Holographic Symmetry-Breaking Phases in AdS$_3$/CFT$_2$
Holographic Symmetry-Breaking Phases AdS$_3$/CFT$_2$
2010/12/23
In this note we study the symmetry-breaking phases of 3D gravity coupled to matter. In particular, we consider black holes with scalar hair as a model of symmetry-breaking phases of a strongly coupled...
Symmetry Breaking Phase Transitions in ABJM Theory with a Finite U(1) Chemical Potential
Phase Transitions ABJM Theory Finite U(1) Chemical Potential
2010/12/21
We consider the U(1) charged sector of ABJM theory at finite temperature, which corresponds
to the Reissner-Nordstrom AdS black hole in the dual type IIA supergravity description. Including back-reac...
Universal routes to spontaneous PT-symmetry breaking in non-hermitian quantum systems
Universal routes PT-symmetry non-hermitian quantum systems
2010/11/17
PT-symmetric systems can have a real spectrum even when their Hamiltonian is non-hermitian, but develop a complex spectrum when the degree of non-hermiticity increases. Here we utilize random-matrix ...
