                            - Understanding the microscopic manifestation of ergodicity-breaking and resulting metastability in disordered spin systems has been a challenge for over 40 years. We present the concept of self-sustained clusters as a driver for the emergence of slow-moving variables and computational-hardness, with potential wide-ranging implications on our ability to improve optimisation algorithms. The research, which is part of an ongoing international collaboration (Hong Kong) was funded by the Leverhulme Trust (RPG-2013-48, £155,624), published in 3 separate papers (https://doi.org/10.1103/PhysRevE.97.062154, https://doi.org/10.1103/PhysRevE.88.032132) and was presented in 6 conferences (e.g., StatPhys26, Lyon, CONES London 2016, Phase Transitions in Discrete Structures Frankfurt 2016), in two by invitation.
