Average Spectral Density of Multiparametric Gaussian Ensembles of Complex Matrices
Mohd. Gayas Ansari, Pragya Shukla
A statistical description of part of a many body system often requires a non-Hermitian random matrix ensemble with nature and strength of randomness sensitive to underlying system…
Entanglement dynamics of multi-parametric random states: a single parametric formulation
Devanshu Shekhar, Pragya Shukla
A non-ergodic quantum state of a many body system is in general random as well as multi-parametric, former due to a lack of exact information due to complexity and latter reflectin…
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…
Universality of Ultrasonic attenuation in amorphous systems at low temperatures
Pragya Shukla
The competition between unretarded dispersion interactions between molecules prevailing at medium range order length scales and their phonon induced coupling at larger scales leads…
