Minimal-doubling and single-Weyl Hamiltonians
Tatsuhiro Misumi
We develop a systematic Hamiltonian formulation of minimally doubled lattice fermions in (3+1) dimensions, derive their nodal structures (structures of zeros), and classify their s…
Exact WKB in all sectors II: Potentials with non-degenerate saddles
Tatsuhiro Misumi, Cihan Pazarbaşı
We discuss the exact quantization of general one-dimensional potentials in view of the exact-WKB formalism. Building on our previous work, we perform analytic continuations across…
Fractional instantons in 2d model and 4d Yang-Mills theory with 't Hooft twists
Yui Hayashi, Tatsuhiro Misumi, Muneto Nitta +2
We derive the explicit formula for fractional BPS lumps (or fractional instantons) in the nonlinear sigma model on a two-dimensional torus under various shift-c…
stability and continuity in twisted Eguchi-Kawai model with two-flavor adjoint fermions
Yudai Hamada, Tatsuhiro Misumi
We investigate the twisted Eguchi-Kawai (TEK) reduced model of four-dimensional gauge theory in the presence of two-flavor adjoint fermions (adjoint TEK model). Using Monte…
Exact-WKB Analysis of Two-level Floquet Systems
Toshiaki Fujimori, Syo Kamata, Tatsuhiro Misumi +2
We explore the application of the exact Wentzel-Kramers-Brillouin (WKB) analysis to two-level Floquet systems and establish a systematic procedure to calculate the quasi-energy and…
