Anomalously Soft Droplets and Aging in Short-ranged Spin Glasses
Hajime Yoshino, Koji Hukushima, Hajime Takayama
We extend the standard droplet scaling theory for isothermal aging in spin glasses assuming that the effective stiffness constant of droplets as large as extended defects is vanish…

Fragility of the glassy state of a directed polymer in random media: a replica approach
Marta Sales, Hajime Yoshino
We study the stability of the glassy equilibrium state of a directed polymer in random media against weak perturbations including the intriguing problem of temperature-chaos. The s…

Numerical Study on Aging Dynamics in Ising Spin-Glass Models: Temperature-Change Protocols
Tatsuo Komori, Hajime Yoshino, Hajime Takayama
By means of Monte Carlo simulations on the three-dimensional Ising spin-glass model, we have studied aging phenomena with various temperature()-change protocols. Particularly, a…
