Griffiths-McCoy Singularities in the Dilute Transverse-Field Ising Model: A Numerical Linked Cluster Expansion Study
Foster Thompson, Rajiv R. P. Singh
We use Numerical Linked Cluster Expansions (NLCE) to study the site diluted transverse-field Ising model on the square-lattice at . NLCE with a self-consistent mean-field on t…

Contact interactions and Kronig-Penney Models in Hermitian and PT-symmetric Quantum Mechanics
Foster Thompson, Katherine Jones-Smith, Harsh Mathur +1
The delta function potential is a simple model of zero-range contact interaction in one dimension. The Kronig-Penney model is a one-dimensional periodic array of delta functions th…
