WebJulian Seymour Schwinger (/ ˈ ʃ w ɪ ŋ ər /; February 12, 1918 – July 16, 1994) was a Nobel Prize-winning American theoretical physicist.He is best known for his work on quantum electrodynamics (QED), in particular for developing a relativistically invariant perturbation theory, and for renormalizing QED to one loop order.Schwinger was a physics professor at … WebMay 4, 2024 · Tracking the dynamics of physical systems in real time is a prime application of quantum computers. Using a trapped-ion system with up to six qubits, we simulate the real-time dynamics of a lattice gauge theory in 1 + 1 dimensions, i.e., the lattice Schwinger model, and demonstrate nonperturbative effects such as pair creation for times much …

Mesoscopic Klein-Schwinger effect in graphene Nature Physics
The Schwinger effect is a predicted physical phenomenon whereby matter is created by a strong electric field. It is also referred to as the Sauter–Schwinger effect, Schwinger mechanism, or Schwinger pair production. It is a prediction of quantum electrodynamics (QED) in which electron–positron pairs are spontaneously created in the presence of an electric field, thereby causing the … WebMar 26, 2024 · avors of Schwinger bosons on each site, created by the canonical operator sy i , with =";#, and j0iis the vacuum with no Schwinger bosons. The total number of Schwinger bosons, n s, is the same for all the states; therefore sy i s i = n s (3) with n s = 2S(we will henceforth assume an implied summation over repeated upper and lower indices). http://qpt.physics.harvard.edu/phys268b/Lec11_Schwinger_boson_theory_of_Z2_spin_liquids.pdf elf boots for sale
