James David Ebert (1921-2001)
James David Ebert studied the developmental processes of chicks and of viruses in the US during the twentieth century. He also helped build and grow many research institutions, such as the Department of Embryology in the Carnegie Institution of Washington [5] in Baltimore, Maryland and the Marine Biological Laboratory [6] (MBL) in Woods Hole [7], Massachusetts. When few biologists studied the b...
متن کاملProfile of David J. Thouless, J. Michael Kosterlitz, and F. Duncan M. Haldane, 2016 Nobel Laureates in Physics.
One of the most profound and mysterious facts in science is that abstract mathematics can beautifully describe various phenomena realized in the real world. The deep connection between geometry and physics, which dates back to ancientGreece, continues to surprise us and most remarkably has borne fruit as general relativity. Topology is a branch of geometry, where two objects are congruent if on...
متن کاملRevisiting Thouless conductance formula
It was shown using perturbation theory[1] that Thouless energy Ec for a quantum system scales linearly with the conductance of the system. We derive in an alternate way in 1-D that Ec scales with the conductance in a very different way. We physically show the difference between our approach and that of ref. 1 to expect our results to hold in higher dimensions also. We verify our results with ex...
متن کاملThe Kosterlitz-Thouless Transition
Matter in the universe is organised in a hierarchical structure. At the bottom we have elementary particles: quarks, gluons, electrons etc. At present we don’t know what these particles are made off. But we believe we know that quarks, gluons etc. make up protons, neutrons, etc. These then go together to make atoms, that are the building blocks of molecules. Atoms and molecules gives us gas, li...
متن کاملThe Kosterlitz–thouless Universality Class
We examine the Kosterlitz–Thouless universality class and show that conventional (essential) scaling at this type of phase transition is self–consistent only if modified by multiplicative logarithmic corrections. In the case of specific heat these logarithmic corrections are identified analytically. To identify those corresponding to the susceptibility we set up a numerical method involving the...
