In a broad sense, ultrafast laser pulses (pulsewidth ?t < 1 ps) have three important applications: (i) Inducing a perturbation in a system of study within a time much shorter than the characteristic lifetimes of the system ...

In this thesis, first-principles density functional theory (DFT) calculations are used to study the structural, electronic, elastic, mechanical, and thermal properties in a series of pyrochlore materials. The vibrational ...

In day to day life we encounter many different materials which are intermediate between crystalline solids and simple liquids that include paints , glues , suspensions, polymers, surfactants, food and cosmetic products and ...

Topological insulators (TIs) belong to a new class of materials characterized by linear surface states, which emerge in the bulk band gap due to non-trivial topology of the band structure. These surface states have various ...

The observed fluorescence decay of Mn²? in potassium sulphate–zinc sulphate glass is of single exponential at low (3 mole %) and high concentrations (12 mole %) of manganese. At higher concentrations of manganese, concentration ...

The field of advanced solution processed spin-coated electronics has rapidly expanded over the last few decades towards the development of low-cost, large area and low power consumer electronics for the design of ...

Cosmic rays (CRs) are high-energy particles, predominantly originating from outside the Earth’s atmosphere. These particles, ranging from protons to heavier nuclei, propagate through space at nearly the speed of light, ...

We recount here briefly the main advantages of using the front form for paraxial wave problems. It leads to a clean separation of the space-time variables into the combinations on each of which the amplitude has a ...
