Upconversion of terahertz phonons in spin-ladder compounds via nonlinear coupling

S. J. Sreerag, N. Malathi, Shahla Yasmin Mathengattil +3

We demonstrate dynamic control of the lattice by THz light by exploiting the coupling of phonon modes. The low-energy sliding phonon modes in the spin-ladder system, Sr $_{14}$ Cu$_{…

Excess speicific heat of the gapped sliding phonons in the incommensurate composite crystal Sr $_{14}$ Cu $_{24}$ O $_{41}$

Rabindranath Bag, Soumitra Hazra, R. N. Kini +1

We show that low temperature specific heat (C $_{p}$ ) of the incommensurate chain-ladder system Sr $_{14}$ Cu $_{24}$ O $_{41}$ is enriched by the presence of a rather large excess contrib…
