Admissibility of Kneading Sequences and Structure of Hubbard Trees for Quadratic Polynomials
Hubbard trees are invariant trees connecting the points of the critical orbits of postcritically finite polynomials. Douady and Hubbard [DH1] introduced these trees and showed that they encode the essential information of Julia sets in a combinatorial way. The itinerary of the critical orbit within the Hubbard tree is encoded by a (pre)periodic sequence on {0, 1} called kneading sequence. We pr...
متن کاملPopulation and biomass dynamics of trees in a northern hardwood forest at Hubbard Brook
We quantified the dynamics of the tree stratum at Hubbard Brook Experimental Forest (HBEF), New Hampshire, to examine why live biomass reached a plateau in about 1980. Total aboveground biomass increased from 209 Mg ha–1 in 1981 to 216 Mg ha–1 in 2001. From 1991 to 2001, in-growth of ‡10 cm diameter at breast height (DBH) trees averaged 4.7 trees ha–1 year –1 with a corresponding in-growth biom...
متن کاملHole doped Hubbard ladders
The formation of stripes in six-leg Hubbard ladders with cylindrical boundary conditions is investigated for two different hole dopings, where the amplitude of the hole density modulation is determined in the limits of vanishing DMRG truncation errors and infinitely long ladders. The results give strong evidence that stripes exist in the ground state of these systems for strong but not for weak...
متن کاملThe Hubbard Quantum Wire
By introducing a boundary condition for the quantum wire, the Hubbard model is solved exactly by means of the Bethe ansatz. The wave function for the bounded state is clearly defined, and the secular equation for the spectrum is exactly obtained. The ground state and low-lying excited states are studied in the thermodynamic limit. The ground-state energy in the strong coupling limit is obtained...
متن کاملThe Bose-Hubbard Hamiltonian
One of the exciting prospects of the physics of dilute bose gasses is the realization of optical lattices. The combination of many body physics together with a high degree of tunability makes these systems promising test beds for theoretical techniques and novel devices. In particular given their high degree of quantum coherence they represent the (long term) possibility of a universal quantum ...
