The spectrum of single-trace operators of order-one dimension, of holographic CFTs at strong coupling and large N, can be mapped to the spectrum of Kaluza-Klein (KK) excitations over the dual AdS supergravity solutions. Computing these KK spectra is...

In the inner Milky Way stars trek together in a bar-shaped, rotating overdensity: the central bar, which dominates the inner disc out half-way to the Sun. The rotation velocity/pattern speed of this bar has been intensely debated. The best insight...

Linear dynamical systems are the canonical model for time series data. They have wide-ranging applications and there is a vast literature on learning their parameters from input-output sequences. Moreover they have received renewed interest because...

The density of states of a unitary conformal field theory is known to have a universal behavior at high energy. In two dimensions, this behavior is described by the Cardy formula. If the theory has symmetry, it is interesting to understand the...
