On the superfluidity of classical liquid in nanotubes. I: Case of even number of neutrons
The author studies the superfluidity effect in nanotubes. The authors studies the asymptotic decomposition with respect to two parameters: as \(N\rightarrow +\infty\) and as \(h\rightarrow 0\). With respect to the case studied by Bogolyubov, the presence of a potential induces the presence of quasi-particles that preserve superfluidity. Related variational equations imply the presence of running waves and of standing waves. The case studied in this paper corresponds to molecules with an odd number of neutrons. The techniques applied in the present paper combine asymptotic methods with variational tools.
