Emergent low-energy bound states in the two-orbital Hubbard model [PDF]

, 2018
A repulsive Coulomb interaction between electrons in different orbitals in correlated materials can give rise to bound quasiparticle states. We study the nonhybridized two-orbital Hubbard model with intra- (inter)orbital interaction U(U12) and different ...

Solving the multi-site and multi-orbital Dynamical Mean Field Theory using Density Matrix Renormalization [PDF]

, 2017
We implement an efficient numerical method to calculate response functions of complex impurities based on the Density Matrix Renormalization Group (DMRG) and use it as the impurity-solver of the Dynamical Mean Field Theory (DMFT).

Electron emission in collisions between dressed Alq+ ions with He targets [PDF]

, 2013
Experimental and theoretical results are presented for electron emission in collisions between dressed Alq+ ions and atomic He targets. The experimental data are compared with a four-body CTMC model and two distorted wave models, namely the CDW and CDW ...

Long-term prognostic implications of type 2 diabetes mellitus in colorectal cancer patients. [PDF]

Colorectal Dis
Abstract Aim Colorectal cancer (CRC) is one of the most prevalent cancers worldwide. Epidemiological evidence has identified Type 2 Diabetes Mellitus (T2DM) as a risk factor for CRC. This study aimed to evaluate the impact of T2DM, along with clinicopathological and socio‐demographic factors, on long‐term overall survival in a large, nationally ...

Effects of noise on the internal resonance of a nonlinear oscillator [PDF]

, 2018
We numerically analyze the response to noise of a system formed by two coupled mechanical oscillators, one of them having Duffing and van der Pol nonlinearities, and being excited by a self-sustaining force proportional to its own velocity.
