Spin Transport in Quantum Spin-Orbital Liquids
Zekun Zhuang, J. B. Marston
Quantum spin-orbital liquids (QSOLs) are a novel phase of matter, similar to quantum spin liquids, with quantum fluctuations in both spin and orbital degrees of freedom. We use non…
Resistively detected NMR as a probe of the topological nature of conducting edge/surface states
Zekun Zhuang, V. F. Mitrović, J. B. Marston
Electron spins in edge or surface modes of topological insulators (TIs) with strong spin-orbit coupling cannot be directly manipulated with microwaves due to the locking of electro…
Transport in Conductors and Rectifiers: Mean-Field Redfield Equations and Non-Equilibrium Green's Functions
Zekun Zhuang, Jaime Merino, J. B. Marston
We derive a closed equation of motion for the one particle density matrix of a quantum system coupled to multiple baths using the Redfield master equation combined with a mean-fiel…
Topological Origin of Equatorial Waves
Pierre Delplace, J. B. Marston, Antoine Venaille
Topology sheds new light on the emergence of unidirectional edge waves in a variety of physical systems, from condensed matter to artificial lattices. Waves observed in geophysical…
Energy and Charge Transfer for Na+ Ions Scattered from a Ag(001) Surface
M. P. Ray, R. E. Lake, J. B. Marston +1
We present energy- and charge-resolved measurements of low and hyperthermal energy Na+ ions scattered from a Ag(001) surface. With the primary ion beam oriented along the [110] cry…
Rectification in one--dimensional electronic systems
Bernd Braunecker, D. E. Feldman, J. B. Marston
Asymmetric current--voltage () curves, known as the diode or rectification effect, in one--dimensional electronic conductors can have their origin from scattering off a singl…
Response to ``Comment on `time-dependent density-matrix renormalization group: a systematic method for the study of quantum many-body out-of-equilibrium systems''' by H. G. Luo, T. Xiang, and X. Q. Wang
M. A. Cazalilla, J. B. Marston
Reply to the Comment of Luo, Xiang, and Wang, cond-mat/0212580.
Time-dependent density-matrix renormalization group: A systematic method for the study of quantum many-body systems out-of-equilibrium
M. A. Cazalilla, J. B. Marston
The density-matrix renormalization-group (DMRG) algorithm is extended to treat time-dependent problems. The method provides a systematic and robust tool to explore out-of-equilibri…
Study of critical behavior of the supersymmetric spin chain that models plateau transitions in the integer quantum Hall effect
Shan-Wen Tsai, J. B. Marston
We use the density-matrix renormalization-group (DMRG) algorithm and finite-size scaling to study a supersymmetric (SUSY) spin chain that models plateau transitions in the integer…
The Chalker-Coddington Network Model is Quantum Critical
J. B. Marston, Shan-Wen Tsai
We show that the localization transition in the integer quantum Hall effect as described by the Chalker-Coddington network model is quantum critical. We first map the anisotropic n…
Supersymmetry and Localization in the Quantum Hall Effect
J. Kondev, J. B. Marston
We study the localization transition in the integer quantum Hall effect as described by the network model of quantum percolation. Starting from a path integral representation of tr…
