Exact thermal properties of free-fermionic spin chains
Michał Białończyk, Fernando Javier Gómez-Ruiz, Adolfo del Campo
An exact description of integrable spin chains at finite temperature is provided using an elementary algebraic approach in the complete Hilbert space of the system. We focus on spi…

Full Counting Statistics of Topological Defects After Crossing a Phase Transition
Fernando J. Gómez-Ruiz, Jack J. Mayo, Adolfo del Campo
We consider the number distribution of topological defects resulting from the finite-time crossing of a continuous phase transition and identify signatures of universality beyond t…

Experimentally testing quantum critical dynamics beyond the Kibble-Zurek mechanism
Jin-Ming Cui, Fernando Javier Gómez-Ruiz, Yun-Feng Huang +3
We experimentally probe the distribution of kink pairs resulting from driving a one-dimensional quantum Ising chain through the paramagnet-ferromagnet quantum phase transition, usi…
