Bulk-Measurement-Induced Boundary Phase Transition in Toric Code and Gauge-Higgs Model
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
Study of boundary phase transition in toric code under cylinder geometry via bulk projective measurement is reported. As the frequency of local measurement for bulk qubits is incre…
Blocking particle dynamics in diamond chain with spatially increasing flux
Tomonari Mizoguchi, Yoshihito Kuno, Yasuhiro Hatsugai
Spatial non-uniformity in tight-binding models serves as a source of rich phenomena. In this paper, we study a diamond-chain tight-binding model with a spatially-modulated magnetic…
Phase transition and evidence of fast-scrambling phase in measurement-only quantum circuit
Yoshihito Kuno, Takahiro Orito, Ikuo Ichinose
Information scrambling is nowadays one of the most important topics in various fields of research. Measurement-only circuit (MoC) exhibits specific information scrambling dynamics,…
symmetry and Berry phase of bosonic ladder
Yoshihito Kuno, Yasuhiro Hatsugai
Bose gas on a two-leg ladder exhibits an interesting topological phase. We show the presence of a bosonic symmetry-protected-topological (SPT) phase protected by sy…
Interplay between lattice gauge theory and subsystem codes
Yoshihito Kuno, Ikuo Ichinose
It is now widely recognized that the toric code is a pure gauge-theory model governed by a projective Hamiltonian with topological orders. In this work, we extend the interplay bet…
Production of lattice gauge-Higgs topological states in measurement-only quantum circuit
Yoshihito Kuno, Ikuo Ichinose
By imaginary-time evolution with Hamiltonian, an arbitrary state arrives in the system's ground state. In this work, we conjecture that this dynamics can be simulated by measuremen…
