Quantum entanglement significantly enriches states of matter at zero temperature. Quantum many-body systems with a finite spectrum gap can be roughly categorized into two different classes: (1) long range entangled states with bulk topological degeneracy (e.g. fractional quantum Hall states); (2) short range entangled (SRE) states with a trivial bulk spectrum (but they can still have protected gapless edge states), such as the integer quantum Hall states, quantum spin Hall states, topological insulators, etc.  In this talk we will discuss three subjects related to SRE states: (1) a full classification & description of bosonic SRE states with all the physically relevant symmetries; (2) a convenient and general method of diagnosing SRE states based on their bulk ground state wave functions; (3) strongly interacting fermionic SRE states and their implications on the Standard Model of particle physics.
