text: distance between particle clusters resulting from the demixing process that occurs already in the 
  
  bulk liquid and is not related to the front instability at all. Note that one ﬁnds a similar sequence 
  
  of regimes (i) to (iv) when increasing the particle-particle interaction strengths for ﬁxed εnl (see 
  
  Ref. [41]) for further details.
