Observation of quantum droplets in a heteronuclear bosonic mixture [PDF]
Physical Review Research, 2019 We report on the formation of heteronuclear quantum droplets in an attractive bosonic mixture of ^{41}K and ^{87}Rb. We observe long-lived self-bound states, both in free space and in an optical waveguide.

Observation of the Quantum Boomerang Effect [PDF]
Physical Review X, 2022 A particle in an Anderson-localized system, if launched in any direction, should, on average, return to its starting point and stay there. Despite the central role played by Anderson localization in the modern understanding of condensed matter, this ...

Observation of quantum strong Mpemba effect [PDF]
Nature CommunicationsAn ancient and counterintuitive phenomenon known as the Mpemba effect (water can cool faster when initially heated up) showcases the critical role of initial conditions in relaxation processes.

Controlling heat and particle currents in nanodevices by quantum observation [PDF]
npj Quantum Materials, 2017 THERMOELECTRICS: Observe and control The presence of a quantum observer, acting locally in a thermoelectric nanodevice, is shown to be enough to change its heat and electronic transport path.

Observation and manipulation of quantum interference in a superconducting Kerr parametric oscillator [PDF]
Nature Communications, 2023 Quantum tunneling is the phenomenon that makes superconducting circuits “quantum”. Recently, there has been a renewed interest in using quantum tunneling in phase space of a Kerr parametric oscillator as a resource for quantum information processing ...

Observation of Superradiant Bursts in a Cascaded Quantum System [PDF]
Physical Review X, 2022 We experimentally investigate the collective radiative decay of a fully inverted ensemble of two-level atoms for a chiral, i.e., propagation direction-dependent light-matter coupling.

Observation of Quantum Droplets in a Strongly Dipolar Bose Gas [PDF]
Physical Review Letters, 2016 Quantum fluctuations are the origin of genuine quantum many-body effects, and can be neglected in classical mean-field phenomena. Here, we report on the observation of stable quantum droplets containing ∼800 atoms that are expected to collapse at the ...

Coherent terahertz magnon–phonon three-wave mixing in a layered antiferromagnet [PDF]
Nature CommunicationsThe coherent nonlinear dynamics between collective excitations, such as magnons and phonons, drive emergent phenomena in quantum materials, yet their direct observation remains limited.

Observation of the non-Hermitian skin effect and Fermi skin on a digital quantum computer [PDF]
Nature Communications, 2023 Lately, the non-Hermitian skin effect (NHSE) has been demonstrated in various classical metamaterials and even ultracold atomic arrays. Yet, its interplay with many-body dynamics have never been experimentally investigated.
