Phase 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 کاملMagnetic properties of interacting disordered electron systems in two dimensions
We compute the magnetic susceptibilities of interacting electrons in the presence of disorder on a twodimensional square lattice by means of quantum Monte Carlo simulations. Clear evidence is found that at sufficiently low temperatures disorder can lead to an enhancement of the ferromagnetic susceptibility. We show that it is not related to the transition from a metal to an Anderson insulator i...
متن کاملComputational study of Anticancer Dasatinib for drug delivery systems
Dasatinib is a tyrosine kinase inhibitor (TKI) that is used to treat chronic myeloid leukemia and in the management of ulcerative colitis (UC) and to provide appropriate results in treatment. Dasatinib is significantly higher and faster than full cytogenetic and large molecular responses as compared to imatinib. In the recent study, using the NMR data, the frequency and thermochemical propertie...
متن کاملCluster Monte Carlo Algorithms for Dissipative Quantum Systems
Dissipation and decoherence in quantum systems have important practical implications, from stabilizing superconductivity in granular materials, to the loss of information stored in qubits. In all the models we study, energy dissipation is introduced by coupling a quantum mechanical degree of freedom to a bath of suitably chosen harmonic oscillators. The degrees of freedom of this bath can be in...
متن کاملComputational Methods for the Measurement of Entanglement in Condensed Matter Systems
At the interface of quantum information and condensed matter physics, the study of entanglement in quantum many-body systems requires a new toolset which combines concepts from each. This thesis introduces a set of computational methods to study phases and phase transitions in lattice models of quantum systems, using the Renyi entropies as a means of quantifying entanglement. The scaling of ent...
