These results and high-resolution ki... Transient Solar Oscillations Driven by Primordial Black Holes [作者：Kesden, M; Hanasoge, S,期刊：PHYSICAL REVIEW LETTERS, 页码：111101-111101 , 文章类型： Article，,卷期：2011年107-11] Stars are transparent to the passage of primordial black holes (PBHs) and serve as seismic detectors for such objects. The gravitational field of a PBH squeezes a star and causes it to ring acoustically. We calculate the... Direct Sampling of Negative Quasiprobabilities of a Squeezed State [作者：Kiesel, T; Vogel, W; Hage, B; Schnabel, R,期刊：PHYSICAL REVIEW LETTERS, 页码：113604-113604 , 文章类型： Article，,卷期：2011年107-11] Although squeezed states are nonclassical states, so far, their nonclassicality could not be demonstrated by negative quasiprobabilities. In this work we derive pattern functions for the direct experimental determination... Predicted Formation of Superconducting Platinum-Hydride Crystals under Pressure in the Presence of Molecular Hydrogen [作者：Kim, DY; Scheicher, RH; Pickard, CJ; Needs, RJ; Ahuja, R,期刊：PHYSICAL REVIEW LETTERS, 页码：117002-117002 , 文章类型： Article，,卷期：2011年107-11] Noble metals adopt close-packed structures at ambient pressure and rarely undergo structural transformation at high pressures. Platinum (Pt) is normally considered to be unreactive and is therefore not expected to form h... Volume Dependence of Bound States with Angular Momentum [作者：Konig, S; Lee, D; Hammer, HW,期刊：PHYSICAL REVIEW LETTERS, 页码：112001-112001 , 文章类型： Article，,卷期：2011年107-11] We derive general results for the mass shift of bound states with angular momentum l >= 1 in a finite periodic volume. Our results have direct applications to lattice simulations of hadronic molecules as well as atomic n... Large-Deviation Approach to Space-Time Chaos [作者：Kuptsov, PV; Politi, A,期刊：PHYSICAL REVIEW LETTERS, 页码：114101-114101 , 文章类型： Article，,卷期：2011年107-11] In this Letter, we show that the analysis of Lyapunov-exponent fluctuations contributes to deepen our understanding of high-dimensional chaos. This is achieved by introducing a Gaussian approximation for the large-deviat... Effects of Demographic Noise on the Synchronization of a Metapopulation in a Fluctuating Environment [作者：Lai, YM; Newby, J; Bressloff, PC,期刊：PHYSICAL REVIEW LETTERS, 页码：118102-118102 , 文章类型： Article，,卷期：2011年107-11] We use the theory of noise-induced phase synchronization to analyze the effects of demographic noise on the synchronization of a metapopulation of predator-prey systems within a fluctuating environment (Moran effect). Tr... Molecular Prototypes for Spin-Based CNOT and SWAP Quantum Gates [作者：Luis, F; Repolles, A; Martinez-Perez, MJ; Aguila, D; Roubeau, O; Zueco, D; Alonso, PJ; Evangelisti, M; Camon, A; Sese, J; Barrios, LA; Aromi, G,期刊：PHYSICAL REVIEW LETTERS, 页码：117203-117203 , 文章类型： Article，,卷期：2011年107-11] We show that a chemically engineered structural asymmetry in [Tb(2)] molecular clusters renders the two weakly coupled Tb(3+) spin qubits magnetically inequivalent. The magnetic energy level spectrum of these molecules m...
