Webb6. Phase Transitions ¶. As you change the macroscopic variables of a system, sometimes its properties will abruptly change, often in a dramatic way. For example, it might change from a solid to a liquid, or from a liquid to a gas. These are examples of phase transitions. The goal of this chapter is to understand why phase transitions happen ...

Webb6 juni 2024 · In 1973, Halperin, Lubensky and Ma showed that the fluctuations of the gauge field actually drive the phase transition to become first-order. This is called fluctuation … Webb14 juli 2016 · An interesting feature of the system is that it undergoes first-order phase transitions in both the microcanonical and canonical ensembles. Using the Landau theory of phase transitions, below we study the critical points in the two ensembles and show explicitly that they differ from each other.

This basic observation begins to explain why it's so hard in practice to distinguish between a continuous and discontinuous phase transition, since it just comes down to a sign of one phenomenological parameter.

WebbThe phase structure of ABJM theory with mass m deformation and non-vanishing Fayet-Iliopoulos (FI) parameter, zeta, is studied through the use of localisation on S-3. The partition function of the theory then reduces to a matrix integral, which, in the large N limit and at large sphere radius, is exactly computed by a saddle-point approximation. When …
