 abstract = {The universal quantization of thermal conductance provides information
on a state's topological order. Recent measurements revealed that the
observed value of thermal conductance of the 5/2 state is inconsistent
with either Pfaftian or anti-Pfaftian model, motivating several
theoretical articles. Analysis has been made complicated by the presence
of counter-propagating edge channels arising from edge reconstruction,
an inevitable consequence of separating the dopant layer from the GaAs
quantum well and the resulting soft confining potential. Here, we
measured thermal conductance in graphene with atomically sharp confining
potential by using sensitive noise thermometry on hexagonal
boron-nitride encapsulated graphene devices, gated by either SiO2/Si or
graphite back gate. We find the quantization of thermal conductance
within 5% accuracy for nu =1;4/3;2 and 6 plateaus, emphasizing the
universality of flow of information. These graphene quantum Hall thermal
transport measurements will allow new insight into exotic systems like
even-denominator quantum Hall fractions in graphene.},
