Spectral functions of charmonium from 2 flavour anisotropic lattice data
Aoife Kelly, Jon-Ivar Skullerud, Chris Allton +2
The spectral functions of QCD can give us insight into properties of hadrons, and they are useful in probing the QCD vacuum. I will discuss the correlators and spectral functions o…
Potential Energy Landscapes for the 2D XY Model: Minima, Transition States and Pathways
Dhagash Mehta, Ciaran Hughes, Mario Schröck +1
We describe a numerical study of the potential energy landscape for the two-dimensional XY model (with no disorder), considering up to 100 spins and CPU and GPU implementations of…
Eigenvalue spectrum of lattice super Yang-Mills
David J. Weir, Simon Catterall, Dhagash Mehta
We present preliminary results for the eigenvalue spectrum of four-dimensional super Yang-Mills theory on the lattice. In particular, by studying the the spectral dens…
On exact minimization of Higgs potentials
Markos Maniatis, Dhagash Mehta
Minimizing the Higgs potential is an essential task in any model involving Higgs bosons. Exact minimization methods proposed in the literature are based on the polynomial form of t…
Energy Landscape of the Finite-Size Mean-field 3-Spin Spherical Model
Dhagash Mehta, Daniel A. Stariolo, Michael Kastner
We study the 3-spin spherical model with mean-field interactions and Gaussian random couplings. For moderate system sizes of up to 20 spins, we obtain all stationary points of the…
Tumbling through a landscape: Evidence of instabilities in high-dimensional moduli spaces
Brian Greene, David Kagan, Ali Masoumi +3
We argue that a generic instability afflicts vacua that arise in theories whose moduli space has large dimension. Specifically, by studying theories with multiple scalar fields we…
