Hierarchy of QM SUSYs on a Bounded Domain
Tomoaki Nagasawa, Satoshi Ohya, Kazuki Sakamoto +2
We systematically formulate a hierarchy of isospectral Hamiltonians in one-dimensional supersymmetric quantum mechanics on an interval and on a circle, in which two successive Hami…
Spectroscopic Observations of WZ Sge-type Dwarf Novae, GW Lib and V455 And in Superoutburst
D. Nogami, K. Hiroi, Y. Suzuki +13
We carried out intensive spectroscopic observations of two WZ Sge-type dwarf novae, GW Lib, and V455 And during their superoutbursts in 2007, at 6 observatories. The observations c…
Taming the Leibniz Rule on the Lattice
Mitsuhiro Kato, Makoto Sakamoto, Hiroto So
We study a product rule and a difference operator equipped with Leibniz rule in a general framework of lattice field theory. It is shown that the difference operator can be determi…
Gauge-Fixing and Residual Symmetries in Gauge/Gravity Theories with Extra Dimensions
C. S. Lim, Tomoaki Nagasawa, Satoshi Ohya +2
We study compactified pure gauge/gravitational theories with gauge-fixing terms and show that these theories possess quantum mechanical SUSY-like symmetries between unphysical degr…
