[Theory-seminars] Seminars next week

[Carlota Andres Casas]

Dear all,

Here is a reminder for the seminars next week, but before an important announcement:

>From next week on, we will not provide disposable cups for the coffee during the theory and cake seminars, so please bring your own mugs to the seminars. We are trying to be more eco-friendly!

Theory seminar
Monday, Jan 27, 1:00PM, Room L102

Indrakshi Raychowdhury (Maryland Univ), "Towards Quantum Simulating Non-Abelian Lattice Gauge Theory''

Abstract:
In this talk, we discuss a complete and efficient formulation for SU(2) lattice gauge theory with fundamental matter and establish this to be a practical framework for digital as well as analog quantum simulation. Key features of this framework include a gauge-invariant and readily-digitized basis, together with a representation of the Hamiltonian in terms of simple ladder operators. We show that within this formulation, the physical sector of the non-Abelian lattice gauge theories are made equivalent to Abelian theories. Utilizing this feature, we can directly generalize the simulation techniques, already present for Schwinger model towards constructing proposals for
simulating  non-Abelian lattice gauge theories.


Theory seminar
Wednesday, Jan 29, 1:00PM, Room F326-327
Sergio Scopetta (Perugia U.), "Realistic studies of the 3D-parton structure of He nuclei''

Abstract:
Novel coincidence measurements at high luminosity facilities, such as Jefferson Laboratory at 12 GeV  and the future Electron Ion Collider, will lay  the ground for a new era in the knowledge of the elusive nuclear parton structure of  nuclei. Semi-inclusive and hard exclusive electron scattering off light nuclei, for which realistic calculations are possible, will be crucial in exposing possible novel quark and gluon effects in nuclei. The high precision of the expected data at high energy requires the  use of realistic theoretical tools for the planning of future measurements and for their interpretation. The status of the calculations of 3He spin dependent spectral functions, in plane wave impulse approximation and including final state interaction effects, will be described, summarizing recent theoretical results for SIDIS and DVCS off 3He. The extension to DVCS for 4He, and the status of relativistic light front calculations for 3He, will be eventually briefly addressed.
