Coordinate Representation of the Two-Spinon wavefunction and Spinon Interaction
B. A. Bernevig, D. Giuliano, R. B. Laughlin
By deriving and studying the coordinate representation for the two-spinon wavefunction, we show that spinon excitations in the Haldane-Shastry model interact. The interaction is gi…
Spinon Attraction in Spin-1/2 Antiferromagnetic Chains
B. A. Bernevig, D. Giuliano, R. B. Laughlin
We derive the representation of the two-spinon wavefunction for the Haldane-Shastry model in terms of the spinon coordinates. This result allows us to rigorously analyze spinon int…
How Bob Laughlin Tamed the Giant Graviton from Taub-NUT space
B. A. Bernevig, J. Brodie, L. Susskind +1
In this paper we show how two dimensional electron systems can be modeled by strings interacting with D-branes. The dualities of string theory allow several descriptions of the sys…
Spectroscopy of Matter Near Criticality
B. A. Bernevig, D. Giuliano, R. B. Laughlin
We propose that the finite-frequency susceptibility of matter near a class of zero-temperature phase transition exhibits distinctive excitonic structure similar to meson resonances…
