Quantum Sparse Coding
Yaniv Romano, Harel Primack, Talya Vaknin +5
The ultimate goal of any sparse coding method is to accurately recover from a few noisy linear measurements, an unknown sparse vector. Unfortunately, this estimation problem is NP-…
Universality of the nonphononic vibrational spectrum across different classes of computer glasses
David Richard, Karina González-López, Geert Kapteijns +4
It has been recently established that the low-frequency spectrum of simple computer glass models is populated by soft, quasilocalized nonphononic vibrational modes whose frequencie…
The TT* deformation at large central charge
Ofer Aharony, Talya Vaknin
We study Zamolodchikov's TT* deformation of two dimensional quantum field theories in a 't Hooft-like limit, in which we scale the number of degrees of freedom c to infinity and th…
Entanglement Entropy and Conformal Collider Physics in 2D CFTs
Talya Vaknin
We consider a conformal field theory in two dimensions in which an external perturbation is placed. We study the energy flux and entanglement entropy for one, two and multiple inte…
