In […]

How do they manifest in the dual […]

Moreover, a superfluid soliton is itself unstable, which leads to interesting non-equilibrium physics, like dynamic phase transition. I will introduce those aspects […]

When strong coupling phenomena take place, important lessons can be learned by resorting […]

We show that this question can be answered within semi-classical gravity. […]

Crucially, the central charge obeys the c-theorem, a powerful, universal, non-perturbative constraint: the central charge must decrease […]

Polytechnique) Link: https://zoom.us/j/98260147834?pwd=VW5BQStqUGUrUFFzWG1jL2tuWXJoZz09 Title: Damping of pseudo-Goldstone bosons Abstract:  When a continuous symmetry is spontaneously broken, new gapless modes appear in the spectrum, the Goldstone bosons. A weak explicit breaking of the same symmetry generates a small mass for the Goldstones, now called pseudo-Goldstones. On […]

This non-equilibrium coset construction makes significant advances beyond more standard coset […]

In order to […]
