Quantum Phase Transitions and the Breakdown of Classical General Relativity
G. Chapline, E. Hohlfeld, R. B. Laughlin +1
It is proposed that the event horizon of a black hole is a quantum phase transition of the vacuum of space-time analogous to the liquid-vapor critical point of a bose fluid. The eq…
Hidden Order in the Cuprates
S. Chakravarty, R. B. Laughlin, D. K. Morr +1
We propose that the enigmatic pseudogap phase of cuprate superconductors is characterized by a hidden broken symmetry of d(x^2-y^2)-type. The transition to this state is rounded by…
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…
