While FSBS involving the fundamental optical mode and guided transverse acoustic waves has been studied in different optical fibers, its behavior in few‐mode fibers and the potential for tailoring the FSBS gain spectrum through optical wave distributions remain largely unexplored. Here, the first analysis of intra‐mode FSBS is presented in few‐mode optical fibers and demonstrate the possibility of harnessing its spectral profile using high‐order optical modes. Experimental results, supported by a theoretical analysis and full vectorial finite element method simulations, demonstrate that selecting specific optical modes in few‐mode optical fibers enhances overlap between high‐order acoustic modes and optical forces, significantly boosting the amplitude of high‐order acoustic resonances. This approach offers a practical and previously unexplored mechanism to manipulate FSBS photon‐phonon interactions, creating new opportunities for studying FSBS fundamentals and paving the way for developing novel optomechanical devices.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"5 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228546","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}

An emblematic example of this is the Mpemba effect, where an initially “hot” system cools faster than an initially “cooler” one. This effect has recently been studied in a variety of different classical and quantum settings. In this Letter, we find a novel signature of the Mpemba effect in the context of quantum batteries. We identify situations where batteries in higher charge states can discharge faster than less charged states. Specifically, we consider a quantum battery encoded in a single bosonic mode that is charged using unitary Gaussian operations. We show that the ergotropy, used here as a dynamical indicator of the energy stored in the battery, can be recast as a phase space relative entropy between the system’s state and the unitarily connected passive state, at each time. Our formalism allows us to compute the ergotropy analytically under dissipative dynamics and allows us to understand the conditions which give rise to a Mpemba effect. We also find situations where two batteries charged to the same value using different operations can discharge at different rates. <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":"17 1","pages":""},"PeriodicalIF":8.6,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228591","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}

In addition, the strong absorption of THz wave by water makes it difficult for THz metasurface sensor to achieve the direct detection of aqueous solution. In this paper, a novel sandwich-type THz metasurface microfluidic sensor with high sensitivity for direct detection of aqueous solution is proposed and verified. Numerical simulation results show the proposed sensor has a perfect absorption peak with high <jats:italic>Q</jats:italic>-factor of 67.55 and high <jats:italic>S</jats:italic> of 0.534 THz/RIU at 1.85 THz. The proposed sensor not only can confine all the energy in microfluidic channel greatly improving the energy utilization and light–matter interaction, but also precisely controls the liquid thickness at 3.1 μm greatly reducing the absorption of THz wave, which provides the foundation for realizing the direct detection of aqueous solutions with high sensitivity.

A key requirement for reliable measurement of broadband optical pulses is a sufficiently large phase-matching bandwidth. Monolayer two-dimensional material, such as transition metal dichalcogenide, with its exceptionally high second-order nonlinear susceptibility and the absence of phase-matching bandwidth limitations due to its atomic thickness, provides an ideal platform for broadband ultrashort pulse characterization. In this work, we present a noncollinear frequency-resolved optical gating technique utilizing monolayer MoS<sub>2</sub>, capable of characterizing ultrashort broadband pulses over an octave. The noncollinear second-harmonic generation configuration enables the autocorrelation signal, distinguishable by its unique spatial frequency, to be extracted with ease and without requiring additional optical adjustments or filters. Moreover, we experimentally demonstrate that this method can accurately measure dispersion-induced chirp distortions in pulses, as well as fully reconstruct the characteristics of complex and unknown pulses.","PeriodicalId":23,"journal":{"name":"ACS Photonics","volume":"20 1","pages":""},"PeriodicalIF":7.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228792","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}

This nontrivial phenomenon is discovered and experimentally observed in a synthetic two‐level photonic system, supported by a two‐polarization‐mixing process in a rotated electrically‐engineered photonic crystal. It is shown that the synthetic system undergoes a continuous evolution in the presence of a highly controllable change of magnetic field equivalent, but does not accumulate any GP until reaches its criticality condition, at which the GP exhibits a rapid transition from 0 to . The effect is interpreted by a topological discontinuity in the evolution trajectory of a photonic state, represented in parameter space. Since the GPT is highly sensitive to initial settings, it may trigger relevant applications in light shaping and photonic switching. The demonstrated transition effect is a general dynamical phenomenon of a physical wave. As such, it has profound implications to many different two‐level systems such as electronic waves, acoustic waves, and matter waves.","PeriodicalId":204,"journal":{"name":"Laser & Photonics Reviews","volume":"8 1","pages":""},"PeriodicalIF":11.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144228609","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}

By allowing coherent evolution of quantum systems and entanglement across multiple probes, the precision of estimating a fully connected $k$-body interaction can scale up to $(n^kt)^{-1}$, where $n$ is the number of probes and $t$ is the probing time. However, the optimal scaling may no longer be achievable under quantum noise, and it is important to apply quantum error correction in order to recover this limit. In this work, we study the performance of stabilizer quantum error correcting codes in estimating many-body Hamiltonians under noise. When estimating a fully connected $ZZZ$ interaction under single-qubit noise, we showcase three families of stabilizer codes – thin surface codes, quantum Reed–Muller codes and Shor codes – that achieve the scalings of $(nt)^{-1}$, $(n^2t)^{-1}$ and $(n^3t)^{-1}$, respectively, all of which are optimal with $t$. We further discuss the relation between stabilizer structure and the scaling with $n$, and identify several no-go theorems. For instance, we find codes with constant-weight stabilizer generators can at most achieve the $n^{-1}$ scaling, while the optimal $n^{-3}$ scaling is achievable if and only if the code bears a repetition code substructure, like in Shor code.","PeriodicalId":20807,"journal":{"name":"Quantum","volume":"17 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144218747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"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}
