Title: Quantum ether: Photons and electrons from a rotor model

Abstract

We give an example of a purely bosonic model--a rotor model on the 3D cubic lattice--whose low energy excitations behave like massless U(1) gauge bosons and massless Dirac fermions. This model can be viewed as a ''quantum ether;'' a medium that gives rise to both photons and electrons. It illustrates a general mechanism for the emergence of gauge bosons and fermions known as ''string-net condensation.'' Other, more complex, string-net condensed models can have excitations that behave like gluons, quarks and other particles in the standard model. This suggests that photons, electrons and other elementary particles may have a unified origin: string-net condensation in our vacuum.

  • Results of neutral detector experiments in Compton scattering of quasi-real photons on electrons and positrons are given over the range of total energy of the beams of 2E = 1000 to 1048 MeV. The total cross section of the process and the angular distributions are in full agreement with predictions made on the basis of quantum electrodynamics (QED). The ratio of the observed total cross section of quasi-real photons on electrons to that on positrons is equal to 0.99 +- 0.02. The quantitative limits of the cross section for production of a heavy electron (HE) are established.
  • The problem of interaction of two quasimolecular electrons located at an arbitrary distance from each other and near different atoms (nuclei) is solved. The interaction is considered as a second-order effect of quantum electrodynamics in the coordinate representation. It is shown that consistent account of the natural condition of the interaction symmetry with respect to both electrons leads to the additional contribution to the relativistic interaction of the two quasimolecular electrons compared with both the standard Breit operator and the generalized Breit operator obtained previously [O. N. Gadomskii, Usp. Fiz. Nauk 170, 1145 (2000) [Phys. Usp. 43, 1071 (2000)]]. Themore » generalized Breit-Pauli operator for interaction of two quasimolecular electrons located at an arbitrary distance from each other is obtained.« less
  • We present an approach to the Bose-Hubbard model using the U(1) quantum rotor description. The effective action formalism allows us to formulate a problem in the phase only action and obtain analytical formulas for the critical lines. We show that the nontrivial U(1) phase field configurations have an impact on the phase diagrams. The topological character of the quantum field is governed by terms of the integer charges--winding numbers. The comparison of presented results to recently obtained quantum Monte Carlo numerical calculations suggests that the competition between quantum effects in strongly interacting boson systems is correctly captured by our model.
  • Using a simple method analogous to a quantum rephasing technique, a simple modification to a paradigm of classical and quantum chaos is proposed. The interesting quantum maps thus obtained display remarkably rich quantum dynamics. Emphasis is placed on the destruction of dynamical localization without breaking periodicity, unbounded quantum anomalous diffusion in integrable systems, and transient dynamical localization. Experimental realizations of this work are also discussed.
  • Full dimensional wavepacket calculations were carried out on ArI{sub 2} vibrational predissociation with total angular momentum J = 10. For five different values of initial I{sub 2} excitation, we consider the 21 lowest energy levels, corresponding roughly to the 2J + 1 asymmetric rotor levels superimposed on the zero-point motion of the Van der Waals degrees of freedom. In spite of the increased number of available states as J increases, fragmentation occurs via a sparse limit intramolecular vibrational energy redistribution mechanism involving passage through a few intermediate dark states. In addition, averaging over the rotor states does not negate ormore » even decrease vibrational specificity.« less
