Non-commutative mechanics and Exotic Galilean symmetry
Non-commutative mechanics Exotic Galilean symmetry
2010/12/23
In order to derive a large set of Hamiltonian dynamical systems, but with only first order Lagrangian, we resort to the formulation in terms of Lagrange-Souriau 2-form formalism. A wide class of syste...
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...
Breaking the $Z_2$ symmetry of the Randall-Sundrum scenario and the fate of the massive modes
the Randall-Sundrum scenario the fate of the massive modes
2010/12/23
We address in detail the issue of possible resonances in the massive modes on a brane without reflection symmetry. After identifying a set of solvability conditions, we show explicitly how the modes o...
We show that an interacting spin-0 field on a de Sitter space background will break the underlying de Sitter symmetry. This is done first for a (1+1) de Sitter space where a boson-fermion corresponde...
When combined with mirror symmetry, the A-model approach to quantization leads to a fairly simple and tractable problem. The most interesting part of the problem then becomes finding the mirror of the...
We show that a certain class of light-like Wilson loops exhibits a Yangian symmetry at one loop, or equivalently, in an Abelian theory. The Wilson loops we discuss are equivalent to one-loop MHV ampl...
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...
Density models for streamer discharges: beyond cylindrical symmetry and homogeneous media
cylindrical symmetry homogeneous media
2010/11/16
Streamer electrical discharges are often investigated with computer simulations of density models (also called drift-diffusion-reaction models). We review these models, detailing their physical found...
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 ...
Generalized Dirac bracket and the role of the Poincaré symmetry in the program of canonical quantization of fields 1
Generalized Dirac bracket Poincaré symmetry program of canonical quantization
2010/11/11
An elementary presentation of the methods for the canonical quantization of constraint systems with Fermi variables is given. The emphasis is on the subtleties of the construction of an appropriate cl...
Entanglement and symmetry effects in the transition to the Schroedinger cat regime
Entanglement symmetry effects transition Schroedinger cat regime
2010/11/5
We study two-spin entanglement and order parameter fluctuations as a function of the system size in the XY model in a transverse field and in the isotropic XXX model. Both models are characterized by ...
