Holonomy Separation and Anyonic Hair in AdS
Kumar Ghosh
Three-dimensional Einstein gravity and Chern-Simons-Higgs matter both admit Chern-Simons descriptions, but their holonomies encode different physics. We prove that charge conjugati…
Self-calibrating thermal interferometry of vortex parity in a two-dimensional chiral superconductor
Kumar Ghosh
A chiral superconductor carries chiral Majorana modes along its boundary, and the integer that counts them fixes everything that follows, yet that integer has never been measured t…
Thermal Hall tomography of chiral superconductivity in rhombohedral graphene
Kumar Ghosh
A chiral superconductor carries chiral Majorana modes along its edges, and a single integer, the Bogoliubov--de Gennes Chern number, counts them. Thirty years of candidate material…
Parity Anomaly of Preformed Pairs Governs the Thermal Hall Effect above
Kumar Ghosh
A large negative thermal Hall signal has been reported across multiple cuprate families in the pseudogap phase where the superconducting order parameter has vanished, with a magnit…
From Dirac Cones to Semions: An Exact Finite-Size Theory of Parity-Anomaly Transport in Chiral Spin Liquids
Kumar Ghosh
Chiral spin liquids realize a topological state whose universal response is a fractional spin Hall conductance . The three quantities that determine this response, the integer…
Exploring Replica Symmetry Breaking and Topological Collapse in Spin Glasses with Quantum Annealing
Kumar Ghosh
Replica symmetry breaking (RSB) underlies the complex organization of disordered systems, yet quantitative validation beyond spins has remained computationally challen…
