Crystalline character of high-magnetic-field cusp states in quantum dots

Conditional probability distributions from exact diagonalization are used to investigate the crystalline or liquid character of the downward cusp states in parabolic quantum dots (QD’s) at high magnetic fields. These states are crystalline in character for fractional fillings covering both low and high values, unlike the liquid Jastrow-Laughlin wave functions, but in remarkable agreement with t...

Behavioral Factors and Information Technology Infrastructure Considerations in Strategic Alliance Development

Since behavioral and cultural factors play a major role in strategic alliances between partners, IT managers must understand the intricacies involved in the development of resultant IT infrastructure in satisfying both business requirements and cultural fit of the aligned partnering units. This paper first highlights the IT-related issues and cultural issues which are important in the process o...

A simple coding procedure enhances a neuron's information capacity.

The contrast-response function of a class of first order interneurons in the fly's compound eye approximates to the cumulative probability distribution of contrast levels in natural scenes. Elementary information theory shows that this matching enables the neurons to encode contrast fluctuations most efficiently.

Structural properties of electrons in quantum dots in high magnetic fields: Crystalline character of cusp states and excitation spectra

The crystalline or liquid character of the downward cusp states in N-electron parabolic quantum dots at high magnetic fields is investigated using conditional probability distributions obtained from exact diagonalization. These states are of crystalline character for fractional fillings covering both low and high values, unlike the liquid Jastrow-Laughlin wave functions, but in remarkable agree...
