Correlations among the Riemann zeros: Invariance, resurgence, prophecy and self-duality
W. T. Lu, S. Sridhar
We present a conjecture describing new long range correlations among the Riemann zeros leading to 3 principal features: (i) The spectral auto-correlation is invariant w.r.t. the av…
Refraction of Electromagnetic Energy for Wave Packets Incident on a Negative Index Medium is Always Negative
W. T. Lu, J. B. Sokoloff, S. Sridhar
We analyze refraction of electromagnetic wave packets on passing from an isotropic positive to an isotropic negative refractive index medium. We definitively show that in all cases…
Fractal Weyl laws for chaotic open systems
W. T. Lu, S. Sridhar, Maciej Zworski
We present a result relating the density of quantum resonances for an open chaotic system to the fractal dimension of the associated classical repeller. The result is supported by…
Sinai billiards, Ruelle zeta-functions and Ruelle resonances: microwave experiments
S. Sridhar, W. T. Lu
We discuss the impact of recent developments in the theory of chaotic dynamical systems, particularly the results of Sinai and Ruelle, on microwave experiments designed to study qu…
Dielectric signatures of lattice instabilities at 32K and 245K in (M=Cu,Ni) Cuprates and Nickelates
P. V. Parimi, N. Hakim, F. C. Chou +2
New dielectric transitions are observed at common temperatures 32K and 245K, in isostructural and that are signatures of local lattice…
rf susceptibility of La_{1-x}Sr_{x}MnO_{3} single crystals : magnetic signatures of structural changes
P. V. Parimi, H. Srikanth, M. Bailleul +4
A sensitive tunnel diode oscillator (TDO) operating at 4MHz is used to probe the dynamic response of La_{1-x}Sr_{x}MnO_{3} single crystals for x=0.125,0.175,0.28 and 0.33 doping. S…
