Topological Unwinding in an Exciton-Polariton Condensate Array
Guitao Lyu, Yuki Minami, Na Young Kim +2
The phase distribution in a Bose-Einstein condensate can realize various topological states classified by distinct winding numbers. While states with different winding numbers are…
Spontaneous symmetry breaking in two dimensions under nonequilibrium laminar flows
Yuki Minami, Hiroyoshi Nakano
We study the long-range order in two dimensions where an order parameter is advected by laminar flows such as rotational, shear, and elongational flows. Under these flows, we analy…
Effects of pairing gap and band gap on superfluid density in the inner crust of neutron stars
Yuki Minami, Gentaro Watanabe
Calculations of the superfluid density in the inner crust of neutron stars by different approaches are in strong disagreement, which causes a debate on the accountability of pulsar…
Relation between fluctuations and efficiency at maximum power for small heat engines
Guo-Hua Xu, Chao Jiang, Yuki Minami +1
We study the ratio between the variances of work output and heat input, , for a class of four-stroke heat engines which covers various typical cycles. Recent studies on th…
Molecular dynamics study of shear-induced long-range correlations in simple fluids
Hiroyoshi Nakano, Yuki Minami
We investigate long-range correlations (LRCs) induced by shear flow using the molecular dynamics (MD) simulation. We observe the LRCs by comparing the MD results with the linearize…
Finite-Time Thermodynamics of Fluctuations in Microscopic Heat Engines
Gentaro Watanabe, Yuki Minami
Fluctuations of thermodynamic quantities become non-negligible and play an important role when the system size is small. We develop finite-time thermodynamics of fluctuations in mi…

Hiroyoshi Nakano, Yuki Minami, Shin-ichi Sasa
We theoretically and numerically investigate a two-dimensional O(2) model where an order parameter is convected by shear flow. We show that a long-range phase order emerges in two…

We study the thermodynamic entropy as a Noether invariant in a stochastic process. Following the Onsager theory, we consider the Langevin equation for a thermodynamic variable in a…
Spontaneous symmetry breaking and Nambu-Goldstone modes in open classical and quantum systems
Yoshimasa Hidaka, Yuki Minami
We discuss spontaneous symmetry breaking of open classical and quantum systems. When a continuous symmetry is spontaneously broken in an open system, a gapless excitation mode appe…
The most effective model for describing the universal behavior of unstable surface growth
Yuki Minami, Shin-ichi Sasa
We study a noisy Kuramoto-Sivashinsky (KS) equation which describes unstable surface growth and chemical turbulence. It has been conjectured that the universal long-wavelength beha…
