We theoretically investigate collective modes of a one-dimensional (1D)interacting Bose gas in harmonic traps at finite temperatures, by using avariational approach and local density approximation. We find that thetemperature dependence of collective mode frequencies is notably different inthe weakly and strongly interacting regimes. Therefore, the experimentalmeasurement of collective modes could provide a sensitive probe for differentquantum phases of a 1D trapped Bose gas, realized by tuning the interatomicinteraction strength and temperature. Our prediction on the temperaturedependence of the breathing mode frequency is in good qualitative agreementwith an earlier experimental measurement for a weakly interacting 1D Bose gasof rubidium-87 atoms in harmonic traps [Moritz et al., Phys. Rev. Lett. 91,250402 (2003)].
