Signature of a topological phase transition in the Josephson supercurrent through a topological insulator
Vladimir Orlyanchik, Martin P. Stehno, Christopher D. Nugroho +5
Topological insulators (TIs) hold great promise for realizing zero-energy Majorana states in solid-state systems. Recently, several groups reported experimental data suggesting tha…
Low frequency resistance and critical current fluctuations in Al-based Josephson junctions
C. D. Nugroho, V. Orlyanchik, D. J. Van Harlingen
We present low-temperature measurements of the low-frequency noise arising from an ensemble of two-level fluctuators in the oxide barrier of Al/AlO/Al Josephson junctio…
Anomalous Noise in the Pseudogap Regime of YBaCuO
D. S. Caplan, V. Orlyanchik, M. B. Weissman +4
An unusual noise component is found near and below about 250 K in the normal state of underdoped YBCO and Ca-YBCO films. This noise regime, unlike the more typical noise above 250…
The Electron-Glass in samples approaching the Mesoscopic regime
V. Orlyanchik, Z. Ovadyahu
We study the dependence of the glassy properties of strongly localized indium-oxide films on the sample lateral dimensions. Characteristic mesoscopic effects such as reproducible c…
Non-Gaussian conductance noise in disordered electronic systems due to a non-linear mechanism
V. Orlyanchik, V. I. Kozub, Z. Ovadyahu
We present results of conductance-noise experiments on disordered films of crystalline indium oxide with lateral dimensions 2microns to 1mm. The power-spectrum of the noise has the…
Conductance noise in interacting Anderson insulators driven far from equilibrium
V. Orlyanchik, Z. Ovadyahu
The combination of strong disorder and many-body interactions in Anderson insulators lead to a variety of intriguing non-equilibrium transport phenomena. These include slow relaxat…
