  We investigate whether by synthesising superconductors that are tuned to a
topological, node-reconstruction transition point we could create
superconducting wires that are intrinsically resilient to quenches. Recent work
shows that the exponent characterising the temperature dependence of the
specific heat of a nodal superconductor is lowered over a region of the phase
diagram near topological transitions where nodal lines form or reconnect. Our
idea is that the resulting enhancement of the low-temperature specific heat
could have potential application in the prevention of superconductor quenches.
We perform numerical simulations of a simplified superconductor quench model.
Results show that decreasing the specific heat exponent can prevent a quench
from occurring and improve quench resilience, though in our simple model the
effects are small. Further work will be necessary to establish the practical
feasibility of this approach.
