Abstract: A method of producing a substance includes a producing step of producing a new substance by, in a state in which a raw material absorbing giant pulse laser light is disposed inside a base material or in a state in which the base material and the raw material are brought into contact with each other and are clamped together, performing irradiation with the giant pulse laser light such that the raw material absorbs the giant pulse laser light and thereby generating shock waves such that at least the raw material undergoes phase transition.

Abstract: A low-noise wide band amplifier is realized utilizing a superconductor-insulator-superconductor (SIS) junction, quasiparticle frequency mixers connected in tandem or in cascade, a first quasiparticle mixer performs first frequency mixing with use of a first local signal having a frequency not less than twice a frequency of an input signal to the first quasiparticle mixer, a second quasiparticle mixer performs second frequency mixing with use of a second local signal having a frequency not more than twice a frequency of an input signal to the second quasiparticle mixer, and signal amplification is performed through frequency conversion by extracting, from among a plurality of signals generated with the first and the second frequency mixing, a signal in a frequency band not more than a frequency band of the signal before the first frequency mixing and the second frequency mixing, using a transmission line or a filter.

Abstract: The present invention is intended to provide an adaptive optics system and an optical device that allow correction of wavefront phase aberration with higher accuracy than before and have a wider correction range than the conventional ones, regardless of the distance between the observation target and the fluctuation layer, and the size of the observation target. An adaptive optics system includes: a wavefront phase modulator that makes aberration correction to incident light and emits the corrected light; and an imaging-conjugated position adjustment mechanism that adjusts freely within a specimen the position of a surface imaging-conjugated with a fluctuation correction surface formed by the wavefront phase modulator. The imaging-conjugated position adjustment mechanism adjusts the fluctuation correction surface to be imaging-conjugated with a fluctuation layer existing in the specimen.

Abstract: A quantum simulator includes a pseudo speckle pattern generator, a main vacuum chamber, an atomic gas supply unit, a light beam generator, a photodetector, and an atom number detector. The pseudo speckle pattern generator generates a pseudo speckle pattern in the inside of the main vacuum chamber by light allowed to enter the inside of the main vacuum chamber through the second window. The pseudo speckle pattern generator includes a controller, a light source, a beam expander, a spatial light modulator, and a lens. The controller sets a modulation distribution of the spatial light modultor based on a two-dimensional pseudo random number pattern.

Abstract: [Problem] To provide an evaluation method for evaluating spectacle lenses that is capable of objectively evaluating spectacle lenses suitable for a user by measuring brain activity, and a design method for designing spectacle lenses using the evaluation method.[Solution] A subject is allowed to wear to-be-evaluated lenses, and the subject is allowed to visually observe a visual stimulus object used to evoke an activity of a specific part of the visual cortex of the brain through the to-be-evaluated lenses, and an evoked activity of the specific part of the brain's visual cortex when the visual stimulus object is visually observed by the to-be-evaluated lenses is measured by an electroencephalograph or by a magnetoencephalograph, and the spectacle lenses are evaluated based on time (latency) from when a visual stimulus is received till when a change is caused thereby or based on the magnitude (amplitude) of activity.

Abstract: A more practical method for evaluating an inhibitory circuit applicable to a living body, and the use thereof. Herein the action of an inhibitory circuit on an excitatory circuit is evaluated on the basis of attenuation of the brain activity produced by activation of an excitatory circuit by the input of an inhibitory circuit by performing a step for inputting an inhibitory circuit by applying a second trigger in advance of a first trigger to an excitatory circuit activated by a first trigger which is a stimulus or challenge.

Abstract: Upon producing a transparent polycrystalline material, a suspension liquid (or slurry 1) is prepared, the suspension liquid being made by dispersing a raw-material powder in a solution, the raw-material powder including optically anisotropic single-crystalline particles to which a rare-earth element is added. A formed body is obtained from the suspension liquid by means of carrying out slip casting in a space with a magnetic field applied. On this occasion, while doing a temperature control so that the single-crystalline particles demonstrate predetermined magnetic anisotropy, one of static magnetic fields and rotary magnetic fields is selected in compliance with a direction of an axis of easy magnetization in the single-crystalline particles, and is then applied to them. A transparent polycrystalline material is obtained by sintering the formed body, the transparent polycrystalline material having a polycrystalline structure whose crystal orientation is controlled.
