Revisiting wormhole-induced global symmetry breaking
Kiyoharu Kawana
It is widely believed that global symmetries cannot exist in a consistent theory of quantum gravity. A prominent mechanism underlying this expectation is provided by gravitational…
Loop expansion in polymer field theory: application to phase separation
Kiyoharu Kawana, Kyosuke Adachi
Liquid-liquid phase separation underlies phenomena ranging from protein condensate formation to the phase coexistence of synthetic polymers. Although the random phase approximation…
Variational Method for Interacting Surfaces with Higher-Form Global Symmetries
Kiyoharu Kawana
We develop a variational method for interacting surface systems with higher-form global symmetries. As a natural extension of the conventional second-quantized Hamiltonian of inter…
Landau theory for lattice higher gauge theory and Kramers-Wannier duality
Kiyoharu Kawana
We derive a Landau field theory for a lattice higher gauge theory defined on -dimensional open cells (i.e., sites, links, faces, cubes, etc.), and study its continuum-limit and…
Phases and propagation of closed p-brane
Kiyoharu Kawana
We study phases and propagation of closed -brane within the framework of effective field theory with higher-form global symmetries, i.e., {\it brane-field theory}. We extend our…
On Virial Expansion in Hard Sphere Model
Kiyoharu Kawana
Virial expansion is a traditional approach in statistical mechanics that expresses thermodynamic quantities, such as pressure , as power series of density or chemical potential.…
