New theory links quantum geometry to electron-phonon coupling
A new study published in Nature Physics introduces a theory of electron-phonon coupling that is affected by the quantum geometry of the electronic wavefunctions.

In dim light a cat sees much better than you do, as do dogs and nocturnal animals. That's because the structure of a cat's eye has a tapetum lucidum, a mirror-like layer immediately behind the retina. Light entering the eye ...
Shape-memory polymers or shape-shifting materials are smart materials that have gained significant attention within materials science and biomedical engineering in recent years to build smart structures and devices. Digital ...
Seas, oceans, rivers, and other bodies of water on Earth have become increasingly polluted over the past decades, and this is threatening the survival of many aquatic species. This pollution takes a wide range of forms, including ...
A team of scientists, led by Dr. David Hsieh from the California Institute of Technology, have observed evidence of stable Hubbard excitons in a photo-doped antiferromagnetic Mott insulator. The findings of their study are ...
Mott insulators are a peculiar class of materials with structures that should theoretically conduct electricity, but that are instead insulators. These materials contain strongly correlated electrons, which can generate highly ...
Over the past few decades, material scientists and chemists have been working on designing increasingly sophisticated materials for a wide range of technological and scientific applications. These materials include synthetic ...
Materials scientists aim to develop autonomous materials that function beyond stimulus responsive actuation. In a new report in Science Advances, Yang Yang and a research team in the Center for Bioinspired Energy Science ...
Merons, topological structures based on in-plane magnetized magnetic materials, could have numerous valuable applications, particularly for carrying information or storing magnetic charge. Most past realizations of these ...
Genetic diversity is essential to the survival of a species. It's easy enough to maintain if a species reproduces sexually; an egg and a sperm combine genetic material from two creatures into one, forming a genomically robust ...

In philosophy, the theory of materialism holds that the only thing that exists is matter; that all things are composed of material and all phenomena (including consciousness) are the result of material interactions. In other words, matter is the only substance. To many philosophers, not only is 'physicalism' synonymous with 'materialism', but they use both words to describe a position that supports ideas from physics which may not be matter in the traditional sense (like anti-matter or gravity). Therefore much of the generally philosophical discussion below on materialism may be relevant to physicalism. Also related are the ideas of methodological naturalism (i.e. "let's at least do science as though physicalism is true") and metaphysical naturalism (i.e. "philosophy and science should operate according to the physical world, and that's all that exists"). The philosophical alternatives to materialism are some forms of monism (besides the materialistic monism), dualism and idealism.
