Analytical Solution of 2D Dual-Phase-Lagging Heat Conduction Model
The heat transport at microscale is vital important in the field of micro-technology. In this paper heat transport in a two-dimensional thin plate based on dual-phase-lagging (DPL) heat conduction model is investigated. The solution was obtained with the help of superposition techniques and solution structure theorem. . The whole analysis is presented in dimensionless form. A numerical example ...
متن کاملPhase diagram of the bose Hubbard model
The first reliable analytic calculation of the phase diagram of the bose gas on a d-dimensional lattice with on-site repulsion is presented. In one dimension, the analytic calculation is in excellent agreement with the numerical Monte Carlo results. In higher dimensions, the deviations from the Monte Carlo calculations are larger, but the correct shape of the Mott insulator lobes is still obtai...
متن کاملFerromagnetic Phase Transitions in the Hubbard Model
We show that the coupling of charge and spin density fluctuations in the three-dimensional Hubbard model with total charge fixed severely restricts the occurrence of a continuous ferromagnetic transition. This work focuses in one of a series of longstanding problems related to the one-band Hubbard model [I], namely the existence and nature of a finitetemperature ferromagnetic phase transition i...
متن کاملMagnetic phase diagram of the Hubbard model.
The competition between commensurate and incommensurate spin-densitywave phases in the infinite-dimensional single-band Hubbard model is examined with quantum Monte Carlo simulation and strong and weak coupling approximations. Quantum fluctuations modify the weak-coupling phase diagram by factors of order unity and produce remarkable agreement with the quantumMonte Carlo data, but strong-coupli...
متن کاملPhase separation in the Hubbard model.
The Hartree-Fock ground-state phase diagram of the one-dimensional Hubbard model is calculated in the μ−U plane, restricted to phases with no charge density modulation. This allows antiferromagnetism, saturated ferromagnetism, spiral spin density waves and a collinear structure with unit cell ↑↑↓↓. The spiral phase is unstable against phase separation near quarter-, halfand three-quarter-fillin...
