Coherent delocalization of atomic wave packets in driven lattice potentials.
Atomic wave packets loaded into a phase-modulated vertical optical-lattice potential exhibit a coherent delocalization dynamics arising from intraband transitions among Wannier-Stark levels. Wannier-Stark intraband transitions are here observed by monitoring the in situ wave-packet extent. By varying the modulation frequency, we find resonances at integer multiples of the Bloch frequency. The r...
متن کاملTetramers with vacancies on the square lattice
Two-dimensional dimer models were introduced in statistical mechanics in the 1930s to study the adsorption of diatomic molecules on a surface [1]. In its basic formulation, a dimer on a two-dimensional lattice is an object that lives on a bond b between two nearest-neighbour sites with some associated activity zb = exp−εb/kT where εb may be thought of as the adsorption energy of the dimer. The ...
متن کاملThreshold energy for atomic displacement in electron irradiated germanium
2014 n-type germanium has been irradiated with electrons of various energies in the range 0.5 to 3 MeV. Using transient capacitance measurements we observed four majority carrier traps associated with levels at 0.27 eV (E1), 0.39 eV (E2), 0.35 eV (E4), 0.32 eV (E5) below the conduction band. We have studied the variations of the introduction rates of these traps with the energy of irradiation. ...

توابع درهم نقش بسیار مهم در سیستم های رمزنگاری و پروتکل های امنیتی دارند. در سیستم های رمزنگاری برای دستیابی به احراز درستی و اصالت داده دو روش مورد استفاده قرار می گیرند که عبارتند از توابع رمزنگاری کلیددار و توابع درهم ساز. توابع درهم ساز، توابعی هستند که هر متن با طول دلخواه را به دنباله ای با طول ثابت تبدیل می کنند. از جمله پرکاربردترین و معروف ترین توابع درهم می توان توابع درهم ساز md4, md...
Atomic structure of titania nanosheet with vacancies
Titania nanosheets are two-dimensional single crystallites of titanium oxide with a thickness of one titanium or two oxygen atoms, and they show attractive material properties, such as photocatalytic reactions. Since a titania (Ti₀.₈₇O₂) nanosheet is synthesized by the delamination of a parent layered K₀.₈Ti₁.₇₃Li₀.₂₇O₄ crystal using a soft chemical procedure, substantial Ti vacancies are expec...
