How universal is Darwin's principle?

Charles Darwin derived his principle of natural selection form observations he made in Britain and on his voyage as naturalist on board of HMS Beagle. All his conclusions were derived from studies on higher organisms, animals and plants [1], and yet the principle applies equally well to unicellular organisms, protists, eubacteria and archaebacteria. Even the evolution of viruses, viroids, and m...

How universal is the entanglement spectrum?

It is now commonly believed that the ground state entanglement spectrum (ES) exhibits universal features characteristic of a given phase. In this Letter, we show that this belief is false in general. Most significantly, we show that the entanglement Hamiltonian can undergo quantum phase transitions in which its ground state and low-energy spectrum exhibit singular changes, even when the physica...

How Universal Is the Coupling in the Sigma Model?

We calculate pion-pion scattering lengths and sigma, rho and a1 decay widths from a gauged linear sigma model with two flavours and its globally invariant generalisation.
