Topological Defects and Cosmology [PDF]

, 1998
Many particle physics models of matter admit solutions corresponding to stable or long-lived topological defects. In the context of standard cosmology it is then unavoidable that such defects will form during phase transitions in the very early Universe.

A general holographic insulator/superconductor model with dark matter sector away from the probe limit

Nuclear Physics B, 2017
We investigate holographic phase transitions with dark matter sector in the AdS soliton background away from the probe limit. In cases of weak backreaction, we find that the larger coupling parameter α makes the gap of condensation shallower and the ...

A geometric proof of the equality between entanglement and edge spectra

, 2011
The bulk-edge correspondence for topological quantum liquids states that the spectrum of the reduced density matrix of a large subregion reproduces the thermal spectrum of a physical edge.

On the definition of entanglement entropy in lattice gauge theories [PDF]

, 2015
We focus on the issue of proper definition of entanglement entropy in lattice gauge theories, and examine a naive definition where gauge invariant states are viewed as elements of an extended Hilbert space which contains gauge non-invariant states as ...

Dynamical changes of the polar cap potential structure: an information theory approach [PDF]

Nonlinear Processes in Geophysics, 2011
Some features, such as vortex structures often observed through a wide spread of spatial scales, suggest that ionospheric convection is turbulent and complex in nature.

Measuring entanglement entropy of a generic many-body system with a quantum switch

, 2012
Entanglement entropy has become an important theoretical concept in condensed matter physics, because it provides a unique tool for characterizing quantum mechanical many-body phases and new kinds of quantum order.

Synchrotron Radiation for Quantum Technology

Advanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Topology by Design in Magnetic nano-Materials: Artificial Spin Ice

, 2017
Artificial Spin Ices are two dimensional arrays of magnetic, interacting nano-structures whose geometry can be chosen at will, and whose elementary degrees of freedom can be characterized directly.

Long-range Ising and Kitaev Models: Phases, Correlations and Edge Modes [PDF]

, 2015
We analyze the quantum phases, correlation functions and edge modes for a class of spin-1/2 and fermionic models related to the 1D Ising chain in the presence of a transverse field.
