Zigzag phase transition in quantum wires.
We study the quantum phase transition of interacting electrons in quantum wires from a one-dimensional (1D) linear configuration to a quasi-1D zigzag arrangement using quantum Monte Carlo methods. As the density increases from its lowest values, first, the electrons form a linear Wigner crystal, then, the symmetry about the axis of the wire is broken as the electrons order in a quasi-1D zigzag ...

متن کاملConductance oscillations in zigzag platinum chains.
Using first principles simulations we perform a detailed study of the structural, electronic, and transport properties of monatomic platinum chains, sandwiched between platinum electrodes. First, we demonstrate that the most stable atomic configuration corresponds to a zigzag arrangement that gradually straightens as the chains are stretched. Second, we find that the averaged conductance shows ...
متن کاملTransition Effect Matrices and Quantum Markov Chains
A transition effect matrix (TEM) is a quantum generalization of a classical stochastic matrix. By employing a TEM we obtain a quantum generalization of a classical Markov chain. We first discuss state and operator dynamics for a quantum Markov chain. We then consider various types of TEMs and vector states. In particular, we study invariant, equilibrium and singular vector states and investigat...
متن کاملQuantum Phase Transition in an Ion Trap
English This thesis considers the interaction between N ions confined in an ion trap and a set of laser fields, described by the Dicke model. The Dicke Hamiltonian for the two different models, used by the research group at the University of Innsbruck (the Quantum Optics and Spectroscopy group) and the Quantum Optics group at the National Institute of Science and Technology in Boulder, Colorado...
