Query: Force-Induced Melting and Thermal Melting of a Double-Stranded
  Biopolymer   As a prototype of systems bearing a localization-delocalization transition,
the strand-separation (melting) process in a double-stranded biopolymer is
studied by a mapping to a quantum-mechanical problem with short-ranged
potentials. Both the bounded and the extensive eigenmodes of the corresponding
Schrodinger equation are considered and exact expressions for the
configurational partition function and free energy are obtained. The
force-induced melting is a first order phase transition process, while the
thermal melting is found to be second order. Some scaling exponents governing
thermal melting are given.
