"The Electron-Ion Collider: A collider to unravel the mysteries of visible matter," Elke Aschenauer (BNL)
"The Electron-Ion Collider: A collider to unravel the mysteries of visible matter," Elke Aschenauer (BNL)
Abstract: Understanding the properties of nuclear matter and its emergence through the underlying partonic structure and dynamics of quarks and gluons requires a new experimental facility in hadronic physics known as the Electron-Ion Collider (EIC). The EIC will address some of the most profound questions concerning the emergence of nuclear properties by precisely imaging gluons and quarks inside protons and nuclei such as their distributions in space and momentum, their role in building the nucleon spin and the properties of gluons in nuclei at high energies. This presentation will give highlights on the EIC science program, introduce the needed experimental equipment and describe the components of the EIC accelerator critical for the science program. The talk will end summarizing the status of the EIC project.
"Discover C-conjugation odd ggg exchange in exclusive χ_cJ production at the EIC," Adrian Dumitru (Baruch)
"Discover C-conjugation odd ggg exchange in exclusive χ_cJ production at the EIC," Adrian Dumitru (Baruch)
Abstract: Production of C-even quarkonium states in exclusive DIS at high energies requires the t-channel exchange of at least three gluons in a color singlet, C-odd state. The amplitude for this process is proportional to the cubic Casimir of color-SU(3) and involves the light-cone matrix element of three color currents. I present numerical predictions for the cross section and discuss the potential for discovery of the ggg exchange (and its resummed form, the "Odderon") of QCD.
"Novel hydrodynamic transport, transport far from equilibrium & magnetohydrodynamics with a view to the EIC," Matthias Kaminski (Alabama)
"Novel hydrodynamic transport, transport far from equilibrium & magnetohydrodynamics with a view to the EIC," Matthias Kaminski (Alabama)
Abstract: When chiral charged matter is exposed to extremely strong magnetic fields, novel hydrodynamic transport effects emerge. These novel effects need to be estimated and possibly taken into account, for example in the hydrodynamic codes used to analyze heavy-ion collision data or magnetars. Kubo formulae link the macroscopic transport coefficients to the microscopic retarded two-point correlation functions of conserved currents. Some among the transport effects cause no dissipation, i.e. they produce no entropy; for example, the chiral magnetic effect (CME). As a case study far away from equilibrium, the CME within holographic plasma suggests lessons for the quark-gluon-plasma at colliders. We will consider the possibilities for hydrodynamic descriptions at the EIC.

"Edge Modes and Fluid Dynamics", V.P. Nair (City College)

"Is holographic quark-gluon plasma homogeneous?" Matti Jӓrvinen (APCTP)
"Is holographic quark-gluon plasma homogeneous?" Matti Jӓrvinen (APCTP)
Abstract: The presence of Chern-Simons terms in holographic QCD is required by the global chiral anomalies. These Chern-Simons terms may give rise to a spatial instability at nonzero density, known as the Nakamura-Ooguri-Park instability. I demonstrate that this instability is unavoidable in a large class of bottom-up models of QCD anchored to lattice data, and extends to surprisingly high temperatures and low baryon number densities. The precise range of the instability is however sensitive to the strange quark mass, which is not properly included in these models so far.

"Gravitational Form Factors at the EIC", Yoshitaka Hatta (BNL)
Abstract: After giving an introduction to the physics of the gravitational form factors of hadrons, I discuss prospects for measuring them at the EIC and how they can be computed in holography and other approaches.
"Far-from-equilibrium cascades at large N", Vladimir Rosenhaus (CUNY)
"Far-from-equilibrium cascades at large N", Vladimir Rosenhaus (CUNY)
Abstract: We study wave turbulence in systems with two special properties: a large number of fields (large N) and a nonlinear interaction that is strongly local in momentum space. The first property allows us to find the kinetic equation at all interaction strengths -- both weak and strong, at leading order in 1/N. The second allows us to turn the kinetic equation -- an integral equation -- into a differential equation. We find stationary solutions for the occupation number as a function of wave number, valid at all scales. As expected, on the weak coupling end the solutions asymptote to Kolmogorov-Zakharov scaling. On the strong coupling end, they asymptote to either the widely conjectured generalized Phillips spectrum (also known as critical balance), or a Kolmogorov-like scaling exponent.
"Floquet insulators and lattice fermions", Srimoyee Sen (Iowa State)
"Floquet insulators and lattice fermions", Srimoyee Sen (Iowa State)
Abstract: Different subfields of physics sometimes share a common thread which is often recognized only in hindsight. I will briefly highlight such an example from the past pointing to ties between lattice QCD and condensed matter physics. I will then share recent developments which suggest that similar ties may exist between a class of non-equilibrium quantum systems known as Floquet insulators and discrete time lattice fermion theories. Floquet insulators are periodically driven quantum systems that can host novel topological phases as a function of the drive parameters. I will show that the spectrum of a certain 1+1 dimensional Floquet system can be replicated exactly using a discrete time static relativistic fermion.
