The pith

Floating Majorana edge bands produce quantized thermal conductance in time-reversal-breaking superconductors.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper identifies floating Majorana edge bands as isolated counterpropagating Majorana modes that detach from the bulk continuum in two-dimensional superconductors that break time-reversal symmetry. These bands arise from anisotropic Wilson masses in a two-band Bogoliubov-de Gennes model and appear microscopically when a quantum anomalous Hall insulator is placed in contact with a d-wave superconductor. Their transport signature is a quantized total thermal conductance in two-terminal devices together with a robust half-quantized plateau in four-terminal geometries. The response remains stable against moderate long-range disorder, finite temperature, and nonzero chemical potential, providing a route to helical-like Majorana transport without time-reversal symmetry.

Core claim

Floating Majorana edge bands form isolated, momentum-separated counterpropagating Majorana modes detached from the bulk continuum. In a quantum anomalous Hall insulator proximitized by a d-wave superconductor, these bands produce a quantized total thermal conductance in two-terminal devices and a robust half-quantized plateau in four-terminal geometries that distinguishes them from chiral N=±2 quantum anomalous Hall phases.

What carries the argument

Floating Majorana edge bands (FMEBs): momentum-separated counterpropagating Majorana modes that remain detached from the bulk continuum and carry the thermal transport.

If this is right

  • Quantized total thermal conductance appears in two-terminal devices.
  • A robust half-quantized plateau forms in four-terminal geometries.
  • The signatures cleanly separate floating Majorana edge bands from chiral N=±2 quantum anomalous Hall phases.
  • Thermal response stays stable under finite temperature, moderate long-range disorder, and finite chemical potential.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Similar bands may appear in other pairings or material stacks that produce anisotropic masses.
  • The half-quantized plateau offers an experimental handle for detecting helical-like Majorana transport in non-time-reversal-symmetric platforms.
  • Stability under disorder suggests these modes could be used in devices where conventional chiral or helical edges would be disrupted.

Load-bearing premise

The isolated counterpropagating modes appear only when anisotropic Wilson masses are realized in the two-band Bogoliubov-de Gennes model of a quantum anomalous Hall insulator proximitized by a d-wave superconductor.

What would settle it

Absence of the half-quantized thermal conductance plateau in four-terminal measurements under moderate disorder would rule out the claimed isolation and robustness of the floating Majorana edge bands.

We propose and characterize a new class of Majorana boundary states, i.e., floating Majorana edge bands (FMEBs), which emerge in two-dimensional (2D) superconductors that break time-reversal symmetry yet host helical-like transport. In contrast to conventional chiral or helical edge modes, FMEBs form isolated, momentum-separated counterpropagating Majorana modes detached from the bulk continuum. We identify a minimal mechanism for their emergence via anisotropic Wilson masses in a two-band Bogoliubov-de Gennes (BdG) model, and demonstrate their microscopic realization in a quantum anomalous Hall (QAH) insulator proximitized by a $d$-wave superconductor. Using nonequilibrium Green's function (NEGF) simulations, we uncover clear transport fingerprints: a quantized total thermal conductance in two-terminal devices, and a robust half-quantized plateau in four-terminal geometries that cleanly distinguishes FMEBs from chiral $\mathcal{N}= \pm 2$ QAH phases. This thermal response remains remarkably stable under finite temperature, moderate long-range disorder, and finite chemical potential. Our findings establish FMEBs as an experimentally accessible route toward helical-like Majorana transport in systems without time-reversal symmetry, with direct implications for topological quantum computation.

Referee Report

2 major / 1 minor

Summary. The manuscript proposes floating Majorana edge bands (FMEBs) as a new class of isolated, momentum-separated counterpropagating Majorana modes in time-reversal symmetry breaking 2D superconductors. These emerge via anisotropic Wilson masses in a two-band BdG model microscopically realized by proximitizing a QAH insulator with d-wave superconductivity. NEGF transport simulations are used to demonstrate a quantized total thermal conductance in two-terminal geometries and a robust half-quantized plateau in four-terminal setups that distinguishes FMEBs from chiral N=±2 QAH phases, with the signatures remaining stable under finite temperature, moderate disorder, and finite chemical potential.

