Quantum phase transitions and Fermi liquid theory

2 Phase Transitions in Quantum Field Theory

In this lecture at a school for condensed matter physicist, I begin with basic concepts and tools for investigating phase transitions in quantum field theory. The very different roles of global and gauge symmetries in phase transitions will be elucidated. Among the important applications of the basic theory the thermodynamics of the electroweak transition is treated in detail, and the implicati...

Baryon Mass and Phase Transitions in Large N Gauge Theory

We calculate baryon mass inN = 4 largeN gauge theory by means of AdS/CFT correspondence, and find that phase transitions occur when temperature or theta angle takes a critical value. Furthermore, we find there are bound states of Wbosons in Higgs phase.

String theory, quantum phase transitions, and the emergent Fermi liquid.

A central problem in quantum condensed matter physics is the critical theory governing the zero-temperature quantum phase transition between strongly renormalized Fermi liquids as found in heavy fermion intermetallics and possibly in high-critical temperature superconductors. We found that the mathematics of string theory is capable of describing such fermionic quantum critical states. Using th...

Phase Transitions and Quantum Measurements

In a quantum measurement, a coupling g between the system S and the apparatus A triggers the establishment of correlations, which provide statistical information about S. Robust registration requires A to be macroscopic, and a dynamical symmetry breaking of A governed by S allows the absence of any bias. Phase transitions are thus a paradigm for quantum measurement apparatuses, with the order p...
