Extracting central charge from ground-state overlaps of spatially deformed Hamiltonians
Chen Bai, Xinyu Sun, Liang-Hong Mo +1
We show that the conformal anomaly of a -dimensional conformal field theory can be extracted directly from a ground-state wave-function overlap associated with a spatial con…
Nonreciprocity Induced Fractional Nonlinear Thouless Pumping
Yanqi Zheng, Kun Pu, Ligging Ren +2
Recent interest has surged in eigenvalue's nonlinearity-based topological transport governed by the equation of auxiliary eigenvalues [T. Isobe et al., Phys. Rev. L…
Bootstrapping Symmetries in Quantum Many-Body Systems from the Cross Spectral Form Factor
Chen Bai, Zihan Zhou, Bastien Lapierre +1
Symmetries play a central role in quantum many-body physics, yet uncovering them systematically remains challenging. We introduce a bootstrap framework designed to reconstruct the…
Fractional Thouless pumping of solitons: a unique manifestation of bulk-edge correspondence of nonlinear eigenvalue problems
Chenxi Bai, Zhaoxin Liang
Recent foundational studies have established the bulk-edge correspondence for nonlinear eigenvalue problems using auxiliary eigenvalues , spanning both linear…
Anomalous bulk-edge correspondence of nonlinear Rice-Mele model
Chenxi Bai, Zhaoxin Liang
Bulk-edge correspondence (BEC) constitutes a fundamental concept within the domain of topological physics, elucidating the profound interplay between the topological invariants tha…