Significance. If the isolation of the FMEBs from the bulk continuum holds and the transport quantization is not an artifact, the work identifies a new mechanism for helical-like Majorana transport without TRS, offering clear experimental fingerprints via thermal conductance that could be relevant for topological quantum computation. The use of NEGF to extract falsifiable transport predictions is a positive aspect of the numerical approach.

major comments (2)
  1. [BdG model and microscopic realization] The central claim that FMEBs remain detached from the bulk continuum (producing the reported quantized conductances) rests on anisotropic Wilson masses in the two-band BdG model. However, d-wave pairing is nodal and momentum-dependent; the manuscript must demonstrate explicitly that the anisotropy opens a full gap at all Brillouin-zone momenta where the floating bands exist and prevents hybridization. Without the bulk dispersion or DOS shown for the microscopic QAH+d-wave realization, the NEGF signatures alone do not establish isolation (see the sections on the minimal mechanism and microscopic realization).
  2. [NEGF transport simulations] The two-terminal quantized thermal conductance and four-terminal half-quantized plateau are load-bearing for distinguishing FMEBs from chiral phases. The NEGF results should include convergence checks with respect to system size, lead coupling, and disorder averaging, as finite-size effects or partial spectral overlap could mimic quantization without true isolation of counterpropagating modes.
minor comments (1)
  1. [Abstract and introduction] Clarify the precise definition of 'floating' in the introduction, as the term is used to emphasize detachment from the bulk but could be confused with other edge-state terminology.

  1. Referee: [BdG model and microscopic realization] The central claim that FMEBs remain detached from the bulk continuum (producing the reported quantized conductances) rests on anisotropic Wilson masses in the two-band BdG model. However, d-wave pairing is nodal and momentum-dependent; the manuscript must demonstrate explicitly that the anisotropy opens a full gap at all Brillouin-zone momenta where the floating bands exist and prevents hybridization. Without the bulk dispersion or DOS shown for the microscopic QAH+d-wave realization, the NEGF signatures alone do not establish isolation (see the sections on the minimal mechanism and microscopic realization).

    Authors: We agree that explicit confirmation of the bulk gap is required to rigorously establish isolation of the FMEBs. In the revised manuscript we add the bulk dispersion and density-of-states plots for both the minimal two-band BdG model (with anisotropic Wilson masses) and the microscopic QAH+d-wave realization. These figures show that the anisotropy produces a full gap at all Brillouin-zone momenta relevant to the floating bands, with no spectral overlap or hybridization channels to the bulk continuum. The added data directly support the NEGF transport results and confirm that the observed quantization originates from truly detached counterpropagating Majorana modes. revision: yes

  2. Referee: [NEGF transport simulations] The two-terminal quantized thermal conductance and four-terminal half-quantized plateau are load-bearing for distinguishing FMEBs from chiral phases. The NEGF results should include convergence checks with respect to system size, lead coupling, and disorder averaging, as finite-size effects or partial spectral overlap could mimic quantization without true isolation of counterpropagating modes.

    Authors: We appreciate the referee’s emphasis on numerical convergence. The revised manuscript now includes explicit checks: thermal conductance versus system size (up to substantially larger lattices), versus lead-coupling strength, and averaged over an increased number of disorder realizations. These additional results demonstrate that the two-terminal quantization and four-terminal half-quantized plateau converge to the reported values and remain stable, excluding finite-size artifacts or incomplete averaging as explanations. The distinction from chiral N=±2 phases is thereby reinforced. revision: yes

Circularity Check

0 steps flagged

No significant circularity; derivation is self-contained numerical simulation of explicitly defined BdG model

full rationale

The paper defines a two-band BdG model incorporating anisotropic Wilson masses as the minimal mechanism for FMEBs, then computes transport signatures (quantized thermal conductance, half-quantized plateaus) directly via NEGF simulations on that model. No load-bearing self-citations, no parameters fitted to data and renamed as predictions, and no ansatz or uniqueness theorem imported from prior author work. The results follow from solving the stated Hamiltonian without any step reducing by construction to its own inputs; the central claims rest on explicit numerical output rather than circular redefinition.
