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 …

An impurity in a Tomonaga-Luttinger liquid leads to a crossover between the short-and long-
distance regime which describes many physical phenomena. However, a calculation of the …

We discuss how to extend the impurity entropy to systems with boundary interactions
depending on zero-mode real fermion operators (Majorana modes as well as Klein factors) …

We calculate the conductances of a three-way junction of spinless Luttinger-liquid wires as
functions of bias voltages applied to three independent Fermi-liquid reservoirs. In particular …

We study the four-terminal junction of spinless Luttinger liquid wires, which describes either
a corner junction of two helical edge states of topological insulators or the tunneling from the …

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 …

A recent study has shown that it is possible to have enhancement, in contrast to an expected
suppression, in tunneling density of states (TDOS) in a Luttinger liquid (LL) which is solely …

We develop the renormalization group theory of the conductances of N-lead junctions of
spinless Luttinger-liquid wires as functions of bias voltages applied to N independent Fermi …

The renormalization of conductances in a Y junction of spinless Luttinger-liquid wires
additionally coupled to acoustic longitudinal phonons is investigated in fermionic …
