Título: | Continuous-matrix-product-state solution for the mixing-demixing transition in one-dimensional quantum fields |
Autor: | Quijandría, Fernando CSIC; Zueco, David CSIC ORCID | Fecha de publicación: | 2015 | Editor: | American Physical Society | Citación: | Physical Review A 92(4): 043629 (2015) | Resumen: | We solve the mixing-demixing transition in repulsive one-dimensional Bose-Bose mixtures. This is done numerically by means of the continuous matrix product states variational ansatz. We show that the effective low-energy bosonization theory is able to detect the transition whenever the Luttinger parameters are exactly computed. We further characterize the transition by calculating the ground-state energy density, the field-field fluctuations, and the density correlations. | Versión del editor: | http://dx.doi.org/10.1103/PhysRevA.92.043629 | URI: | http://hdl.handle.net/10261/147577 | DOI: | 10.1103/PhysRevA.92.043629 | Identificadores: | doi: 10.1103/PhysRevA.92.043629 issn: 2469-9926 e-issn: 2469-9934 |
