New quantum effects in relativistic magnetohydrodynamics
Chiral anomaly induces a new kind of macroscopic quantum behavior in
relativistic magnetohydrodynamics, including the chiral magnetic effect. In
this talk we present two new quantum effects present in fluids that contain
charged chiral fermions: 1) the turbulent inverse cascade driven by the chiral
anomaly; 2) quantized chiral magnetic current induced by the reconnections of
magnetic flux. We also discuss the implications for the evolution of the
quark-gluon plasma produced in heavy ion collisions.Comment: 4 pages, 3 figures. Talk given at Quark Matter 2017 conference,

Observation of Nonlocal Modulation with Entangled Photons
We demonstrate a new type of quantum mechanical correlation where phase
modulators at distant locations, acting on the photons of an entangled pair,
interfere to determine the apparent depth of modulation. When the modulators
have the same phase, the modulation depth doubles; when oppositely phased, the
modulators negate each other.Comment: 4 pages, 4 figure
Heavy Quarkonium Dissociation Cross Sections in Relativistic Heavy-Ion Collisions
Many of the hadron-hadron cross sections required for the study of the
dynamics of matter produced in relativistic heavy-ion collisions can be
calculated using the quark-interchange model. Here we evaluate the low-energy
dissociation cross sections of , , , , and
in collision with , , and , which are important for
the interpretation of heavy-quarkonium suppression as a signature for the quark
gluon plasma. These comover dissociation processes also contribute to
heavy-quarkonium suppression, and must be understood and incorporated in
simulations of heavy-ion collisions before QGP formation can be established
through this signature.Comment: 38 pages, in LaTe
