Universality in long-range quantum systems

Diving into the fascinating realm of quantum systems, the seminar will offer a panoramic view of long-range interactions. Starting with an encompassing tour of critical phenomena in systems featuring power-law interactions 1/𝑟𝛼 at 𝛼 < 𝑑, we’ll unveil the intricate equilibrium scaling dependence on the power-law exponent α. We will then take a deep dive into the dynamic world of “strong” long-range systems with 𝛼 < 𝑑, where we’ll unravel the counterintuitive features of out-of-equilibrium scaling dynamics during sudden and gradual quenches.
