Many body density of states in the edge of the spectrum: non-interacting limit
Pragya Shukla
In noninteracting limit, the density of states of a many body system can be expressed as the convolution of single body density of states of its subunits. Here we use the formulati…
Boson peak in amorphous systems: role of phonon mediated coupling of nano-clusters
Pragya Shukla
Based on a description of an amorphous solid as a collection of coupled nanosize molecular clusters referred as basic blocks, we analyse the statistical properties of its Hamiltoni…
Low temperature Universalities in amorphous systems: role of microscopic length scales
Pragya Shukla
We find that a competition between dispersion forces among molecules in solids and their phonon mediated coupling leads to a natural length scale based on molecular parameters and…
Low temperature heat capacity of amorphous systems: physics at nano-scales
Pragya Shukla
Contrary to previous studies of boson peak, we analyze the density of states and specific heat contribution of dispersion forces in an amorphous solid of nano-scales ().…
Spectral and Strength Statistics of Chiral Brownian Ensemble
Pragya Shukla
Multi-parametric chiral random matrix ensembles are important tools to analyze the statistical behavior of generic complex systems with chiral symmetry. A recent study \cite{psmult…
Spectral statistics of multi-parametric Gaussian ensembles with chiral symmetry
Triparna Mondal, Pragya Shukla
The statistics of chiral matrix ensembles with uncorrelated but multivariate Gaussian distributed elements is intuitively expected to be driven by many parameters. Contrary to intu…
