论文摘要
我们提出了一个新的无限型IIB背景家族，并带有广告$ _2 $ factor，保留$ {\ cal n} = 4 $ susy。对于家庭的每个成员，我们提出了精确的双重超超同源量子力学（SCQM）。我们为真空的数量（“中央电荷”），Chern-Simons项和SCQM的其他非扰动方面提供全息表达。我们将一维系统的“中央电荷”与IIB型电气和磁通量的组合相结合。 Ramond-Ramond通量用于提出中央电荷的极端原理。分析了这些共形量子力学的其他物理和几何方面。
We present a new infinite family of Type IIB backgrounds with an AdS$_2$ factor, preserving ${\cal N}=4$ SUSY. For each member of the family we propose a precise dual Super Conformal Quantum Mechanics (SCQM). We provide holographic expressions for the number of vacua (the "central charge"), Chern-Simons terms and other non-perturbative aspects of the SCQM. We relate the "central charge" of the one-dimensional system with a combination of electric and magnetic fluxes in Type IIB. The Ramond-Ramond fluxes are used to propose an extremisation principle for the central charge. Other physical and geometrical aspects of these conformal quantum mechanics are analysed.
