• 要約等: We study some properties of generalized global symmetry for the charge-q Schwinger model in the Hamiltonian formalism, which is the (1 + 1)-dimensional quantum electrodynamics with a charge-q Dirac fermion. This model has the ℤq 1-form symmetry, which is a remnant of the electric U(1) 1-form symmetry in the pure Maxwell theory. It is known that if we put the theory on closed space, then the Hilbert space is decomposed into q distinct sectors, called universes and some states with higher energy density do not decay to the ground state due to the selection rule of the 1-form symmetry. Even with open boundaries, we can observe the stability of such states by seeing a negative string tension behavior, meaning that opposite charges repel with each other. In order to see negative string tensions, the vacuum angle θ has to be large enough and the standard path-integral Monte Carlo method suffers from the sign problem. We develop a method based on the adiabatic state preparation to see this feature with digital quantum simulation and confirm it using a classical simulator of quantum devices. Especially, we measure local energy density and see how it jumps between inside and outside of insertion of the probe charges. We explicitly see that the energy density inside is lower than the outside one. This is a clear signature of the negative string tension.; 電荷が反対の粒子間に斥力が働く状況を実現 --量子アルゴリズムの新たな応用--. 京都大学プレスリリース. 2022-02-28.; Likes repel and opposites can too?: KyotoU uses quantum algorithm to study unusual electric charge behavior. 京都大学プレスリリース. 2022-05-16.
