Noise spectroscopy and interlayer phase-coherence in bilayer quantum Hall systems
Yogesh N. Joglekar, Alexander V. Balatsky, Allan H. MacDonald
Bilayer quantum Hall systems develop strong interlayer phase-coherence when the distance between layers is comparable to the typical distance between electrons within a layer. The…
Atomic scale elastic textures coupled to electrons in superconductors
K. H. Ahn, Jian-Xin Zhu, Z. Nussinov +4
We present an atomic scale theory of lattice distortions using strain related variables and their constraint equations. Our approach connects constrained atomic length scale variat…
Nuclear spin-lattice relaxation rate in the D+iD superconducting state: implications for CoO superconductor
Yunkyu Bang, M. J. Graf, A. V. Balatsky
We calculated the nuclear spin-lattice relaxation rate for the D+iD superconducting state with impurities. We found that small amount of unitary impurities quickly produces…
in the D-wave superconducting state with coexisting antiferromagnetism
Yunkyu Bang, M. J. Graf, A. V. Balatsky +1
We consider a general D-wave superconducting gap function in the presence of coexisting antiferromagnetic (AFM) long-rang order. We find that the D-wave order parameter develops ad…
Vibration Mode Induced Shapiro Steps and Backaction in Josephson Junctions
Jian-Xin Zhu, Z. Nussinov, A. V. Balatsky
A model of a superconducting tunnel junction coupled to a mechanical oscillator is studied at zero temperature in the case of linear coupling between the oscillator and tunneling e…
Novel Spin Dynamics in a Josephson Junction
Jian-Xin Zhu, Zohar Nussinov, Alexander Shnirman +1
We address the dynamics of a single spin embedded in the tunneling barrier between two superconductors. As a consequence of pair correlations in the superconducting state, the spin…
