This review starts with the basic Hilbert space structure for continuous variable systems, explaining the pre-requisites
to be able to define a Gaussian state. After that a preliminary study of Gaussian channels is ...

The study of spin liquids, an exotic phase of matter, is a rapidly growing field. Spin Liquids are, by
definition, pure Mott insulators which, due to quantum fluctuations and frustration, lack magnetic
order even at the ...

Surface defects in gauge theories are non-local operators supported on co-dimension
two sub manifold. Defects in quantum field theory can provide us with important non-
perturbative information eg. di↵erent phase structures ...
