متن کاملeffect of oral presentation on development of l2 learners grammar
this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولEffect of thermal phase fluctuations on the inductances of Josephson junctions, arrays of junctions, and superconducting films
We calculate the factor by which thermal phase fluctuations, as distinct from phase-slip fluctuations, increase the inductance LJ of a resistively shunted Josephson junction ~JJ! above its mean-field value L0 . We find that quantum mechanics suppresses fluctuations when T drops below a temperature, TQ5\/kBGL0 , where G is the shunt conductance. Examination of the calculated sheet inductance LA(...
متن کاملJosephson Tunneling at the Atomic Scale: The Josephson Effect as a Local Probe
The aim of this thesis is to characterize the properties of a Josephson junction in a Scanning Tunneling Microscope (STM) at millikelvin temperatures and to implement Josephson STM (JSTM) as a versatile probe at the atomic scale. To this end we investigate the I (VJ) tunneling characteristics of the Josephson junction in our STM at a base temperature of 15 mK by means of current-biased and volt...
متن کاملKaon Zero-Point Fluctuations in Neutron Star Matter
We investigate the contribution of zero-point motion, arising from uctuations in kaon modes, to the ground state properties of neutron star matter containing a Bose condensate of kaons. The zero-point energy is derived via the thermodynamic partition function, by integrating out uctuations for an arbitrary value of the condensate eld. It is shown that the vacuum counterterms of the chiral Lagra...
