The variation of orbitals in the intraband transitions provides an efficient channel to convert spin to orbital angular momentum with spin-orbit interaction. This mechanism dominates the Gilbert damping of Fe below room temperature. The theoretical prediction is confirmed by the ferromagnetic resonance experiment performed on single-crystal Fe(001) films. A significant thickness-dependent damping oscillation is found at low temperature induced by the quantum well states of the corresponding energy bands. Our findings not only explain the microscopic nature of the recently reported ultralow damping of Fe-based alloys but also help for the understanding of the transport and dissipation process of orbital currents. <jats:supplementary-material> <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement> <jats:copyright-year>2025</jats:copyright-year> </jats:permissions> </jats:supplementary-material>","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"38 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744855","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}

Thanks to their tunable-range interactions, they are promising building blocks for quantum simulators. Here, we study the dynamics of an atom-photon bound state emerging from coupling a frequency-tunable quantum emitter—a transmon-type superconducting circuit—to the band edge of a microwave metamaterial. Employing precise temporal control over the frequency detuning of the emitter from the band edge, we examine the transition from adiabatic to nonadiabatic behavior in the formation of the bound state and its melting into the propagating modes of the metamaterial. Moreover, we experimentally observe multimode emission from the bound state, triggered by a fast change of the emitter’s frequency. Our Letter offers insight into the dynamic preparation of APBS and provides a method to characterize their photonic content, with implications in quantum optics and quantum simulation. <jats:supplementary-material> <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement> <jats:copyright-year>2025</jats:copyright-year> </jats:permissions> </jats:supplementary-material>","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"280 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744861","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}

Selecting an interaction potential for which a LLPT occurs in the bulk liquid, we conduct simulations of supercooled water nanodroplets having between 1000 and 80000 molecules. We show that as the droplet size decreases, the Laplace pressure grows large enough to drive the droplets through the transition from the low-density to the high-density liquid phase, and that all droplets in this size range are large enough to have cores exhibiting the structure and properties of bulk water. To guide experiments, we estimate the range of values for the critical pressure of the LLPT in real water that can be observed using nanodroplets, and propose structural and dynamical measures by which the LLPT in nanodroplets can be detected. <jats:supplementary-material> <jats:copyright-statement>Published by the American Physical Society</jats:copyright-statement> <jats:copyright-year>2025</jats:copyright-year> </jats:permissions> </jats:supplementary-material>","PeriodicalId":20069,"journal":{"name":"Physical review letters","volume":"36 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744858","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}

We propose that the bulk carriers of this holographic timelike entanglement entropy are boundary-anchored extremal surfaces probing analytic continuation of holographic spacetimes into complex coordinates. This proposal not only provides a geometric interpretation of all the known cases obtained by direct analytic continuation of closed-form expressions of holographic entanglement entropy of a strip subregion but crucially also opens a window to study holographic timelike entanglement entropy in full generality. We initialize the investigation of complex extremal surfaces anchored on a timelike strip at the boundary of anti-de Sitter black branes.

The expectation that &lt;o:math xmlns:o=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"&gt;&lt;o:mi&gt;f&lt;/o:mi&gt;&lt;/o:math&gt; should furnish a hallmark of universal behavior contrasts with its sensible dependence on nonuniversal features. We show that both nonuniversal amplitudes and universal exponents of leading power law singularities in all large deviation functions are determined by the fact that, due to extensivity, &lt;q:math xmlns:q=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"&gt;&lt;q:mrow&gt;&lt;q:mi&gt;f&lt;/q:mi&gt;&lt;q:mo stretchy=\"false\"&gt;(&lt;/q:mo&gt;&lt;q:mi&gt;m&lt;/q:mi&gt;&lt;q:mo stretchy=\"false\"&gt;)&lt;/q:mo&gt;&lt;q:msub&gt;&lt;q:mrow&gt;&lt;q:mo&gt;∼&lt;/q:mo&gt;&lt;/q:mrow&gt;&lt;q:mrow&gt;&lt;q:mo stretchy=\"false\"&gt;|&lt;/q:mo&gt;&lt;q:mi&gt;m&lt;/q:mi&gt;&lt;q:mo stretchy=\"false\"&gt;|&lt;/q:mo&gt;&lt;q:mo&gt;≫&lt;/q:mo&gt;&lt;q:mn&gt;1&lt;/q:mn&gt;&lt;/q:mrow&gt;&lt;/q:msub&gt;&lt;q:mi&gt;exp&lt;/q:mi&gt;&lt;q:mo stretchy=\"false\"&gt;(&lt;/q:mo&gt;&lt;q:mo&gt;−&lt;/q:mo&gt;&lt;q:mi&gt;c&lt;/q:mi&gt;&lt;q:mo stretchy=\"false\"&gt;|&lt;/q:mo&gt;&lt;q:mi&gt;m&lt;/q:mi&gt;&lt;q:msup&gt;&lt;q:mrow&gt;&lt;q:mo stretchy=\"false\"&gt;|&lt;/q:mo&gt;&lt;/q:mrow&gt;&lt;q:mrow&gt;&lt;q:mi&gt;δ&lt;/q:mi&gt;&lt;q:mo&gt;+&lt;/q:mo&gt;&lt;q:mn&gt;1&lt;/q:mn&gt;&lt;/q:mrow&gt;&lt;/q:msup&gt;&lt;q:mo stretchy=\"false\"&gt;)&lt;/q:mo&gt;&lt;/q:mrow&gt;&lt;/q:math&gt;, with δ&lt;/ab:mi&gt;=&lt;/ab:mo&gt;y&lt;/ab:mi&gt;H&lt;/ab:mi&gt;&lt;/ab:msub&gt;/&lt;/ab:mo&gt;(&lt;/ab:mo&gt;d&lt;/ab:mi&gt;−&lt;/ab:mo&gt;y&lt;/ab:mi&gt;H&lt;/ab:mi&gt;&lt;/ab:msub&gt;)&lt;/ab:mo&gt;&lt;/ab:math&gt; and &lt;eb:math xmlns:eb=\"http://www.w3.org/1998/Math/MathML\" display=\"inline\"&gt;&lt;eb:mi&gt;c&lt;/eb:mi&gt;&lt;/eb:math&gt; a nonuniversal coefficient.
