New paper in Phys. Rev. Letters...with Zubin Jacob, Teri Odom, Alexandra Boltasseva and Hadiseh Alaeian The spatial distribution of interacting ensemble of emitters plays a crucial role in super- & sub-radiance, quantum sensing and energy transport. In this work we present a promising new avenue to manipulate the dimensionality using a nanophotonic media. https://lnkd.in/e4uG8TQ5

I am delighted to attend American Physical Society’s DAMOP 2024. #apsdamop I will present a poster on Tuesday in poster session I (D00.108, 4-6pm) and give a talk on Friday in the Fermi Hubbard session (Y08.00009, 12:06-12:18pm) about “Emergent Feshbach-like interactions in a doped Majumdar-Ghosh model”. We study spinon-holon bound states in a frustrated quantum magnet, which is experimentally feasible using ultracold polar molecules. Using matrix product states, we observe signatures of Fermi polaron-like branches in the ARPES spectrum signaling an emergent Feshbach-like resonance associated with the (un-)binding of the spinon and the holon. If you’re interested in discussing, approach me at the poster session, after my talk, or any time during the conference!

https://lnkd.in/g4rMJyDS https://lnkd.in/ggb26QTY Recent publication in collaboration with the Innsbruck experiment (Group of Prof Francesca Ferlaino with Dr Manfred Mark leading this work). We report on the measurement of excitations in a quantum droplet of magnetic erbium atom atoms. Our first theoretical work on the collective excitations of quantum droplets was about 7 years ago and it is wonderful to finally have some detailed measurements showing the curious behaviour.

📈 The Stokes' shift is the difference between absorbed and emitted fluorescent wavelength maxima. It was named after George Gabriel Stokes, an Irish physicist and mathematician, who published the paper explaining fluorescence in 1852. A long Stokes' shift means there is little overlap between the excitation wavelenth and emission wavelength. 🔴 Bangs Labs offers Europium chelate beads for clear results in your next #LateralFlowAssay.

Confine that photon! Researchers from The Institute of Photonic Sciences (ICFO) have introduced a type of polaritonic cavity that redefines the limits of light confinement. The work demonstrates an unconventional way of confining photons, overcoming traditional limits in nanophotonics. https://ow.ly/cnLu50QGTUz

Our paper on Fractional Quantum Anomalous Hall (FQAH) Phase for Raman Superarray of Rydberg Atoms is published! https://lnkd.in/gG9GTmRU https://lnkd.in/gM3JKYmv We implement Rydberg atoms with Raman-assisted dipole-dipole interactions to realize a bosonic FQAH phase. We also propose a novel quench protocol to probe the fractionalized excitations in OBC.

📝 New platforms for ultraconfined plasmons and optical coupling to external light Researchers at ICFO tackle the problem of light confinement in nanocavities from two different perspectives. First, they successfully realize high-quality ultrathin crystalline metal structures that can support spatially compressed plasmons; and second, they demonstrate an efficient technique to couple light to confined surface plasmons. The initial idea of ICREA Prof. at ICFO Javier García de Abajo and his group members Saad Abdullah, Eduardo J. C. Dias, Jan Krpenský and Vahagn Mkhitaryan materialized in a successful experiment, now published in ACS Photonics. In this study, they demonstrate a new method that couples light to flat surface plasmons more effectively than previous strategies. ICFO News 👉 https://bit.ly/3zlWiv1

Umbrella for Atoms ☂️ In a groundbreaking development, researchers at the Würzburg-Dresden Cluster of Excellence ct.qmat have engineered a protective film that shields quantum #semiconductor layers just one atom thick from environmental influences without compromising their revolutionary quantum properties. This puts the application of these delicate atomic layers in ultrathin electronic components within realistic reach. Further info ➡ https://lnkd.in/ep_fcPcN

🌟 Exciting Start to 2024! 🚀 Our Result of the Month for January 2024, thanks to the brilliant work by J. Reimann, K. Sumida, M. Kakoki et al. takes us into the intricate world of ultrafast population dynamics in the topological surface state of Sb2Te3. Conducted at Philipps-Universität in Germany, this groundbreaking research utilized time- and angle-resolved two-photon photoemission spectroscopy. Linearly polarized mid-infrared pump pulses enabled a direct optical excitation across the Dirac point, revealing a strongly enhanced resonant excitation within the Dirac cone along specific directions and resulting in a macroscopic photocurrent when aligned along a Γ–K direction. Their experimental approach allowed them to unravel the transiently excited population's decay and photocurrent through elastic and inelastic electron scattering within the full Dirac cone, providing unprecedented insights. Remarkably, the study demonstrates that doping Sb2Te3 with vanadium atoms significantly enhances inelastic electron scattering to lower energies while sparingly affecting elastic scattering around the Dirac cone. Kudos to this exceptional team for reshaping our understanding of ultrafast dynamics in topological surface states! 🧪⚡️ Read the full Result of the Month here: https://lnkd.in/dpbM_DE3 #ScientaOmicron #resultofthemonth #electronspectroscopy

📰 The possibility of phase transitions in magnetic #quantum spin models within a #wavefunction-only framework is explored, showing that #magnetization arises only when particles are indistinguishable and energy conservation limits macroscopic superpositions. The research uses probability theory and large deviation techniques to address these phenomena, offering insights into quantum thermodynamic ensembles. 👨🎓 Leonardo De Carlo, Leonardo De Carlo 📺 Full Video: https://lnkd.in/gKn6adqU 📰 This video is adapted from the paper: 10.3390/e25040564 published by Entropy MDPI #quantummagnetism #wavefunction #deviations
