- Direct Determination of the Base-Pair Force Constant of DNA from the Acoustic Phonon Dispersion of the Double Helix
[作者:van Eijck, L; Merzel, F; Rols, S; Ollivier, J; Forsyth, VT; Johnson, MR,期刊:PHYSICAL REVIEW LETTERS, 页码:88102-88102 , 文章类型: Article,,卷期:2011年107-8]
- Quantifying the molecular elasticity of DNA is fundamental to our understanding of its biological functions. Recently different groups, through experiments on tailored DNA samples and numerical models, have reported a ra...
- Regulating Brownian Fluctuations with Tunable Microscopic Magnetic Traps
[作者:Chen, A; Vieira, G; Henighan, T; Howdyshell, M; North, JA; Hauser, AJ; Yang, FY; Poirier, MG; Jayaprakash, C; Sooryakumar, R,期刊:PHYSICAL REVIEW LETTERS, 页码:87206-87206 , 文章类型: Article,,卷期:2011年107-8]
- A major challenge to achieving positional control of fluid borne submicron sized objects is regulating their Brownian fluctuations. We present a magnetic-field-based trap that regulates the thermal fluctuations of superp...
- Vacancy-Driven Anisotropic Defect Distribution in the Battery-Cathode Material LiFePO(4)
[作者:Lee, JW; Zhou, W; Idrobo, JC; Pennycook, SJ; Pantelides, ST,期刊:PHYSICAL REVIEW LETTERS, 页码:85507-85507 , 文章类型: Article,,卷期:2011年107-8]
- Li-ion mobility in LiFePO(4), a key property for energy applications, is impeded by Fe antisite defects (Fe(Li)) that form in select b-axis channels. Here we combine first-principles calculations, statistical mechanics, ...
- Transport and Accumulation of Spin Anisotropy
[作者:Baumgartel, MME; Hell, M; Das, S; Wegewijs, MR,期刊:PHYSICAL REVIEW LETTERS, 页码:87202-87202 , 文章类型: Article,,卷期:2011年107-8]
- We show that spin anisotropy can be transferred to an isotropic system by transport of a spin-quadrupole moment. We derive the quadrupole moment current and continuity equation and study a spin-valve structure consisting...
- Ultimate Limit of Electron-Spin Precession upon Reflection in Ferromagnetic Films
[作者:Hallal, A; Berdot, T; Dey, P; Bismaths, LT; Joly, L; Bourzami, A; Scheurer, F; Bulou, H; Henk, J; Alouani, M; Weber, W,期刊:PHYSICAL REVIEW LETTERS, 页码:87203-87203 , 文章类型: Article,,卷期:2011年107-8]
- We report the discovery of 180 degrees electron-spin precession in spin-polarized electron-reflection experiments on Fe films on Ag(001), the largest possible precession angle in a single electron reflection. Both experi...
- Criticality of Relaxation in Dislocation Systems
[作者:Ispanovity, PD; Groma, I; Gyorgyi, G; Szabo, P; Hoffelner, W,期刊:PHYSICAL REVIEW LETTERS, 页码:85506-85506 , 文章类型: Article,,卷期:2011年107-8]
- Relaxation processes of dislocation systems are studied by two-dimensional dynamical simulations. In order to capture generic features, three physically different scenarios were studied and power-law decays found for var...
