Entanglement transitions in a boundary-driven open quantum many-body system
Darvin Wanisch, Nora ReiniÄ, Daniel Jaschke +2
We introduce a numerical framework for integrating Markovian dynamics on tree tensor operator (TTO) ansatz states. This framework enables the simulation of both transient and stead…

A new rung on the ladder: exploring topological frustration towards two dimensions
Alberto Giuseppe Catalano, Nora ReiniÄ, Gianpaolo Torre +5
Topological frustration arises when boundary conditions impose geometric frustration in a quantum system, creating delocalized defects in the ground states and profoundly altering…

The Augmented Tree Tensor Network Cookbook
Nora ReiniÄ, Luka PaveÅ¡iÄ, Daniel Jaschke +1
An augmented tree tensor network (aTTN) is a tensor network ansatz constructed by applying a layer of unitary disentanglers to a tree tensor network. The disentanglers absorb a par…
