Qubit discretizations of d=3 conformal field theories
Hansen S. Wu, Ribhu K. Kaul
We propose that scaling dimensions of d=3 conformal field theories can be studied on a system of qubits with near term quantum simulation platforms. Our proposal chooses couplings…
Projected Density Matrix Sampling for Lattice Hamiltonians
Abhishek Karna, Hansen S. Wu, Shailesh Chandrasekharan +1
Quantum Monte Carlo methods are powerful tools for studying quantum many-body systems but face difficulties in accessing excited states and in treating sign problems. We present a…
Phase diagrams of S=1/2 bilayer Models of SU(2) symmetric antiferromagnets
Fan Zhang, Nisheeta Desai, Wenan Guo +1
We study the phase diagrams of models of bilayers of square lattices antiferromagnets with SU(2) Heisenberg symmetry that have 2, 4, and 6 spin exchanges. We study tw…
First-order Néel-VBS transition in antiferromagnets
Fan Zhang, Wenan Guo, Ribhu K. Kaul
We study the transition between Néel and columnar valence-bond solid ordering in two-dimensional square lattice quantum antiferromagnets with SO(3) symmetry. According to t…
Transverse Field -Matrix Spin Chains
Rui Xian Siew, Shailesh Chandrasekharan, Ribhu K. Kaul
We introduce a simple lattice spin model that is written in terms of the well-known four-dimensional -matrix representation of the Clifford algebra. The local spins with a four-…
Phase diagram of a square lattice model of XY Spins with direction-dependent interactions
Fan Zhang, Wenan Guo, Ribhu K. Kaul
We study a generalization of the well-known classical two-dimensional square lattice compass model of XY spins (sometimes referred to as the 90 compass model), which interp…
