Ab initio approaches to nuclear structure and scattering
… λϕ^4 interaction. We find surprisingly complex structures with regards to critical coupling phenomena and conduct extensive error analysis. The results help us to better understand phase transitions for not only the ϕ^4 problem, but also to other more realistic problems involving quarks and …

Inelastic electron scattering and nuclear structure in 140Ce
High-resolution inelastic electron scattering has been performed on 14°Ce. A search for high-spin, stretched-configuration transitions lead to the identification of a J1r = 12- state at 6.31 MeV. This transition has only 8% of the calculated single-particle strength. The absence of strong high-spin …

Advances in ab initio approaches to nuclear structure, reaction and nucleonic dynamics
… basis function method to solve the nuclear structure and scattering problems in a unified manner. We apply this method to a test problem: the Coulomb excitation of a trapped deuteron by an impinging heavy ion. The states of the deuteron system are obtained by the {\it ab initio} …

Nuclear structure in 16O measured with (e,e´γ) coincident electron scattering
Some long-standing problems in nuclear structure were studied in 160 using the ( e,e'1) coincident electron scattering probe. Data at two momentum transfers ( q = 0.35 and 0.51 fm-1) were obtained using the MUSL-2A accelerator at the University of Illinois. The photons were detected using a new BaF …

Novel Single Cell Methods to Identify the Genetic Composition at a Single Nuclear Structure
… or the ligation of oligo probes to subnuclear sites of double stranded breaks induced by 2-photon irradiation. It is demonstrated that these techniques afford the ability to identify loci occupying a shared site at a single nuclear substructure, and are thus uniquely suited for …

NUCLEAR COLLECTIVE MODES AT FINITE TEMPERATURE AS A PROBE OF NUCLEAR STRUCTURE AND DYNAMICS
The framework of this Thesis is the study of nuclear structure and reaction dynamics through gamma-spectroscopy measurements in fusion-evaporation reactions. The gamma emission associated with the Dynamical Dipole (DD) mode and the Giant Dipole Resonance (GDR) is a very good tool to study the role …

From Hypernuclei to Hypermatter: a Quantum Monte Carlo Study of Strangeness in Nuclear Structure and Nuclear Astrophysics
… in Quantum Monte Carlo calculations for nuclear systems including strange degrees of freedom. The Auxiliary Field Diffusion Monte Carlo algorithm has been extended to the strange sector by the inclusion of the lightest among the hyperons, the Λ particle. This allows to perform detailed …

BETA DECAY STUDIES AS A TOOL TO INVESTIGATE NUCLEAR STRUCTURE IN THE N-RICH PO-FR REGION AND IN P-RICH CD ISOTOPES
… in isotopes of all known elements along the nuclear chart. This makes it a formidable tool to probe the internal structure of nuclei both on the proton- and neutron-rich exotic nuclei, at the limit of the existence of the nucleus. The work presented in this thesis is focused on experimental …

Improving the Dispersive Optical Model toward a Dispersive Self-energy Method
… is improved, providing a tighter link between nuclear reactions and nuclear structure. In particular, since the self-energy is inherently nonlocal, an explicitly nonlocal term is incorporated in the real part of the dispersive optical potential, which has been assumed to be local in previous …

Biomechanical regulation of epigenetics and chromatin organization in single living cells
… forces play critical roles in regulating nuclear structure and function. Biomechanical cues can propagate deep inside the nucleus and regulate epigenetics, chromatin organization, and gene expression.
