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…
