Quantum fluctuations enhanced by frustration and subtle interplay between competing degrees of freedom offer an ideal ground to realize novel states with fractional quantum numbers in materials that defy standard theoretical paradigms. spin liquid (QSL) is a highly entangled state wherein frustration-induced strong preclude symmetry-breaking phase transitions down zero temperature without any order parameter. Experimental realizations QSL dimensionality greater than one very rare. Here, we...
Mono-layer transition metal dichalcogenides (TMDCs) have emerged as an ideal platform for the study of many-body physics. As a result their low dimensionality, these materials show strong Coulomb interaction primarily due to reduced dielectric screening that leads formation stable excitons (bound electron-hole pairs) and higher order excitons, including trions, bi-excitons even at room temperature. van der Waals (vdW) heterostructures (HSs) TMDCs provide additional degree freedom altering...
Temperature-dependent vibrational characteristics of scissors modes α-MoO 3 in terms Fano resonance and anharmonicity.
This work investigates the high-pressure structure of freestanding superconducting ($T_{c}$ = 4.3\,K) boron doped diamond (BDD) and how it affects electronic vibrational properties using Raman spectroscopy x-ray diffraction in 0-30\,GPa range. High-pressure scattering experiments revealed an abrupt change linear pressure coefficients grain boundary components undergo irreversible phase at 14\,GPa. We show that blue shift pressure-dependent modes correlates with negative coefficient $T_{c}$...
We have demonstrated the fabrication of semiconductor microspherical crystals such as ZnO and Si microspheres by a simple laser ablation technique. In addition, doped alloyed achieved this The mechanism spherical is based on instantaneous heating target material, formation shape surface tension liquid-state rapid freezing with keeping shape. study, technique expanded to other various materials, consisting multicomponent Sr3Sn2O7 was successfully fabricated. This candidate for functional crystals.
Outcrossing in rice mainly depends on climatic factors. Favorable environments increase hybrid seed production. Likewise, synchrony flowering of male and female parents also increases set. We therefore conducted two trials to investigate these important aspects. A trial was semiarid humid zones Andhra Pradesh during the 1991-92 wet season (WS) dry (DS), using IR62829A IR62829B a row ratio 4A:2B. Sowings B lines were staggered. Leaf clipping rope pulling adopted. The outcrossing percentage...
