Simultaneous diagonal and off-diagonal order in the Bose-Hubbard Hamiltonian.
The Bose-Hubbard model exhibits a rich phase diagram consisting both of insulating regimes where diagonal long range (solid) order dominates as well as conducting regimes where off diagonal long range order (superfluidity) is present. In this paper we describe the results of Quantum Monte Carlo calculations of the phase diagram, both for the hard and soft core cases, with a particular focus on ...
متن کاملDiagonal Dominance and Harmless Off-diagonal Delays
Systems of linear differential equations with constant coefficients, as well as Lotka–Volterra equations, with delays in the off–diagonal terms are considered. Such systems are shown to be asymptotically stable for any choice of delays if and only if the matrix has a negative weakly dominant diagonal.
متن کاملOff - Diagonal
Experience shows that there is a strong parallel between metrization theory for compact spaces and for linearly ordered spaces in terms of diagonal conditions. Recent theorems of Gruenhage, Pelant, Kombarov, and Stepanova have described metrizability of compact (and related) spaces in terms of the offdiagonal behavior of those spaces, i.e., in terms of properties of X −∆. In this paper, we show...
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 ...
متن کاملCoexistence of diagonal and off-diagonal long-range order: A Monte Carlo study.
The zero temperature properties of interacting 2 dimensional lattice bosons are investigated. We present Monte Carlo data for soft-core bosons that demonstrate the existence of a phase in which crystalline long-range order and off-diagonal long-range order (superfluidity) coexist. We comment on the difference between hard and soft-core bosons and compare our data to mean-field results that pred...
