Can deeply underdoped superconducting cuprates be topological superconductors?
Yuan-Ming Lu, Tao Xiang, Dung-Hai Lee
The nodal superconducting gap is a hallmark of the cuprate high T superconductors. Surprisingly recent angle-resolved photoemission spectroscopy of deeply underdo…
Symmetry-induced anyon "breeding" in fractional quantum Hall states
Yuan-Ming Lu, Lukasz Fidkowski
An exotic feature of the fractional quantum Hall effect is the emergence of anyons, which are quasiparticle excitations with fractional statistics. In the presence of a symmetry, s…
Gapped symmetric edges of symmetry protected topological phases
Yuan-Ming Lu, Dung-Hai Lee
Symmetry protected topological (SPT) phases are gapped quantum phases which host symmetry-protected gapless edge excitations. On the other hand, the edge states can be gapped by sp…
A new collective mode in YBCO observed by time-domain reflectometry
J. P. Hinton, J. D. Koralek, Y. M. Lu +5
We report the observation of coherent oscillations associated with charge density wave (CDW) order in the underdoped cuprate superconductor YBa2Cu3O6+x by time-resolved optical ref…
Symmetry protected topological phases from decorated domain walls
Xie Chen, Yuan-Ming Lu, Ashvin Vishwanath
Symmetry protected topological (SPT) phases with unusual edge excitations can emerge in strongly interacting bosonic systems and are classified in terms of the cohomology of their…
Critical theories of phase transition between symmetry protected topological states and their relation to the gapless boundary theories
Xie Chen, Fa Wang, Yuan-Ming Lu +1
Symmetry protected topological states (SPTs) have the same symmetry and the phase transition between them are beyond Landau's symmetry breaking formalism. In this paper we study (1…
Classification and Properties of Symmetry Enriched Topological Phases: A Chern-Simons approach with applications to Z2 spin liquids
Yuan-Ming Lu, Ashvin Vishwanath
We study 2+1 dimensional phases with topological order, such as fractional quantum Hall states and gapped spin liquids, in the presence of global symmetries. Phases that share the…
