DOI: 10.1007/jhep02(2022)041
Abstract: Abstract We study monodromy defects in O(N) symmetric scalar field theories in d dimensions. After a Weyl transformation, a monodromy defect may be described by placing the theory on S1 × Hd−1, where Hd−1 is… read more here.

DOI: 10.1007/jhep03(2025)115
Abstract: We utilize three complementary approaches to pinpoint the exact form of scattering amplitudes in Schwarzschild spacetime. First, we solve the Regge-Wheeler equation perturbatively in the small-frequency regime. We use the obtained solutions to determine the… read more here.

DOI: 10.1063/5.0079354
Abstract: An integrable Hamiltonian system presents monodromy if the action-angle variables cannot be defined globally. As a prototype of classical monodromy with azimuthal symmetry, we consider a linear molecule interacting with external fields and explore the… read more here.

DOI: 10.1093/imrn/rnae245
Abstract: We compute the monodromy of the mirabolic $\mathcal{D}$-module for all values of the parameters $(\vartheta ,c)$ in rank 1 and outside an explicit codimension 2 set of values in ranks 2 and higher. This shows… read more here.
