A separation of out-of-time-ordered correlator and entanglement
The out-of-time-ordered correlator (OTOC) and entanglement are two physically motivated and widely used probes of the ``scrambling'' of quantum information, which has drawn great interest recently in quantum gravity and...

Deformations of 4d SCFTs and Supersymmetry Enhancing RG Flows
We study remarkable RG flows in 4d QFT where supersymmetry enhances from N=1 to N=2 in the IR. This is triggered by the N=1 preserving deformation of 4d N=2 SCFTs...

Polarization measured by magnetic monopole and boundary Luttinger theorem
We develop a topological approach to bulk polarization of electric insulators in d>1 dimensions. We define polarization through topological Theta terms involving background gauge fields of the U(1) charge conservation...

Randomness Compression in Networks
Randomness is a valuable resource in both classical and quantum networks and we wish to generate desired probability distributions as cheaply as possible. If we are allowed to slightly change...

Order by Singularity
We present a paradigm for effective descriptions of quantum magnets. Typically, a magnet has many classical ground states — configurations of spins (as classical vectors) that have the least energy...
