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 کاملapplying transitivity theory to gender analysis of efl textbook: : a comparative study.
efl/esl textbooks have been regarded as essential language teaching materials with which the learners spend about 70 up to 90 percent of their class time. the important role they play and their vast use make them not only influential in learning the language but also in shaping values and attitudes. put it another way, textbooks socialize learners using their contents (i.e. texts, illustrations...
15 صفحه اولTowards a Coherent Theory of Animal Equality
In this article I want to construct in a simple and systematic way an ethical theory of animal equality. The goal is a consistent theory containing a set of clear and coherent universalized ethical principles that best fits our strongest moral intuitions in all possible morally relevant situations that we can think of, without too many arbitrary elements. I demonstrate that impartiality with a ...
متن کاملA Simple Theory of Optimal Coherent Control
By combining the theories of optimal control and coherent control, we derive an analytical formulation to evaluate the optimal 1-photon and n-photon fields together with their relative phase and intensity in the optimal “1 + n”-coherent control scheme. The optimal coherent control exploits tailored light pulses to produce the best overlap with a predefined nuclear target in an electronically de...
متن کاملToward a Theory of Learning Coherent Concepts
We develop a theory for learning scenarios where multiple learners co-exist but there are mutual compatibility constraints on their outcomes. This is natural in cognitive learning situations, where “natural” compatibility constraints are imposed on the outcomes of classifiers so that a valid sentence, image or any other domain representation is produced. We suggest that work in this direction m...
