Critical Dynamics of Thermal Conductivity at the Normal-Superconducting Transition
Smitha Vishveshwara, Matthew P. A. Fisher
We study the effect of thermal fluctuations on the critical dynamics of the three-dimensional disordered superconductor across the normal-superconducting transition. We employ a ph…
Detecting fractions of electrons in the high- cuprates
T. Senthil, Matthew P. A. Fisher
We propose several tests of the idea that the electron is fractionalized in the underdoped and undoped cuprates. These include the ac Josephson effect, and tunneling into small sup…
Measuring Fractional Charge in Carbon Nanotubes
Cristina Bena, Smitha Vishveshwara, Leon Balents +1
The Luttinger model of the one-dimensional Fermi gas is the cornerstone of modern understanding of interacting electrons in one dimension. In fact, the enormous class of systems wh…
Fractionalization, topological order, and cuprate superconductivity
T. Senthil, Matthew P. A. Fisher
This paper is concerned with the idea that the electron is fractionalized in the cuprate high- materials. We show how the notion of topological order may be used to develop a…
Quantum Confinement Transition in a d-wave Superconductor
C. Lannert, Matthew P. A. Fisher, T. Senthil
We study the nature of the zero-temperature phase transition between a d-wave superconductor and a Mott insulator in two dimensions. In this ``quantum confinement transition'', spi…
Fractionalization and confinement in the U(1) and gauge theories of strongly correlated systems
T. Senthil, Matthew P. A. Fisher
Recently, we have elucidated the physics of electron fractionalization in strongly interacting electron systems using a gauge theory formulation. Here we discuss the connecti…
Quasiparticle Localization Transition in Dirty Superconductors
Smitha Vishveshwara, Matthew P. A. Fisher
In this paper, a delocalization-localization transition within the superconducting state is explored. The symmetries of the Bogoliubov deGennes Hamiltonian endow the two associated…
Non-linear Transport in Quantum-Hall Smectics
A. H. MacDonald, Matthew P. A. Fisher
Recent transport experiments have established that two-dimensional electron systems with high-index partial Landau level filling, , have ground states w…
