called mutually exclusive experimental arrangements in the sense of Bohr's complementarity principle. Theoretical physicist John Wheeler proposed the delayed-choice experiment in the 1980s, pointing out that the methods used to observe photons will ultimately determine whether their behavior is like particles or waves." #photons

Now MIT physicists have captured direct images of second sound for the first time. Led by Martin Zwierlein, a MIT-CQE member, the Thomas A Frank Professor of Physics, the team visualized second sound in a superfluid — a special state of matter that is created when a cloud of atoms is cooled to extremely low temperatures, at which point the atoms begin to flow like a completely friction-free fluid. In this superfluid state, theorists have predicted that heat should also flow like a wave, though scientists had not been able to directly observe the phenomenon until now. The new results, reported today in the journal Science (https://lnkd.in/eNWAjuD9), will help physicists get a more complete picture of how heat moves through superfluids and other related materials, including superconductors and neutron stars. “It’s as if you had a tank of water and made one half nearly boiling,” a MIT-CQE member, Assistant Professor Richard Fletcher offers as analogy. “If you then watched, the water itself might look totally calm, but suddenly the other side is hot, and then the other side is hot, and the heat goes back and forth, while the water looks totally still.” Read more on MIT news: https://lnkd.in/e_SRyCBe #quantum #quantumcomputing #quantumphysics #quantumtechnology #quantumtechnologies #quantumtech #quantumcomputers #quantumcomputer #superconducting

Scientists are deepening our understanding of particle-duality in photons. This phenomenon, where photons can behave as both waves and particles, plays a crucial role in quantum mechanics. https://lnkd.in/dZu4FKqs #QuantumPhysics #PhotonDuality
