Theory of Anderson localization on the hyperbolic plane
Alexander Altland, Tobias Micklitz, Devasheesh Sharma +2
The two-dimensional hyperbolic plane, , is an unusual system in that dimensionality changes with scale: locally two-dimensional and planar at short distances, but eff…
Continuum field theory of matchgate tensor network ensembles
Maksimilian Usoltcev, Carolin Wille, Jens Eisert +1
Tensor networks provide discrete representations of quantum many-body systems, yet their precise connection to continuum field theories remains relatively poorly understood. Invoki…
A minimal tensor network beyond free fermions
Carolin Wille, Maksimilian Usoltcev, Jens Eisert +1
This work proposes a minimal model extending the duality between classical statistical spin systems and fermionic systems beyond the case of free fermions. A Jordan-Wigner transfor…
Classical simulation of parity-preserving quantum circuits
Carolin Wille, Sergii Strelchuk
We present a classical simulation method for fermionic quantum systems which, without loss of generality, can be represented by parity-preserving circuits made of two-qubit gates i…
