Imaginary pseudo entropy encodes temporal orientation
Tatsuhiro Misumi
Pseudo entropy between quantum states at different times is generally complex, yet its imaginary part has lacked a bounded operational meaning. We show that a calibrated replica in…
Lattice fermion formulation via Physics-Informed Neural Networks: Ginsparg-Wilson relation and Overlap fermions
Tatsuhiro Misumi
We propose a novel, machine-learning-based framework for constructing lattice fermions using Physics-Informed Neural Networks (PINNs). Our approach treats the formulation of the Di…
Real-time pseudo entropy and modular-Hamiltonian correlations
Tatsuhiro Misumi
Pseudo entropy is a complex-valued generalization of entanglement entropy defined from a reduced transition matrix. We study the pseudo entropy associated with a real-time transiti…
Exact WKB analysis of inverted triple-well: resonance, PT-symmetry breaking, and resurgence
Syo Kamata, Tatsuhiro Misumi, Cihan Pazarbaşı +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…
Adiabatic continuity in a partially reduced twisted Eguchi-Kawai model with one adjoint Dirac fermion
Yudai Hamada, Tatsuhiro Misumi
We numerically investigate whether the center-symmetric confined phase of large- gauge theory with one adjoint Dirac fermion persists under spatial compactification on $…
Taste-splitting mass and edge modes in D staggered fermions
Tatsuhiro Misumi, Tetsuya Onogi, Tatsuya Yamaoka
We investigate the symmetry structure of the D staggered fermion Hamiltonian and its implications for anomalies. Since the spin and flavor degrees of freedom of Dirac fermion…
