Quantum Momentum Distribution and Quantum Entanglement in the Deep Tunneling Regime
Yantao Wu, Roberto Car
In this paper, we consider the momentum operator of a quantum particle directed along the displacement of two of its neighbors. A modified open-path path integral molecular dynamic…
Dynamical Quantum Phase Transitions of Quantum Spin Chains with the Loschmidt-rate Critical Exponent equal to
Yantao Wu
We describe a new universality class of dynamical quantum phase transitions of the Loschmidt amplitude of quantum spin chains off equilibrium criticality. We demonstrate that in ma…
Dynamical Quantum Phase Transition of the Quantum -state Potts Chain with Quenched Disorder
Yantao Wu
We present an exact renormalization group analysis of the Loschmidt amplitude of the quantum -state Potts chain with random quench-disordered nearest neighbor bonds, under the e…
Non-equilibrium Renormalization Group Fixed-Points of the Quantum Clock Chain and the Quantum Potts chain
Yantao Wu
We derive an exact renormalization group recursion relation for the Loschmidt amplitude of the quantum -state clock model and the quantum -state Potts model in one dimension.…
The Tangent Space to the Manifold of Critical Classical Hamiltonians Representable by Tensor Networks
Yantao Wu
We introduce a scheme to perform Monte Carlo Renormalization Group with the coupling constants of the system Hamiltonian encoded in a tensor network. With this scheme we compute th…
Determination of the Critical Manifold Tangent Space and Curvature with Monte Carlo Renormalization Group
Yantao Wu, Roberto Car
We show that the critical manifold of a statistical mechanical system in the vicinity of a critical point is locally accessible through correlation functions at that point. A pract…
