Broken ground 9780060915230 1989 John Keeble 336 pages Perennial Library, 1989 Ground-state factorization and correlations with broken symmetry, we show how the phenomenon of factorization in a quantum many-body system is of collective nature. To this aim we study the quantum discord Q in the one-dimensional XY model in a transverse field. We analyze the behavior of Q at both the critical point. Broken parity and a chiral ground state in the frustrated magnet, we present a model describing the lattice distortion and incommensurate magnetic order in the spinel Cd Cr 2 O 4, a good realization of the Heisenberg pyrochlore antiferromagnet. The magnetic frustration is relieved through the spin-Peierls distortion of the lattice involving. Habitat Preferences and Competition of Wintering Juncos and Goldenâ Crowned Sparrows, golden-crowns breed in dense alder, willow, or birch thickets or in heavy brush (Kelly 1968). Winter habitat in California is an interrupted type of brushland, such as consti- tuted by streamside thickets, chaparral where broken up by patches of broken ground, and garden shrub. Do the A4C60 fullerides have a broken-symmetry ground state, band theory predicts both K 3 C 60 and K 4 C 60 to be metals; various experimental probes show that while K 3 C 60 is indeed metallic, K 4 C 60 appears to be insulating. The standard view of this apparent failure of the single-particle picture is that electron correlation. Rigorous results on valence-bond ground states in antiferromagnets, these ground states have a translational symmetry broken from period 1 to period 2, ultrashortrange correlations, and, as we will prove in a companion paper, an energy. S, our models have unique ground states with no broken symmetries. As in the model. Broken-symmetry ground states in bilayer quantum Hall systems, we report on a study of a bilayer two-dimensional electron gas at Landau-level filling factor ν= 2. The system exhibits both magnetic and spontaneous interlayer phase coherence broken symmetries. We propose a three-parameter Slater-determinant variational wave. Earthquakes on dipping faults: the effects of broken symmetry, schematic diagram of the geometry and coordinate system of the fault models, as described (2). For a nonvertical (dipping) fault such as presented here, the symmetry between the two sides of the fault and the free surface is broken. Analyses of ground motion caused by recent. Broken Ground: John F Kennedy and the Politics of Education, throughout United States history, and particularly from the 1930s through the 1960s, education was a sensitive political issue which preoccupied Congresses, Presidents and interest groups. By the time of John F Kennedy s Presidency federal aid to education. Electronic Structure, Metal-Metal Bonding, and Ground-State Exchange Coupling in Face-Shared Mo2X93-(X= Cl, Br, I) Dimers Using the Broken-Symmetry X. alpha, the results of spin-restricted SCF-Xa-SW and spin-unrestricted broken-symmetry SCF-Xa-SW calculations on the face-shared dimer complexes A3Mo2C19 (A= K, Rb, Cs, MedN), A3Mo~ Br9 (A= Cs, Me4N), and Cs3Moz19 are reported and used to discuss the electronic. Quench of a symmetry-broken ground state, we analyze the problem of how different ground states associated with the same set of Hamiltonian parameters evolve after a sudden quench. To realize our analysis we define a quantitative approach to the local distinguishability between different ground states. Parity-broken ground state for the spin-1 pyrochlore antiferromagnet, the ground-state properties of the spin-1 pyrochlore antiferromagnet are studied by applying the VBS-like tetrahedron-unit decomposition to the original spin system. The symmetrization required on every vertex is taken into account by introducing a ferromagnetic. Spontaneously broken ground states of the linear sigma model at large, symmetry breaking patterns of the U (n) L× U (n) R symmetric meson model are investigated in a formulation involving three auxiliary composite fields. The effective potential is constructed at leading order in the 1/n expansion for a condensate belonging to the center. The RED versus NIR plane to retrieve broken-cloud optical depth from ground-based measurements, a new method for retrieving cloud optical depth from groundbased measurements of zenith radiance in the red (RED) and near-infrared (NIR) spectral regions is introduced. Because zenith radiance does not have a one-to-one relationship with optical depth, it is absolutely. Machine invention of first-order predicates by inverting resolution, although conceptual clustering algorithms such as (Michalski & Stepp, 1982; Rendell, 1985) have broken ground within this area, these methods have tended to be limited to the construction of new taxonomic classes within non-relational formalisms. Broken symmetries in a one-dimensional half-filled band with arbitrarily long-range Coulomb interactions, s. Mazumdar and DK Campbell Center for Nonlinear Studies, Los Alamos National Laboratory, Los Alamos, New Mexico 87545 (Received 13 May 198S) The nature of the ground-state broken symmetry in a onedimensional half-filled band with arbi- trarily long-rangeCoulomb. Transport spectroscopy of symmetry-broken insulating states in bilayer graphene, apparently particle-hole asymmetric. These observations provide much insight into the nature of bilayer graphene's symmetry-broken ground state. For instance, observation (i) rules out gapless ordered states 11,12 . For the gapped. Broken-symmetry ground states for the two-dimensional electron gas in a double-quantum-well system, abstract Working in the Hartree-Fock approximation, we calculate the ground-state energy of different states of the two-dimensional electron gas in a double-quantum-well system as a function of the separation of the wells. Our calculation takes tunneling between the wells. Re (-) membering a dismembered body: Memoria passionis as a new horizoning on broken ground, on bodies, body language and embodiment What is a body? In rather neutral terms, the web edition of the Encyclopaedia Britannica 2002 offers, inter alia, the definitions a human being or a sensible object in a physical space. Correct as they may be, I prefer. Double exchange and vibronic coupling in mixed valence systems. Origin of the broken-symmetry ground state of [Fe3S4] 0 cores in proteins and models, the origin of the pair-delocalized ground state of spin S= 2, observed in chemically symmetric mixed-valence [Fe3S4] 0cores present in proteins and synthetic models, is analyzed in the frameworkof an effective-Hamiltonian model, comprising terms for excess. Principle and Practice of Process Control over Soft Broken Roadway with High Ground Stress [J, due to the complexity of occurrence condition and the polytropy of influencing factors, the excavation and supporting in soft failure roadway under high ground stress become very difficult. Based on the analyses of dynamic deformation process of the soft failure roadway.
