The Avogadro number, which had been considered as a synonym of infinity, is now becoming a big, but finite and reacheable number using high-performance computers realizing now. For example, the K computer in Kobe recorded faster than 10 PFLOPS (10^<16> arithmetic operations per second) , therefore 1 mol operations are achieved if one use it for two years, one of big challenges of such "Avogadro-scale" computer will naturally be in a statistical physics: a challenge to connect nanoscopic molecules and macroscopic phenomena. Using simple molecular models, equilibrium and linear nonequilibrium phenomena have been reproduced by molecular dynamics simulations. Studies on nonlinear nonequilibrium phenomena have started using systems of sizes of around 1,000^3 now, aiming at reproduction of complex autonomous systems like life using 10,000^3 systems.

We briefly review the birth of the Progress of Theoretical Physics (PTP) and its relationship with Journal of the Physical Society of Japan (JPSJ). We also trace the development of PTP and the route to rebirth as Progress of Theoretical and Experimental Physics (PTEP). Furthermore, we introduce some milestone papers of PTP in both fields of particle physics and condensed matter physics.

In frustrated magnets, novel spin structures are often stabilized due to the competing interactions. We theoretically investigate the ordering of the frustrated triangular-lattice Heisenberg antiferromagnet with strong further-neighbor interactions. Several types of multiple-q state, including the skyrmion-lattice state, is observed in addition to the standard single-q state.

X-ray irradiation to molecular conductors introduces molecular defects inside the crystal. Recently, we found that disorder induced by X-ray irradiation to the dimer-Mott type molecular conductor κ-(BEDT-TTF)_2Cu[N(CN)_2]Y(Y=Br,Cl) causes an electron localization state, that is, Anderson localization state due to randomness, from the superconducting state (Y=Br) and the Mott insulating state (Y=Cl). In this article, we show the Mott-Anderson transition of correlated electrons with randomness in the κ-type BEDT-TTF based molecular conductors which possess the typical bandwidth controlled Mott transition.
