Experimental benchmark of the quantum-classical crossover in a spin ladder
Hironori Yamaguchi, Itsuki Shimamura, Akira Matsuo +4
We report a spin-(1/2, 5/2) three-leg ladder realized in a radical-Mn polymer, exhibiting an antiferromagnetic transition and magnetization curves accurately described by classical…
Integrable -graded super-Liouville Equation and Induced -graded super-Virasoro Algebra
Naruhiko Aizawa, Ichi Fujii, Ren Ito +2
We present a framework for enlarging the construction of -graded classical Toda theory from the class of -graded Lie algebras to the class of $\math…
Random matrix perspective on probabilistic error cancellation
Leonhard Moske, Pedro Ribeiro, Tomaž Prosen +3
Probabilistic error cancellation is an attempt to reverse the effect of dissipative noise channels on quantum computers by applying unphysical channels after the execution of a qua…
Regularised density-potential inversion for periodic systems: application to exact exchange in one dimension
Oliver M. Bohle, Maryam Lotfigolian, Andre Laestadius +1
A detailed convex analysis-based formulation of density-functional theory for periodic systems in arbitrary dimensions is presented. The electron-electron interaction is taken to b…
Pseudo-Nambu-Goldstone Dark Matter in Flux Compactification
Kento Akamatsu, Takuya Hirose, Nobuhito Maru +1
We study a six-dimensional U(1) gauge theory compactified on a magnetized torus, where the zero mode of the extra-dimensional gauge field (a Wilson-line (WL) scalar field) play…
Local-density correlation functional from the force-balance equation
Nicolas Tancogne-Dejean, Markus Penz, Michael Ruggenthaler +1
The force-balance equation of time-dependent density-functional theory presents a promising route towards obtaining approximate functionals, however, so far, no practical correlati…
