Discretely guided electromagnetic effective medium (2007)
Kempa, K., Wang, X., Ren, Z. F., Naughton, M. J.
A material comprised of an array of subwavelength coaxial waveguides decomposes incident electromagnetic waves into spatially discrete wave components, propagates these components without frequency...
Li, Lu, Wang, Yayu, Naughton, M. J., Ong, N. P.
Our experiments \cite{Wang05,Li05,Wang06} persuade us that the Meissner transition at $T_c$ in hole-doped cuprates is driven by the loss of long-range phase coherence caused by singular phase...
Magnetization, Nernst effect and vorticity in the cuprates (2006)
Li, Lu, Wang, Yayu, Naughton, M. J., Komiya, Seiki, Ono, Shimpei, Ando, Yoichi, ...
Nernst and magnetization experiments reveal the existence of a large region of the cuprate phase diagram above the $T_c$ curve in which vorticity and weak diamagnetism exist without phase coherence....
Depairing field, onset temperature and the nature of the transition in cuprates (2006)
Li, Lu, Wang, Yayu, Checkelsky, J. G., Naughton, M. J., Komiya, Seiki, Ono, Shimpei, ...
The depairing (upper critical) field $H_{c2}$ in hole-doped cuprates has been inferred from magnetization curves $M$-$H$ measured by torque magnetometry in fields $H$ up to 45 T. We discuss the...
Strongly nonlinear magnetization above $T_c$ in $\rm Bi_2Sr_2CaCu_2O_{8+\delta}$ (2005)
Li, Lu, Wang, Yayu, Naughton, M. J., Ono, S., Ando, Yoichi, Ong, N. P.
Using high-resolution magnetometry we have investigated in detail the magnetization $M$ above the critical temperature $T_c$ in $\rm Bi_2Sr_2CaCu_2O_{8+\delta}$. In a broad range of temperature $T$...
Lee, I. J., Brown, S. E., Yu, W., Naughton, M. J., Chaikin, P. M.
We report simultaneous NMR and electrical transport experiments in the pressure range near the boundary of the antiferromagnetic spin density wave (SDW) insulator and the metal-lic/superconducting...
Ha, H. I., Lebed, A. G., Naughton, M. J.
We report angle-dependent magnetoresistance measurements on (TMTSF)2ClO4 that provide strong support for a new macroscopic quantum phenomenon, the interference commensurate (IC) effect, in quasi-one...
Wang, Yayu, Li, Lu, Naughton, M. J., Gu, G. D., Uchida, S., Ong, N. P.
In hole-doped cuprates, Nernst experiments imply that the superconducting state is destroyed by spontaneous creation of vortices which destroy phase coherence. Using torque magnetometry on $\rm...
Angular Magnetoresistance Oscillations in Organic Conductors (2004)
Lebed, A. G., Ha, Heon-Ick, Naughton, M. J.
We demonstrate that electron wave functions change their dimensionality at some commensurate directions of a magnetic field in conductors with open [quasi-one-dimensional (Q1D)] sheets of Fermi...
Magic Angle Effects and AMRO as Dimensional Crossovers (2004)
Lebed, A. G., Bagmet, N. N., Naughton, M. J.
It is shown that interference effects between velocity and density of states, which occur as electrons move along open orbits in the extended Brillouin zone, result in a change of wave functions...
Magnetic Determination of $H_{c2}$ under Accurate Alignment in (TMTSF)$_2$ClO$_4$ (2004)
Cantilever magnetometry has been used to measure the upper critical magnetic field $H_{c2}$ of the quasi-one dimensional molecular organic superconductor (TMTSF)$_2$ClO$_4$. From simultaneous...
Interference Commensurate Oscillations in Q1D Conductors (2003)
We suggest an analytical theory to describe angular magnetic oscillations recently discovered in quasi-one-dimensional conductor (TMTSF)2PF6 [see Phys. Rev. B, 57, 7423 (1998)] and define the...
Evidence from $^{77}$Se Knight shifts for triplet superconductivity in (TMTSF)$_2$PF$_6$ (2000)
Lee, I. J., Chow, D. S., Clark, W. G., Strouse, J., Naughton, M. J., Chaikin, P. M., ...
The layered quasi-one-dimensional molecular superconductor (TMTSF)$_2$PF$_6$ is a very exotic material with a superconducting order parameter whose ground state symmetry has remained ill-defined....
Modification of activity level through biofeedback and operant conditioning.
Schulman, J L, Stevens, T M, Suran, B G, Kupst, M J, Naughton, M J
The biomotometer, an electronic device that simultaneously measures activity and provides auditory feedback to the subject, was used in combination with material reinforcers in two experiments...
Demography of penetrating cardiac trauma.
Naughton, M J, Brissie, R M, Bessey, P Q, McEachern, M M, Donald, J M, Laws, H L
All cases of penetrating cardiac trauma in 1985 and 1986 in Jefferson County, Alabama, where patients dying of penetrating trauma received autopsies, were retrospectively reviewed. All hospitals in...
