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…
Hate speech toward migrants on a citizen reporting platform concentrates in neighborhoods undergoing demographic change
Eduardo Graells-Garrido, Daniela Opitz, Francisco Rowe +1
Understanding when migration generates social integration or exclusion is a central challenge for urban communities. Existing research has mostly relied on surveys, administrative…
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 intege…
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…
