String dynamics of a (2+1)D U(1) quantum link model on a digital quantum computer
Anthony Gandon, Alessandro Mariani, Debasish Banerjee +5
The (2+1)D U(1) pure gauge theory always exists in the confining phase, with strings of non-zero string tension giving a characteristic linear potential between static charges. Thi…
Two-dimensional Lattice Gauge Theories with Superconducting Quantum Circuits
D. Marcos, P. Widmer, E. Rico +4
A quantum simulator of U(1) lattice gauge theories can be implemented with superconducting circuits. This allows the investigation of confined and deconfined phases in quantum link…
Ultracold Quantum Gases and Lattice Systems: Quantum Simulation of Lattice Gauge Theories
U. -J. Wiese
Abelian and non-Abelian gauge theories are of central importance in many areas of physics. In condensed matter physics, Abelian U(1) lattice gauge theories arise in the description…
Self-adjoint Extensions for Confined Electrons:from a Particle in a Spherical Cavity to the Hydrogen Atom in a Sphere and on a Cone
M. H. Al-Hashimi, U. -J. Wiese
In a recent study of the self-adjoint extensions of the Hamiltonian of a particle confined to a finite region of space, in which we generalized the Heisenberg uncertainty relation…
From a Particle in a Box to the Uncertainty Relation in a Quantum Dot and to Reflecting Walls for Relativistic Fermions
M. H. Al-Hashimi, U. -J. Wiese
We consider a 1-parameter family of self-adjoint extensions of the Hamiltonian for a particle confined to a finite interval with perfectly reflecting boundary conditions. In some c…
Discrete Accidental Symmetry for a Particle in a Constant Magnetic Field on a Torus
M. H. Al-Hashimi, U. -J. Wiese
A classical particle in a constant magnetic field undergoes cyclotron motion on a circular orbit. At the quantum level, the fact that all classical orbits are closed gives rise to…
Runge-Lenz Vector, Accidental SU(2) Symmetry, and Unusual Multiplets for Motion on a Cone
M. H. Al-Hashimi, U. -J. Wiese
We consider a particle moving on a cone and bound to its tip by or harmonic oscillator potentials. When the deficit angle of the cone divided by is a rational number, a…
