Implementation of Clifford gates in the Ising-anyon topological quantum computer
Andre Ahlbrecht, Lachezar S. Georgiev, Reinhard F. Werner
We give a general proof for the existence and realizability of Clifford gates in the Ising topological quantum computer. We show that all quantum gates that can be implemented by b…
Quasar optical variability: searching for interband time delays
Rumen S. Bachev
Aims. The main purpose of this paper is to study time delays between the light variations in different wavebands for a sample of quasars. Measuring a reliable time delay for a larg…
Dual channel self-oscillating optical magnetometer
J. Belfi, G. Bevilacqua, V. Biancalana +4
We report on a two-channel magnetometer based on nonlinear magneto-optical rotation in a Cs glass cell with buffer gas. The Cs atoms are optically pumped and probed by free running…
Diamond chains with multiple-spin exchange interactions
N. B. Ivanov, J. Richter, J. Schulenburg
We study the phase diagram of a symmetric spin-1/2 Heisenberg diamond chain with additional cyclic four-spin exchange interactions. The presented analysis supplemented by numerical…
Polymer desorption under pulling: a novel dichotomic phase transition
S. Bhattacharya, V. G. Rostiashvili, A. Milchev +1
We show that the structural properties and phase behavior of a self-avoiding polymer chain on adhesive substrate, subject to pulling at the chain end, can be obtained by means of a…
Excess Specific Heat of Ptfe and Pctfe at Low Temperatures: Approximation Details
Nina B. Bogdanova, B. M. Terziyska
Approximation of the previously estimated excess specific heat C^{excess}/T^{5} of two fluoropolymers, PTFE and PCTFE, is presented using Orthonormal Polynomial Expansion Method (O…
