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…
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…
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…
Fractionalization in the cuprates: Detecting the topological order
T. Senthil, Matthew P. A. Fisher
The precise theoretical characterization of a fractionalized phase in spatial dimensions higher than one is through the concept of ``topological order''. We describe a physical eff…
Luttinger Liquid Physics in the Superconductor Vortex Core
Ashvin Vishwanath, T. Senthil
We study several aspects of the structure of vortices in conventional s-wave Type superconductors. It is well-known that there are low energy quasiparticles bound to the core…
