Algebraic Tomography of Non-Hermitian Floquet Systems from Observable Traces

Syo Kamata

We formulate a framework of Floquet algebraic tomography for finite-dimensional non-Hermitian monodromy matrices from observable trace sequences $I^¶_{n}^{(O)} = Tr (O M^{n})$ . Since…

Exact WKB analysis of inverted triple-well: resonance, PT-symmetry breaking, and resurgence

Syo Kamata, Tatsuhiro Misumi, Cihan PazarbaÅÄ± +1

We study non-Hermitian quantum mechanics of an inverted triple-well potential within the exact WKB framework. For a single classical potential, different Siegert boundary condition…

Exact Sum Rules and Zeta Generating Formulas from the ODE/IM correspondence

Syo Kamata

We develop a spectral-zeta framework for quantum mechanics with the $P T$ -symmetric potential $V_{P T} (x) = x^{2 K} (i x)^{ε}$ $(K, ε \in N)$ and…

Topological Uncertainty for Anomaly Detection in the Neural-network EoS Inference with Neutron Star Data

Kenji Fukushima, Syo Kamata

We study the performance of the Topological Uncertainty (TU) constructed with a trained feedforward neural network (FNN) for Anomaly Detection. Generally, meaningful information ca…
