Effect of Particle-Hole Asymmetry on the Mott-Hubbard Metal-Insulator Transition

, 2004
The Mott-Hubbard metal-insulator transition is one of the most important problems in correlated electron systems. In the past decade, much progress has been made on examining a particle-hole symmetric form of the transition in the Hubbard model with ...

Metallic Janus and Patchy Particles

Particle & Particle Systems Characterization, 2012
AbstractThe concepts of Janus and patchy particles are relatively new in nanoscience. Much effort has been made during recent years to devise and fabricate asymmetric particles with multiple compositions and functionalities due to their interesting properties and potential applications in a variety of fields such as catalysis, optical imaging, or drug ...

Non-monotonic pseudo-gap in high-Tc cuprates

, 2008
The mechanism of high temperature superconductivity is not resolved for so long because the normal state of cuprates is not yet understood. Here we show that the normal state pseudo-gap exhibits an unexpected non-monotonic temperature dependence, which ...

Investigating the Effect of Metal Particles and Air Gap Defects on the Surface Charge Distribution of Epoxy Resin Using a Modified Capacitive Probe

IEEE Access
Metal particle and air gap defects on the surface of insulators can induce localized electric field distortions and exacerbate charge accumulation, subsequently triggering surface flashover.

Granulometric distribution of metals in road-deposited sediments by using different sieving methods

Environmental Advances, 2021
Road-deposited sediments (RDS) contain metals that can pollute receiving waters during precipitation events. The concentration of particle-bound metals tends to increase with decreasing particle size.

Mathematical model predicts the elastic behavior of composite materials

Materials Research, 2005
Several studies have found that the non-uniform distribution of reinforcing elements in a composite material can markedly influence its characteristics of elastic and plastic deformation and that a composite's overall response is influenced by the ...

Metal Nanoparticles as Free-Floating Electrodes

Encyclopedia, 2021
Colloidal metal nanoparticles in an electrolyte environment are not only electrically charged but also electrochemically active objects. They have the typical character of metal electrodes with ongoing charge transfer processes on the metal/liquid ...

Casimir repulsion between metallic objects in vacuum

, 2010
We give an example of a geometry in which two metallic objects in vacuum experience a repulsive Casimir force. The geometry consists of an elongated metal particle centered above a metal plate with a hole.

Efficient Slave-Boson Approach for Multiorbital Two-Particle Response Functions and Superconductivity

Physical Review X, 2021
We develop an efficient approach for computing two-particle response functions and interaction vertices for multiorbital strongly correlated systems based on the rotationally invariant slave-boson framework.
