Order, Collectivity, Structured Yrast Lines, and Correlated Energies in Random Bosonic Systems

Declan Mulhall

Signatures of order and collectivity appear in a broad range of one and two level boson systems. Toy systems of particles on a single level, and on 2 levels $(…

Are the ground states of randomly interacting bosons random?

Charles White, Alexander Volya, Declan Mulhall +1

Bosonic degrees of freedom and their emergence as a part of complex quantum many-body dynamics, symmetries, collective behavior, clustering and phase transitions play an important…

Open quantum systems and Random Matrix Theory

Declan Mulhall

A simple model for open quantum systems is analyzed with Random Matrix Theory. The system is coupled to the continuum in a minimal way. In this paper we see the effect of opening t…

Calculating and visualizing the density of states for simple quantum mechanical systems

Declan Mulhall, Matthew Moelter

We present a graphical approach to understanding the degeneracy, density of states, and cumulative state number for some simple quantum systems. By taking advantage of basic comput…

A maximum likelihood method to correct for missed levels based on the statistic

Declan Mulhall

The statistic of Random Matrix Theory is defined as the average of a set of random numbers , derived from a spectrum. The distribution of these random number…

Using the statistic to test for missed levels in mixed sequence neutron resonance data

Declan Mulhall

The statistic is studied as a tool to detect missing levels in the neutron resonance data where 2 sequences are present. These systems are problematic because there is no…
