Monopole Condensation in Lattice SU(2) QCD [PDF]

open access: yes, 1995
This is the short review of Monte-Carlo studies of quark confinement in lattice QCD. After abelian projections both in the maximally abelian and Polyakov gauges, it is seen that the monopole part alone is responsible for confinement.

Quantum and Dielectric Confinement Effects in Lower-Dimensional Hybrid Perovskite Semiconductors.

open access: yesChemical Reviews, 2019
Hybrid halide perovskites are now superstar materials leading the field of low-cost thin film photovoltaics technologies. Following the surge for more efficient and stable 3D bulk alloys, multilayered halide perovskites and colloidal perovskite ...

Rate effects on layering of a confined linear alkane [PDF]

open access: yesPhys Rev Lett 99 (2007) 225503, 2007
We perform drainage experiments of a linear alkane fluid (n-hexadecane) down to molecular thicknesses, and focus on the role played by the confinement rate. We show that molecular layering is strongly influenced by the velocity at which the confining walls are approached: under high enough shear rates, the confined medium behaves as a structureless ...

Positive and Negative Changes in Food Habits, Physical Activity Patterns, and Weight Status during COVID-19 Confinement: Associated Factors in the Chilean Population

open access: yesInternational Journal of Environmental Research and Public Health, 2020
The association between the changes in lifestyle during coronavirus disease 2019 (COVID-19) confinement and body weight have not been studied deeply. Therefore, the aim of the present study was to determine lifestyle changes, such as eating habits and ...

Spatial confinement effects on quantum field theory using nonlinear coherent states approach [PDF]

open access: yesJ.Phys.A42:045403,2009, 2007
We study some basic quantum confinement effects through investigation a deformed harmonic oscillator algebra. We show that spatial confinement effects on a quantum harmonic oscillator can be represented by a deformation function within the framework of nonlinear coherent states theory.

3D confinement of water: H2O exhibits long-range (> 50 nm) structure while D2O does not [PDF]

open access: yes, 2022
Water is the liquid of life, thanks to its three-dimensional adaptive hydrogen (H)-bond network. Confinement of this network may lead to dramatic structural changes that influence chemical and physical transformations. Although confinement effects occur on a < 1 nm length scale, the upper length scale limit is not known.

Experimental and numerical modeling of plasma start-up assisted by electron drift injection on J-TEXT

open access: yesNuclear Fusion, 2023
Start-up is one of the critical phases for tokamak discharge. The electron drift injection (EDI) system has been developed on J-TEXT for start-up studies.

Cinema of Confinement [PDF]

open access: yes, 2019
In this book, Thomas J. Connelly draws on a number of key psychoanalytic concepts from the works of Jacques Lacan, Slavoj Žižek, Joan Copjec, Michel Chion, and Todd McGowan to identify and describe a genre of cinema characterized by spatial confinement.

Physical and Psychological Effects Related to Food Habits and Lifestyle Changes Derived from COVID-19 Home Confinement in the Spanish Population

open access: yesNutrients, 2020
As a consequence of COVID-19, millions of households have suffered mobility restrictions and changes in their lifestyle over several months. The aim of this study is to evaluate the effects of COVID-19 home confinement on the food habits, lifestyle and ...
