The revival of Hebrew is so far the most successful known reclamation of a sleeping tongue and is a language movement that has been in progress for more than 120 years. By comparison, language revival movements in Australia are in their infancy. This paper provides comparative insights and makes information about the Hebrew revival accessible to Australian linguists and Aboriginal revival activ...

The revival structure and evolution of Rydberg wave packets are studied on a time scale much greater than the revival time trev. We find a new level of revival structure and periodic motion different from that of the known fractional revivals. The new sequence of revivals culminates with the formation of a wave packet that more closely resembles the initial packet than does the full revival at ...

Thousands of one of Britain's most spectacular butterflies, which became extinct in the country in 1979, flew again this summer as a result of a careful research, reintroduction and conservation programme that provides a model for other flagship species. The British Large Blue (Maculinea arion) occurs across Europe and northern Asia and is one of six large blue species globally, all of which ar...

In a quantum revival, a localized wavepacket re-forms or ”revives” into a compact reincarnation of itself long after it has spread in an unruly fashion over a region restricted only by the potential energy. This is a purely quantum phenomenon, which has no classical analog. Quantum revival, and Anderson localization, are members of a small class of subtle interference effects resulting in a qua...

We calculate the quantum revival time for a wave-packet initially well localized in a one-dimensional potential in the presence of an external periodic modulating field. The dependence of the revival time on various parameters of the driven system is shown analytically. As an example of application of our approach, we compare the analytically obtained values of the revival time for various modu...

In this paper, we demonstrate that the master slave (MS) interferometry method can significantly simplify the practice of coherence revival swept source optical coherence tomography (OCT) technique. Previous implementations of the coherence revival technique required considerable resources on dispersion compensation and data resampling. The total tolerance of the MS method to nonlinear tuning, ...

We investigate exciton emission of quantum well embedded in a semiconductor microcavity. The analytical expressions of the light intensity for the cases of excitonic number state and coherent state are presented by using secular approximation. Our results show that the effective exciton-exciton interaction leads to the appearance of collapse and revival of the light intensity. The revival time ...

This article explores the Buddhist interactions between Tibet and China in contemporary period. In contrast to recent studies understanding Buddhist revival in Tibet within the framework of ‘ChinaTibet’ divide, this paper reveals that along with Buddhist revival and the creative strategies that Tibetan monks use to accomplish this revival, the interactions and ties between Tibetan and Chinese B...

We study echoes and what we call “revival echoes” for a collection of atoms that are described by a single quantum wave function and are confined in a weakly anharmonic trap. The echoes and revival echoes are induced by applying two successive temporally localized potential perturbations to the confining potential, one at time t = 0, and a smaller one at time t = τ . Pulselike responses in the ...

It is believed so far that the high harmonic generation (HHG) signal of adiabatically aligned molecules does not show any revival structure. This paper demonstrates the existence of revival structure of HHG signals of molecular ensemble aligned by using adiabatic as well as switched-off schema. The results are presented in the externally available control parameters – the delay-time, d t , betw...
