Departure of some parameter-dependent spectral statistics of irregular quantum graphs from Random Matrix Theory predictions (2009)

Hul, Oleh, Seba, Petr, Sirko, Leszek

Parameter-dependent statistical properties of spectra of totally connected irregular quantum graphs with Neumann boundary conditions are studied. The autocorrelation functions of level velocities...

Experimental and numerical investigation of the reflection coefficient and the distributions of Wigner's reaction matrix for irregular graphs with absorption (2009)

Lawniczak, Michal, Hul, Oleh, Bauch, Szymon, Seba, Petr, Sirko, Leszek

We present the results of experimental and numerical study of the distribution of the reflection coefficient P(R) and the distributions of the imaginary P(v) and the real P(u) parts of the Wigner's...

Experimental investigation of electric field distributions in a chaotic 3D microwave rough billiard (2009)

Tymoshchuk, Oleg, Savytskyy, Nazar, Hul, Oleh, Bauch, Szymon, Sirko, Leszek

We present the first experimental study of the electric field distributions E_N of a three-dimensional (3D) microwave chaotic rough billiard with the translational symmetry. The translational...

Investigation of nodal domains in a chaotic three-dimensional microwave rough billiard with the translational symmetry (2009)

We show that using the concept of the two-dimensional level number N_{|} one can experimentally study of the nodal domains in a three-dimensional (3D) microwave chaotic rough billiard with the...

Investigation of nodal domains in the chaotic microwave ray-splitting rough billiard (2009)

Hul, Oleh, Savytskyy, Nazar, Tymoshchuk, Oleg, Bauch, Szymon, Sirko, Leszek

We study experimentally nodal domains of wave functions (electric field distributions) lying in the regime of Shnirelman ergodicity in the chaotic microwave half-circular ray-splitting rough...

Experimental investigation of Wigner's reaction matrix for irregular graphs with absorption (2009)

Hul, Oleh, Tymoshchuk, Oleg, Bauch, Szymon, Koch, Peter M., Sirko, Leszek

We use tetrahedral microwave networks consisting of coaxial cables and attenuators connected by T-joints to make an experimental study of Wigner's reaction K matrix for irregular graphs in the...

Experimental simulation of quantum graphs by microwave networks (2004)

Hul, Oleh, Bauch, Szymon, Pakonski, Prot, Savytskyy, Nazar, Zyczkowski, Karol, Sirko, Leszek

We present the results of experimental and theoretical study of irregular, tetrahedral microwave networks consisting of coaxial cables (annular waveguides) connected by T-joints. The spectra of the...
