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, SrCu$_{…
Long-Lived Coherent Acoustic Phonons in Epitaxially Grown III-V Adiabatic Cavities
Muhammad Hanif, Milos Dubajic, Sandeep. J. Sreerag +4
We provide evidence of strongly confined coherent acoustic phonons inside high quality factor phononic cavities that exhibit tailoredphonon potentials. Using GaAs/AlAs quasiperiodi…
Excess speicific heat of the gapped sliding phonons in the incommensurate composite crystal SrCuO
Rabindranath Bag, Soumitra Hazra, R. N. Kini +1
We show that low temperature specific heat (C) of the incommensurate chain-ladder system SrCuO is enriched by the presence of a rather large excess contrib…
Dynamics of Photo-excited Spins in InSb Based Quantum Wells
K. Nontapot, R. N. Kini, B. Spencer +5
We report time resolved measurements of spin relaxation in doped and undoped InSb quantum wells using degenerate and two-color magneto-optical Kerr effect techniques. We observed t…
