THE CONCEPTUAL BASIS OF QUANTUM FIELD THEORY
... particles is tremendously weak. As long as we disregard that, the theory is perfect. And, as I will explain, its internal logic is not shaky at all. Subatomic particles all live in the domain of physics where spins and actions are comparable to Planck’s constant h̄. One obviously needs Quantum Mecha ...

Effective Field Theory
... this does not mean that they are not important. In fact, they usually contain the interesting information about the underlying dynamics at higher scales. The point is that irrelevant operators are weak at low energies. The interactions induced by the Fermi Hamiltonian (2.9) are suppressed by two pow ...

Our bodies are made of neutrons, protons and electrons
... quarks are called Hadrons. Although individual quarks have fractional electrical charges, they combine such that hadrons have a net integer electric charge. Another property of hadrons is that they have no net color charge even though the quarks themselves carry color charge (we will try to talk mor ...

Quantum orders in an exact soluble model
... We used to believe that all phases of matter are described by Landau’s symmetry breaking theory.[1, 2] The symmetry and the related order parameters dominate our understanding of phases and phases transitions for over 50 years. In this respect, the fractional quantum Hall (FQH) states discovered in ...
