Here we propose and demonstrate two-dimensional electron–phonon coupling spectroscopy that can directly extract the electron–phonon coupling matrix elements for specific phonon modes and different electron energies. Using this technique, we measure the electron energy dependence of the electron–phonon coupling strength for individual phonon modes. It allows us to identify distinct signatures distinguishing non-local Su–Schrieffer–Heeger-type couplings from local Holstein-type couplings. Applying this methodology to a methylammonium lead iodide perovskite, we reveal particularly different properties, for example, temperature dependence or anisotropy, of the electron–phonon couplings of two pronounced phonon modes. Our approach provides insights into the microscopic origin of the electron–phonon coupling and has potential applications in phonon-mediated ultrafast control material properties.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"23 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143797746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, the prospect of controlling their properties has both fundamental and practical implications. However, in solid-state materials, it is often challenging to understand how quasiparticles are modified by external fields due to their complex interplay with other collective excitations. Here we demonstrate the manipulation of Fermi polarons—quasiparticles formed by impurities interacting with a Fermi gas—in a homogeneous atomic gas using fast radio-frequency control. Exploiting two internal states of the impurity species, we develop a steady-state spectroscopy, from which we extract the energy of the driven polaron. By varying the drive Rabi frequency, we measure the decay rate and the quasiparticle residue of the polaron in the weak-drive limit. At large Rabi frequencies, we observe signs that the drive causes a hybridization of the driven polaron with an incoherent background, leading to the breakdown of a description in terms of textbook quasiparticles. Our experiment establishes the driven Fermi polaron as a promising platform for studying controllable quasiparticles in strongly driven quantum matter and calls for a controlled theoretical framework to describe the dynamics of this strongly interacting quantum system.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"108 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-04-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143789755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

One explanation involves the competition between ferroelectricity and an instability characterized by the mesoscopic modulation of the polarization. These polarization density waves, which should intensify near the quantum critical point, break local inversion symmetry and are difficult to characterize with conventional X-ray scattering methods. Here we probe inversion symmetry breaking at finite momenta and visualize the instability of the polarization at the nanometre scale in SrTiO3 by combining a femtosecond X-ray free-electron laser with terahertz coherent control methods. We found polar-acoustic collective modes that are soft, particularly at the tens of nanometre scale.

A key remaining challenge is to enhance the capabilities of individual nodes, providing precise and robust control over multiple qubits. Here we demonstrate coherent control in a hybrid quantum node based on a diamond colour centre. We entangle three types of qubit: an electron spin as an interface qubit, a nuclear spin with long memory time and a flying photonic qubit. These qubits’ frequencies span three distinct regimes, from the optical to the radio-frequency domain. By incorporating two additional nuclear spins, we encode three memory qubits into a logical state using a repetition code and entangle this logical qubit with a photonic qubit. We repeatedly read out the error syndromes of memory qubits using the electron interface qubit, then apply real-time feedback operations to correct bit-flip errors. We perform our protocol for up to 12 rounds and demonstrate an improvement in the logical–photonic joint state population compared with its uncorrected counterpart. Our results demonstrate the feasibility of several key functionalities required for quantum repeaters to operate in full-fledged quantum networks.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"73 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-04-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143766903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Superconducting microwave qubits operating in cryogenic environments have emerged as promising candidates for quantum processor nodes. However, scaling these systems is challenging because they require bulky microwave components with high thermal loads that can quickly overwhelm the cooling power of a dilution refrigerator. Telecommunication frequency optical signals, however, can be fabricated in significantly smaller form factors to avoid challenges caused by high signal loss, noise sensitivity and thermal loads due to their high carrier frequency and propagation in silica optical fibres. Transduction of information by means of coherent links between optical and microwave frequencies is therefore critical to leverage the advantages of optics for superconducting microwave qubits, while also enabling superconducting processors to be linked with low-loss optical interconnects. Here, we demonstrate coherent optical control of a superconducting qubit. We achieve this by developing a microwave–optical quantum transducer that operates with up to 1.18% conversion efficiency with low added microwave noise, and we demonstrate optically driven Rabi oscillations in a superconducting qubit.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"20 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143758124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Zhang et al. Nature Physics https://doi.org/10.1038/s41567-024-02521-0 (2024)Casimir–Lifshitz forces have attracted much attention due to their relevance in controlling various phenomena1,2 and as a manifestation of quantum fluctuations3. Lifshitz and colleagues proposed a theory connecting the response function of materials to an electromagnetic field with the magnitude of these forces4. According to this theory, precise control over the permittivities of interacting materials allows both the magnitude and the sign of Casimir forces to be tuned, a phenomenon that has been experimentally demonstrated5,6. In principle, a similar tuning can be achieved by manipulating the permeabilities (μ) of the interacting materials at optical frequencies. However, this task becomes challenging when the contrast in permeability diminishes at much lower frequencies (approximately in the terahertz range)7. Zhang et al. reported the ability to tune Casimir forces using a magnetic field8. They demonstrated that the measured force between a gold sphere and a silica (SiO2) plate interacting through aqueous suspensions containing magnetite (Fe3O4) nanoparticles underwent a reversal—shifting from attraction to repulsion at a specific separation distance—when a magnetic field was applied. However, we argue that both their theoretical framework and experimental data fail to substantiate this claim.","PeriodicalId":19100,"journal":{"name":"Nature Physics","volume":"31 1","pages":""},"PeriodicalIF":19.6,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744692","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
