Nonequilibrium Steady States in the Weakly-Coupled XXZ Model
Shimpei Senda, Tatsuro Sunami, Yuto Matsumoto +1
We study nonequilibrium steady states (NESSs) in the weakly-coupled XXZ model in contact with two heat baths at different temperatures. We show that the density matrix can be repre…
Periodic three-body orbits in the Coulomb potential
Marija Šindik, Ayumu Sugita, Milovan Šuvakov +1
We numerically discovered around 100 distinct nonrelativistic collisionless periodic three-body orbits in the Coulomb potential in vacuo, with vanishing angular momentum, for equal…
Linear stability of periodic three-body orbits with zero angular momentum and topological dependence of Kepler's third law: a numerical test
V. Dmitrašinović, Ana Hudomal, Mitsuru Shibayama +1
We test numerically the recently proposed linear relationship between the scale-invariant period , and the topology of an orbit, on several hundred plan…
Origin of Temperature Gradient in Nonequilibrium Steady States in Weakly Coupled Quantum Spin Systems
Toyohiko Ishida, Ayumu Sugita
We study nonequilibrium steady states (NESSs) in quantum spin-1/2 chains in contact with two heat baths at different temperatures. We consider the weak-coupling limit both for spin…
The Fall of Black Hole Firewall: Natural Nonmaximal Entanglement for Page Curve
Masahiro Hotta, Ayumu Sugita
The black hole firewall conjecture is based on Page curve hypothesis, which claims that entanglement between black hole and Hawking radiation is almost maximum. The hypothesis is i…
A perturbative method for nonequilibrium steady state of open quantum systems
Tatsuro Yuge, Ayumu Sugita
We develop a method of calculating the nonequilibrium steady state (NESS) of an open quantum system that is weakly coupled to reservoirs in different equilibrium states. We describ…
