Role of electron-electron and electron-phonon interaction effect in the optical conductivity of VO2 [PDF]

open access: yes, 2006
We have investigated the charge dynamics of VO2 by optical reflectivity measurements. Optical conductivity clearly shows a metal-insulator transition. In the metallic phase, a broad Drude-like structure is observed.

Phase structure of twisted Eguchi-Kawai model [PDF]

open access: yes, 2007
We study the phase structure of the four-dimensional twisted Eguchi-Kawai model using numerical simulations. This model is an effective tool for studying SU(N) gauge theory in the large-N limit and provides a nonperturbative formulation of the gauge ...

Enhanced piezoelectric properties and temperature stability in KNN-based textured ceramics

open access: yesJournal of Advanced Dielectrics, 2022
Considering the advantages of high Curie temperature and environment-friendly nature of KNN piezoelectric ceramics, the limitation of weak piezoelectric response and their temperature sensitivity to applications is worth exploring. Herein, the textured (

Morphological characterization of a polymeric microfiltration membrane by synchrotron radiation computed microtomography [PDF]

open access: yes, 2007
Most commercial polymeric membranes are prepared by phase inversion. The performance of the membranes depends greatly on the morphology of the porous structure formed during the different steps of this process.

Phase Structure of Higher Spin Black Holes [PDF]

open access: yes, 2015
We revisit the study of the phase structure of higher spin black holes carried out in arXiv$:1210.0284$ using the "canonical formalism". In particular we study the low as well as high temperature regimes.
