Spinor-helicity calculation of the amplitude at the tree level
Jan Ferdyan, Błażej Ruba
We compute amplitudes for the process (two virtual gluons into a quark, antiquark and a boson) at the tree level using the spinor-helicity formalism…
SU(2)-equivariant quantum channels: semiclassical analysis
Tommaso Aschieri, Błażej Ruba, Jan Philip Solovej
We study completely positive and trace-preserving equivariant maps between operators on irreducible representations of . We find asymptotic approximations of channe…
Point potentials on Euclidean space, hyperbolic space and sphere in any dimension
Jan Dereziński, Christian Gaß, Błażej Ruba
In dimensions d= 1, 2, 3 the Laplacian can be perturbed by a point potential. In higher dimensions the Laplacian with a point potential cannot be defined as a self-adjoint operator…
Ground state energy of dense gases of strongly interacting fermions
Søren Fournais, Błażej Ruba, Jan Philip Solovej
We study the ground state energy of a gas of fermions confined to a unit box in dimensions. The particles interact through a 2-body potential with strength scaled in an …
