Superconductivity in an uncompensated boron doped diamond, a very recent observation, is strikingly close to an earlier observation of Anderson-Mott insulator to metal transition, prompting us to suggest an electron correlation driven superconductivity in an impurity band. Random coulomb potential remove a three fold orbital degeneracy of boron acceptor states, resulting in an effective single,...

A microscopic configuration-interaction (CI) methodology is introduced to enable bottom-up Schrödinger-equation emulation of unconventional superconductivity in ultracold optical traps. We illustrate the method by exploring the properties of Li atoms in a single square plaquette in the hole-pairing regime, and by analyzing the entanglement (symmetry-preserving) and disentanglement physics (via ...

The INO80 and SWR1 complexes belong to the INO80 subfamily of ATP-dependent chromatin-remodeling complexes. These complexes interact with nucleosomes and remodel chromatin by either sliding nucleosomes along the DNA or exchanging histones within nucleosomes. In doing so, the INO80 and SWR1 complexes promote recruitment of regulatory factors to DNA. Distinct from other subfamilies of chromatin-r...

Within the last four decades, IS and business scholars have shown a growing interest in information technology (IT) investments. As firms continue to make huge investments in IT, it is important to understand how IT provides competitive advantages to the firms. However, the direct effects of IT in creating business advantages are riddled with the productivity paradox. In this research, our goal...

A new method to define a digital signature of a painting is presented. This signature is composed by a set of patches that are automatically selected as the images regions containing the most relevant information. The region selection is applied on a combination of saliency maps related to different features concerning intensity, color and visual saliency. We present the generation of the featu...

The spin-1/2 Heisenberg model on the pyrochlore lattice is an iconic frustrated three-dimensional spin system with a rich phase diagram. Besides hosting several ordered phases, debated to possess spin-liquid ground state when only nearest-neighbor antiferromagnetic interactions are present. Here, we contest this hypothesis extensive numerical investigation using both exact diagonalization and c...

3 To myself 4 I want acknowledge: Sandro Sorella for his patience with me. In these years he taught many things but I spent enough time to understand them (especially his QMC code); Irina Yegorova: My sweet ljubimaja, she corrected my thesis, and promised to listen to my presentation, poor girl; Lorenzo Stella: My personal " contarolo " , since he helped me many many times. It's unbelievable, b...
