Fluctuations, dissipation, and nonuniversal superfluid jumps in two-dimensional superconductors
R. W. Crane, N. P. Armitage, A. Johansson +3
We report a comprehensive study of the complex AC conductivity of thin effectively 2D amorphous superconducting InO_x films at zero applied field. Below a temperature scale T_c0 wh…
Survival of superconducting correlations across the 2D superconductor-insulator transition: A finite frequency study
R. W. Crane, N. P. Armitage, A. Johansson +3
The complex ac conductivity of thin highly disordered InOx films was studied as a function of magnetic field through the nominal two-dimensional superconductor-insulator transition…
Charge Transfer and Charge Transport on the Double Helix
N. P. Armitage, M. Briman, G. Gruner
We present a short review of various experiments that measure charge transfer and charge transport in DNA. Some general comments are made on the possible connection between 'chemis…
Duplex-single strand denaturing transition in DNA oligomers
G. Zocchi, A. Omerzu, T. Kuriabova +2
We have measured the temperature driven denaturing, or melting transition in poly d(A)-poly d(T) DNA oligomers of various lengths in different buffer conditions. Our findings are i…
Dipole relaxation losses in DNA
M. Briman, N. P. Armitage, E. Helgren +1
The electrodynamic response of DNA in the millimeter wave range is investigated. By performing measurements under a wide range of humidity conditions and comparing the response of…
The Nature of Heavy Quasiparticles in Magnetically Ordered Heavy Fermions
M. Dressel, N. Kasper, K. Petukhov +4
The optical conductivity of the heavy fermions UPd2Al3 and UPt3 has been measured in the frequency range from 10 GHz to 1.2 THz (0.04 meV to 5 meV) at temperatures 1 K < T < 300 K.…
