Ordered phases in the extended Hubbard model
(Elsevier B.V., 1994-04-02)
A novel method to probe the diverse phases for the extended Hubbard model (EHM), including the correlated hopping term, is presented. We extend an effective medium approach [1] to a bipartite lattice, allowing for charge- ...
Determination of the Forming-Limit Diagram from Deformations within Necking Instability: A Digital Image Correlation-Based Approach
(Springer, 2020-06)
It is now possible using digital-image correlation techniques to precisely measure deformation within a developing necking instability, during forming-limit experiments. However, the current standards for measuring limit ...
Evaluation of particle-anti-particle scaled correlation within effective models
(Elsevier B.V., 2020-02-01)
Correlations and fluctuations of physical quantities are known to play an important role in phase transitions and critical phenomena. In recent years some experimental attempts were made in the scope of the Beam Energy ...
Correlation exponent K-rho of the one-dimensional Kondo lattice model

RR Lyrae Period-Amplitude Diagrams: From Bailey to Today
(2011)
More than a century ago, Solon Bailey's pioneering investigations of the variable stars in globular clusters allowed the first period-amplitude diagrams to be constructed for their RR Lyrae stars. These diagrams differ ...
Renormalization group improved computation of correlation functions in theories with nontrivial phase diagram
(2016-07-08)
We present a simple and consistent way to compute correlation functions in interacting theories with nontrivial phase diagram. As an example we show how to consistently compute the four-point function in three dimensional ...

Yang-Lee zeros of the two- and three-state Potts model defined on π3 Feynman diagrams
(Amer Physical Soc, 2003-06-01)
We present both analytical and numerical results on the position of partition function zeros on the complex magnetic field plane of the q=2 state (Ising) and the q=3 state Potts model defined on phi(3) Feynman diagrams ...
