We analyze the charge and thermal transport at a junction of interacting quantum wires
close to equilibrium. Within the framework of Tomonaga-Luttinger liquids, we compute the …

We consider the optimal control of switching on a coupling term between two quantum many-
body systems. Specifically, we (i) quantify the energetic cost of establishing a weak junction …

We use junctions of critical spin-1 chains as the basic elements to construct a honeycomb
network that harbors a gapless chiral spin liquid phase. The low-energy modes are …

In this paper we propose a special type of a tree tensor network that has the geometry of a
comb—a one-dimensional (1D) backbone with finite 1D teeth projecting out from it. This …

Demonstrating the non-Abelian Ising anyon statistics of Majorana zero modes in a physical
platform still represents a major open challenge in physics. We here show that the linear low …

We use a network of chiral junctions to construct a family of topological chiral spin liquids in
two spatial dimensions. The chiral spin liquid phase harbors SU (2) $ _k $ anyons, which …

We show that a honeycomb lattice of Heisenberg spin-1/2 chains with three-spin junction
interactions allows for controlled analytical studies of chiral spin liquids (CSLs). Tuning …

Junctions of one-dimensional systems are of great interest to the development of synthetic
materials that harbor topological phases. We study a junction of three gapless spin-1 chains …

The problem of bacterial photosynthesis has attracted much recent interest since the
molecular structures of the photosynthetic reaction center (RC) in purple bacteria …

Power-law suppression of local electronic tunneling density of states (TDOS) in the zero-
energy limit is a hallmark of the Luttinger liquid (LL) phase of the interacting one …
