Measurement-induced spatially nonuniform fluctuations of the local particle number and their crossover in a quasiperiodic free-fermion chain
Toranosuke Matsubara, Kazuki Yamamoto
We study continuously monitored dynamics of a quasiperiodic free-fermion chain defined on a Fibonacci lattice. We focus on fluctuations of the local particle number, which exhibit…
Modulated honeycomb lattices and their magnetic properties
Akihisa Koga, Toranosuke Matsubara
We propose a family of modulated honeycomb lattices, a class of quasiperiodic tilings characterized by the metallic mean. These lattices consist of six distinct hexagonal prototile…
Measurement-induced phase transitions for free fermions in a quasiperiodic potential
Toranosuke Matsubara, Kazuki Yamamoto, Akihisa Koga
We study the dynamics under continuous measurements for free fermions in a quasiperiodic potential by using the Aubry-André-Harper model with hopping rate and potential strengt…
Triangular and dice quasicrystals modulated by generic 1D aperiodic sequences
Toranosuke Matsubara, Akihisa Koga, Tomonari Dotera
We present a method for generating hexagonal aperiodic tilings that are topologically equivalent to the triangular and dice lattices. This approach incorporates aperiodic sequences…
Aperiodic approximants bridging quasicrystals and modulated structures
Toranosuke Matsubara, Akihisa Koga, Atsushi Takano +2
Aperiodic crystals constitute a fascinating class of materials that includes incommensurate (IC) modulated structures and quasicrystals (QCs). Although these two categories share a…
Ferromagnetically ordered states in the Hubbard model on the hexagonal golden-mean tiling
Toranosuke Matsubara, Akihisa Koga, Sam Coates
We study magnetic properties of the half-filled Hubbard model on the two-dimensional hexagonal golden-mean quasiperiodic tiling. The tiling is composed of large and small…
A three tile 6-fold golden-mean tiling
Sam Coates, Toranosuke Matsubara, Akihisa Koga
We present a multi-edge-length aperiodic tiling which exhibits 6--fold rotational symmetry. The edge lengths of the tiling are proportional to 1:, where is the golden mean $…
Confined states in the tight-binding model on the hexagonal golden-mean tiling
Toranosuke Matsubara, Akihisa Koga, Sam Coates
We study the tight-binding model with two distinct hoppings on the two-dimensional hexagonal golden-mean tiling and examine the confined states with , where i…
Hexagonal and trigonal quasiperiodic tilings
Sam Coates, Akihisa Koga, Toranosuke Matsubara +4
Exploring nonminimal-rank quasicrystals, which have symmetries that can be found in both periodic and aperiodic crystals, often provides new insight into the physical nature of ape…
