Quantum phase transition discovered in a quasi-2D system consisting purely of spins
Pure quantum systems can undergo phase transitions analogous to the classical phase transition between the liquid and gaseous states of water. At the quantum level, however, the particle spins in states that emerge from phase transitions display coll.....»»
Omitting delays from outbreak models grossly underestimates epidemic severity
For livestock diseases, like foot-and-mouth disease (FMD) and swine flu, rapid culling and carcass disposal are well-established strategies for halting an outbreak and limiting its impact. However, even when infection is quickly detected delays in th.....»»
