# Phase-dependent heat transport in Josephson junctions with p-wave superconductors and superfluids

## TL;DR

This paper studies how phase-dependent heat transport in Josephson junctions with unconventional p-wave superconductors and superfluids can reveal pairing symmetries and topological states, using Bogoliubov-de Gennes formalism.

## Contribution

It introduces a detailed analysis of phase-coherent thermal conductance in junctions between triplet superconductors with various pairing symmetries, highlighting their distinct signatures.

## Key findings

- Thermal conductance varies with phase, revealing pairing symmetry.
- Different pairing states produce unique topologically nontrivial bound states.
- Phase dependence can distinguish between helical, chiral unitary, and nonunitary chiral pairings.

## Abstract

We investigate phase-coherent thermal transport in Josephson junctions made from unconventional superconductors or superfluids. The thermal conductance is evaluated for one- and two-dimensional junctions within the Bogoliubov-de Gennes formalism. We analyze three different scenarios of junctions between two triplet superconductors with (i) helical pairing, (ii) unitary chiral and (iii) nonunitary chiral pairing. We find that the phase-dependent thermal conductance allows us to distinguish the different pairings and provides insight into the formation of topologically nontrivial Andreev bound states in the junction.
