DOI: 10.1007/s10714-022-02912-9
Abstract: The article aims to analyze a construction of charges (conserved quantities) for the gravity field in the (3+1) decomposition. The construction is based on (3+1) splitting of conformal Yano–Killing (CYK) two-form. The splitting leads to… read more here.

DOI: 10.1088/1742-5468/ab5d0c
Abstract: We study a gas of point particles with hard-core repulsion in one dimension where the particles move freely in-between elastic collisions. We prepare the system with a uniform density on the infinite line. The velocities… read more here.

Abstract: We discover that quantum dynamical tunneling, occurring between phase space regions in a classically forbidden way, can break conserved quantities. We rigorously prove that a conserved quantity in a class of typical pseudointegrable systems can… read more here.

DOI: 10.1103/physreve.97.012129
Abstract: In quantum thermodynamics, effects of finiteness of the baths have been less considered. In particular, there is no general theory which focuses on finiteness of the baths of multiple conserved quantities. Then, we investigate how… read more here.
