The Partition Function Zeroes of Quantum Critical Points
P. R. Crompton
The Lee-Yang theorem for the zeroes of the partition function is not strictly applicable to quantum systems because the zeroes are defined in units of the fugacity , and t…

Lorentz Covariance and the Dimensional Crossover of 2d-Antiferromagnets
P. R. Crompton
We derive a lattice -function for the 2d-Antiferromagnetic Heisenberg model, which allows the lattice interaction couplings of the nonperturbative Quantum Monte Carlo vacuum to…

Nonperturbative Renormalization of the Heisenberg Spin-1/2 Antiferromagnet on the Square Lattice
P. R. Crompton
We investigate the critical scaling of the spin-1/2 antiferromagnet on the square lattice in the easy-plane (XXZ) regime, via numerical measurements of the entanglement entropy con…
