Hidden Yangian symmetry in sigma model on squashed sphere
Io Kawaguchi, Kentaroh Yoshida
We discuss a hidden symmetry of a two-dimensional sigma model on a squashed S^3. The SU(2) current can be improved so that it can be regarded as a flat connection. Then we can obta…
Semiclassical Analysis of M2-brane in AdS_4 x S^7 / Z_k
Makoto Sakaguchi, Hyeonjoon Shin, Kentaroh Yoshida
We start from the classical action describing a single M2-brane on AdS_4 x S^7/ Z_k and consider semiclassical fluctuaitions around a static, 1/2 BPS configuration whose shape is A…
Universal description of viscoelasticity with foliation preserving diffeomorphisms
Tatsuo Azeyanagi, Masafumi Fukuma, Hikaru Kawai +1
We review our recent proposal for a universal description of generic single-component viscoelastic systems with a single relaxation time. Foliation preserving diffeomorphisms are i…
