Novel coexisting density wave ground state in strongly correlated, two-dimensional electronic materials
S. Mazumdar, R. T. Clay, D. K. Campbell
Two-dimensional (2D) strongly correlated electron systems underlie many of the most important phenomena in contemporary condensed matter physics, including the Quantum Hall Effect…
Dynamics of the Measurement of Nuclear Spins in a Solid-State Quantum Computer
Gennady P. Berman, David K. Campbell, Gary D. Doolen +1
We study numerically the process of nuclear spin measurement in a solid-state quantum computer of the type proposed by Kane by modeling the quantum dynamics of two coupled nuclear…
Spin-Peierls transition in the Heisenberg chain with finite-frequency phonons
Anders W. Sandvik, David K. Campbell
We study the spin-Peierls transition in a Heisenberg spin chain coupled to optical bond-phonons. Quantum Monte Carlo results for systems with up to N=256 spins show unambiguously t…
Andreev reflections in the pseudogap state of cuprate supercondcutors
Han-Yong Choi, Yunkyu Bang, David K. Campbell
We propose that, if the pseudogap state in the cuprate superconductors can be described in terms of the phase-incoherent preformed pairs, there should exist Andreev reflection from…
