Aims and Scope

The origin of New Physics: Sae Mulli (NPSM, ISO abbreviation: New Phys.: Sae Mulli.): Sae Mulli (새물리 in Korean characters means ‘new physics’) is the oldest Korean pure scientific journal. It was first published in 1961 just after the Korean War by the Korean Physical Society (KPS). The primary mission of Sae Mulli was to start building up Korean physics research community from almost nothing and in fact Sae Mulli had made tremendous contributions to the Korean science community. Through a peer-review system, Sae Mulli had continued elevating the level of scientific researches, consequently becoming a cornerstone of the economic miracle of Korea...

The Physical Stock Market Modelling and the Daily Price Predicting Indicator

We construct the physical stock market and an indicator for the closing price from the economic function of the stock price flow. The thermodynamical potential of the Bose-Einstein partition function of nonlocal free particles near zero temperature shows that a society having motive serves as the entropy of the potential and states with negative internal energy and participators serve as the number of particles. By connecting the economic function and the internal energy, we find a thermal-state space similar to the Hilbert space of information on the stock price flow. The Hilbert space has a quantum phase operator and a finite number of quantum phase states. Thus, we define it as the physical stock market. The Berry phase of the states is introduced, and the correlation function between the Berry phase and the returns of the stock price is calculated. Thus, the correlation with the current return shows a stable value of about 85% after 5 minutes. The correlation with the closing return shows about 60% and 70% agreement after 50 and 100 minutes from the opening. Thus, we see the Berry phase as a good predictor of the closing price.

Spatial Light Modulator Used as Diffraction Apertures for Advanced Optics Study

Light diffraction requires submillimeter-size apertures. The usual method to make diffraction apertures of various shapes is a photography technique for reducing the size of the aperture pattern to a submillimeter level. Because this method requires much effort and time, we here show that a spatial light modulator (SLM) can serve as a ready-to-use diffraction aperture. Because the pixels of the liquid crystal panel of a SLM can be controlled individually by a simple software to either pass or block the light, one can realize a diffraction aperture of any shape. We tested circular square and hexagonal apertures using a SLM and confirmed that the diffraction patterns agreed with the simulated patterns. The diffraction pattern produced by using a double helix aperture, which is a more complicated shape, looked similar to the X-ray diffraction pattern of DNA. Diffraction is an important tool for structural analysis, but determining the real structure from a diffraction pattern is not easy. For that reason, we suggest that SLM apertures may be a handy and practical tool for teaching and learning about diffraction theory.
