Qubit regularization of asymptotic freedom
Tanmoy Bhattacharya, Alexander J. Buser, Shailesh Chandrasekharan +2
We provide strong evidence that the asymptotically free (1+1)-dimensional non-linear O(3) sigma model can be regularized using a quantum lattice Hamiltonian, referred to as the "He…
A qubit regularization of the sigma model
Hersh Singh, Shailesh Chandrasekharan
We construct a qubit regularization of the non-linear sigma model in two and three spatial dimensions using a quantum Hamiltonian with two qubits per lattice site. Using a w…
Few-body physics on a space-time lattice in the worldline approach
Hersh Singh, Shailesh Chandrasekharan
We formulate the physics of two species of non-relativistic hard-core bosons with attractive or repulsive delta function interactions on a space-time lattice in the worldline appro…
