Investigating flow facilitated by art-making, and potential implications on identity, conflict and wellbeing
… the facilitation, experience and measurement of flow (Csikszentmihaly, 1979), and group flow in particular, through individual and collaborative creating and to note the potential implications of this for identity, wellbeing and conflict. Previous research on group flow facilitated by …

Shared Creativity and Flow in Dance Improvisation Practice
… shared creative processes and the role of flow experience in group dance improvisation. A literature review suggested that dancers associate high-quality performance with 'being in the flow', and that group flow is a peak experience when a group is performing at its highest level. The first …

Aspects of Topological Sigma Models
… analyzed and related via renormalization group flow to correlation functions in topological conformal field theories. In particular, the methods may well shed light on the somewhat mysterious origin of operators corresponding to non-toric Kahler deformations---operators that arise in …

Asymptotically Safe Gravity: from spacetime foliation to cosmology
… Point (NGFP) of the underlying renormalization group flow. The high-energy modifications of gravity resulting from the scaling of couplings around the NGFP may have profound implications in astrophysics and cosmology. The Functional Renormalization Group (FRG) constitutes an ideal tool to …

Studies of superconformal field theories using GLSM and conformal bootstrap
… identity arises. Under the renormalization group flow, we argue that these models flow into superconformal fixed points describing string theory compactifications backgrounds with non-trivial H-flux turned on. By analyzing quantum-consistency of effective theories with such mechanism, we …

Ground state and thermal dynamics of strong interaction
… dynamics, we derive renormalization group flow equations in next to leading order in the derivative expansion that go beyond the leading renormalizable couplings and include the entire bosonic field dependence. We examine these flow equations both in there general form that includes …

Studies in random Ising spin systems
… model. The phenomenological renormalization group and the transfer-matrix method are generalized to random systems and applied to the random-bond Ising model, also called the Edwards-Anderson spin-glass model. Results show that the two-dimensional Edwards-Anderson model has a spin-glass …

Aspects of Non-Perturbative Renormalization
… methods, we use the differential renormalization group approach, particularly the Wegner-Houghton and the Polchinski renormalization group equations, in order to investigate the renormalization of a one-component periodic scalar field theory. The Wegner-Houghton equation provides a resummation of …

Two topics in non-perturbative lattice field theories : the U(1) quantum link model and perfect actions for scalar theories
… first part we discuss aspects of renormalization group flow and non-perturbative improvement of actions for scalar theories regularized on a lattice. We construct a perfect action, an action which is free of lattice artifacts, for a given theory. It is shown how a good approximation to the perfect …

Renormalization for insulating states of matter
… procedure where the conventional renormalization group scheme is not simply applicable. The first subject is the spectral weight structure of hole-doped Mott insulators. As the mixing between two separate Hubbard bands is dynamically generated, additional charge degrees of freedom is required to …

Critical dynamics of active phase separation: A scalar field theory approach
… literature. This system has an Renormalization Group flow that, to one loop, shows a strong coupling regime in and above its critical dimension d_c = 2 that was not present in the previous systems considered to model this physical process. This strong coupling regime is also explored …

PROBING THE NATURE OF COMPACT OBJECTS: SCATTERING, TIDES AND QUASINORMAL MODES
… tidal response via classical renormalization group flow. We also extend this approach to NSs, and extract electric, quadrupolar, Love and dissipation numbers from the Raman amplitude as a function of the boundary conditions for the metric perturbations at the stellar surface, that are …
