Short title: Embryo responses to diet lead to adult disease Summary sentence: Maternal low protein diet induces compensatory responses within mouse early embryos to enhance growth and nutrient...
Energy functional for the three-level Lipkin model (2008)
Bertolli, Michael G., Papenbrock, Thomas
We compute the energy functional of a three-level Lipkin model via a Legrendre transform and compare exact numerical results with analytical solutions obtained from the random phase approximation...
Watkins, Adam J., Ursell, Elizabeth, Panton, Rose, Papenbrock, Thomas, Hollis, Lisa, Cunningham, Colm, ...
Poor maternal nutrition during pregnancy can alter postnatal phenotype and increase susceptibility to adult cardiovascular and metabolic diseases. However, underlying mechanisms are largely unknown....
Odd-even binding effect from random two-body interactions (2002)
Papenbrock, Thomas, Kaplan, Lev, Bertsch, George F.
Systematic odd-even binding energy differences in finite metallic particles are usually attributed to mean-field orbital energy effects or to a coherent pairing interaction. We show analytically and...
Universal solutions for interacting bosons in one-dimensional harmonic traps (2001)
We consider systems of interacting bosons confined to one-dimensional harmonic traps. In the limit of perturbatively weak two-body interactions the system exhibits several universal states that are...
Exact solutions for interacting boson systems under rotation (2000)
Papenbrock, Thomas, Bertsch, George F.
We study a class of interacting, harmonically trapped boson systems at angular momentum L. The Hamiltonian leaves a L-dimensional subspace invariant, and this permits an explicit solution of several...
Spin Structure of Many-Body Systems with Two-Body Random Interactions (2000)
Kaplan, Lev, Papenbrock, Thomas, Johnson, Calvin W.
We investigate the spin structure of many-fermion systems with a spin-conserving two-body random interaction. We find a strong dominance of spin-0 ground states and considerable correlations between...
Rotational spectra of weakly interacting Bose-Einstein condensates (2000)
Papenbrock, Thomas, Bertsch, George F.
We study the spectrum of rotating Bose-Einstein Condensates in the limit of weak repulsive interactions and present analytical and numerical results for energies and wave functions. While the...
Genomic instability-based transgenic models of prostate cancer (2000)
Voelkel-Johnson, Christina, Voeks, Dale J., Greenberg, Norman M., Barrios, Roberto, Maggouta, Frideriki, Kurtz, David T., ...
To develop animal models that represent the broad spectrum of human prostate cancer, we created transgenic mice with targeted prostate-specific expression of two genes (EcoRI and c-fos) implicated in...
Wave Function Structure in Two-Body Random Matrix Ensembles (1999)
Kaplan, Lev, Papenbrock, Thomas
We study the structure of eigenstates in two-body interaction random matrix ensembles and find significant deviations from random matrix theory expectations. The deviations are most prominent in the...
Numerical study of a three-dimensional generalized stadium billiard (1999)
We study a generalized three-dimensional stadium billiard and present strong numerical evidence that this system is completely chaotic. In this convex billiard chaos is generated by the defocusing...
Lyapunov exponents and Kolmogorov-Sinai entropy for a high-dimensional convex billiard (1999)
We compute the Lyapunov exponents and the Kolmogorov-Sinai (KS) entropy for a self-bound N-body system that is realized as a convex billiard. This system exhibits truly high-dimensional chaos, and...
Yrast line for weakly interacting trapped bosons (1999)
Bertsch, George F., Papenbrock, Thomas
We compute numerically the yrast line for harmonically trapped boson systems with a weak repulsive contact interaction, studying the transition to a vortex state as the angular momentum L increases...
A classical two-body Hamiltonian model and its mean field approximation (1999)
Bertsch, George F., Papenbrock, Thomas, Reddy, Sanjay
We extend a recent billiard model of the nuclear N-body Hamiltonian to consider a finite two-body interaction. This permits a treatment of the Hamiltonian by a mean field theory, and also allows the...
Collective and chaotic motion in self-bound many-body systems (1999)
We investigate the interplay of collective and chaotic motion in a classical self-bound N-body system with two-body interactions. This system displays a hierarchy of three well separated time scales...
Quantization of a billiard model for interacting particles (1999)
Papenbrock, Thomas, Prosen, Tomaz
We consider a billiard model of a self-bound, interacting three-body system in two spatial dimensions. Numerical studies show that the classical dynamics is chaotic. The corresponding quantum system...
Pairing in low-density Fermi gases (1998)
Papenbrock, Thomas, Bertsch, George F.
We consider pairing in a dilute system of Fermions with a short-range interaction. While the theory is ill-defined for a contact interaction, the BCS equations can be solved in the leading order of...
Nonergodic Behavior of Interacting Bosons in Harmonic Traps (1998)
Papenbrock, Thomas, Bertsch, George F.
We study the time evolution of a system of interacting bosons in a harmonic trap. In the low-energy regime, the quantum system is not ergodic and displays rather large fluctuations of the ground...
Guhr, Thomas, Papenbrock, Thomas
We compute the spectral correlation functions for the transition from a harmonic oscillator towards the Gaussian Unitary Ensemble (GUE). We use a variant of the supersymmetry method to obtain...
Bremsstrahlung in Alpha-Decay (1998)
Papenbrock, Thomas, Bertsch, George F.
We present the first fully quantum mechanical calculation of photon radiation accompanying charged particle decay from a barrier resonance. The soft-photon limit agrees with the classical results,...
