Lindblad evolution without the sign problem
Tomoya Hayata
Quantum Monte Carlo is one of the most powerful numerical tools for studying nonpeturbative properties of quantum many-body systems. However, its application to real-time problems…
Non-Hermitian Hubbard model without the sign problem
Tomoya Hayata, Arata Yamamoto
We study the Hubbard model with non-Hermitian asymmetric hopping terms. The conjugate hopping terms are introduced for two spin components so that the negative sign is canceled out…
Diagnosis of information scrambling from Hamiltonian evolution under decoherence
Tomoya Hayata, Yoshimasa Hidaka, Yuta Kikuchi
We apply a quantum teleportation protocol based on the Hayden-Preskill thought experiment to quantify how scrambling a given quantum evolution is. It has an advantage over the dire…
Second order chiral kinetic theory under gravity and antiparallel charge-energy flow
Tomoya Hayata, Yoshimasa Hidaka, Kazuya Mameda
We derive the chiral kinetic theory under the presence of a gravitational Riemann curvature. It is well-known that in the chiral kinetic theory there inevitably appears a redundant…
Thermalization of Yang-Mills theory in a dimensional small lattice system
Tomoya Hayata, Yoshimasa Hidaka
We study the real-time evolution of SU() Yang-Mills theory in a dimensional small lattice system after interaction quench. We numerically solve the Schr{ö}dinger equatio…
Chirality-driven edge flow and non-Hermitian topology in active nematic cells
Lisa Yamauchi, Tomoya Hayata, Masahito Uwamichi +2
Many of the biological phenomena involve collective dynamics driven by self-propelled motion and nonequilibrium force (i.e., activity) that result in features unexpected from equil…
