Tuning the universality class of quantum spin chains

In the introductory solid state physics courses, lattice vibrations in a crystal are typically introduced by considering first a hypothetical one-dimensional chain of atoms, which can be solved fully making it easier to grasp the idea of phonons (quanta of lattice waves) without really worrying about the complexities of a real three-dimensional crystal. The ditto … Continue reading

A Critique of Niche Construction Theory

In a recent article, Dr.¬†Sutirth¬†Dey from IISER Pune, along with researchers from JNCASR, Bangalore and IISER Mohali, have critically analysed the literature on the idea of niche construction (NC) in evolutionary biology and have questioned several claims of the proponents of NC. Niche construction refers to the phenomenon where changes to the environment caused by … Continue reading
