Talk Title: Deconfined local quantum criticality in the holographic approach Strongly coupled conformal field theory appears to describe universal
scaling around quantum criticality, where critical exponents reflect the nature
of emergent excitations. In particular, strong interactions can give rise to quantum
number fractionalization, resulting in enhancement of critical exponents and
well known in one dimensional correlated systems, the mechanism of which is an
interplay between correlations and topological terms. However, it is beyond the
present paradigm to confirm higher dimensional generalizations. Resorting to
the holographic approach, we claim emergence of fractionalized excitations, the
hallmark of which is enhancement of critical exponents, compared with the
absence of the topological term. Click to download: Presentation File |
