Detection of Nuclear Sources in Search Applications using Dynamic Quantum Clustering of Spectral Data
Marvin Weinstein, Alexander Heifetz, Raymond Klann
In a search scenario, nuclear background spectra are continuously measured in short acquisition intervals with a mobile detector-spectrometer. Detecting sources from measured data…
Analyzing Big Data with Dynamic Quantum Clustering
M. Weinstein, F. Meirer, A. Hume +6
How does one search for a needle in a multi-dimensional haystack without knowing what a needle is and without knowing if there is one in the haystack? This kind of problem requires…
p6 - Chiral Resonating Valence Bonds in the Kagome Antiferromagnet
Sylvain Capponi, V. Ravi Chandra, Assa Auerbach +1
The Kagome Heisenberg antiferromagnet is mapped onto an effective Hamiltonian on the star superlattice by Contractor Renormalization. Comparison of ground state energies on large l…
Reducing Memory Cost of Exact Diagonalization using Singular Value Decomposition
Marvin Weinstein, Assa Auerbach, V. Ravi Chandra
We present a modified Lanczos algorithm to diagonalize lattice Hamiltonians with dramatically reduced memory requirements, {\em without restricting to variational ansatzes}. The la…
A Different Look at Dark Energy and the Time Variation of Fundamental Constants
Marvin Weinstein
This paper makes the simple observation that a fundamental length, or cutoff, in the context of Friedmann-Lemaître-Robertson-Walker (FRW) cosmology implies very different things th…
Massive Degeneracy and Goldstone Bosons: A Challenge for the Light Cone
Marvin Weinstein
Wherein it is argued that the light front formalism has problems dealing with Goldstone symmetries. It is further argued that the notion that in hadron condensates can explain Gold…
