Editorial: Whither Letters? - Physical Review Journals Editorial: Whither Letters? When Sam Goudsmit launched Physical Review Letters in 1958, he described PRL as “an experiment [1] Today, we announce a new element of this long-running experiment: End ” Matter Short communications had been a part of our journals since 1929, when the Letters to the Editor section debuted in Physical Review
Multi-GeV Electron Acceleration in Wakefields Strongly Driven by . . . The LWFA is a relativistic accelerating structure result-ing from the space charge separation created by an intense laser pulse passing through an underdense plasma [16] To attain the highest energies, the laser pulse must be guided over many Rayleigh lengths, which can be achieved by using plasma waveguides [10,12] It is also common to use self-guiding [17 –19], where diffraction of the
Preparation of Matrix Product States with Log-Depth Quantum Circuits One of the most important tasks in many-body physics and quantum information science is the preparation of useful or relevant states This has spurred a large effort to find ways to prepare states, for example, adiabatically [1], dissipatively [2,3], or using quantum circuits A natural class of states to consider are matrix product states (MPS), because they efficiently approximate ground
Ubiquitous Superconducting Diode Effect in Superconductor Thin Films Introduction —Similar to a conventional semiconductor diode, a superconductor with nonreciprocal current flow, a superconducting (SC) diode, may form building blocks for, e g , dissipationless SC digital logic The recent observation of such a SC diode effect in a complex thin film super-conductor heterostructure subjected to an external magnetic field has stimulated vigorous activity
Long-Lived Coherence on a Scale Optical Magnetic Quadrupole Transition Recently, clock transitions have found promising appli-cations in quantum computing with atom arrays, where metastable clock states can serve as excellent qubits and present a gateway for high-fidelity two-qubit gates [2,3,15] Single-qubit gates have been demonstrated on the 1S 0–3P 0 transition in two-electron atoms and second-scale atomic coherence times have been observed [2,16
Giant Magnetoresistance of (001)Fe (001)Cr Magnetic Superlattices molecular-beam epitaxy A huge magnetoresistance is found in superlattices with thin Cr layers: For example, with rc, =9 A, at T =4 2 K, the resistivity is lowered by almost a factor of 2 in a magnetic field of 2 T We ascribe this giant magnetoresistance to spin-dependent transmission of the conduction electrons be-tween
Exploiting Ne20 Isotopes for Precision Characterizations of . . . 1 139ð6Þstatð39Þsyst þ 16O collisions for the 1% most central events At the same time, theoretical uncertainties largely cancel when studying relative variations of observables between two systems This demonstrates a method based on experiments with two light-ion species for precision characterizations of the collective dynamics and its emergence in a small system
Observation of Exceptional Points in Thermal Atomic Ensembles Here we propose a new paradigm for studying the non-Hermitian physics by taking advantage of the rich energy level structure and couplings in thermal atomic ensembles We experimentally observe EPs in thermal atomic ensem-bles and realize enhanced sensing of the magnetic field, for the first time as far as we know Moreover, instead of measuring the transmission spectrum in conventional
Observation of + + and First Experimental Study BESIII detector, we report the first observation of the semileptonic decay of including systematic uncertainties, and an improved measurement of
Matching Matched Filtering with Deep Networks for Gravitational-Wave . . . We report on the construction of a deep convolutional neural network that can reproduce the sensitivity of a matched-filtering search for binary black hole gravitational-wave signals The standard method for the detection of well-modeled transient gravitational-wave signals is matched filtering We use only whitened time series of measured gravitational-wave strain as an input, and we train
