Emergent Spin Supersolids in Frustrated Quantum Materials
Yixuan Huang, Seiji Yunoki, Sadamichi Maekawa
Recent years have witnessed the emergence of spin supersolids in frustrated quantum magnets, establishing a material-based platform for supersolidity beyond its original context in…
A sine-square deformation approach to quantum critical points in one-dimensional systems
Yuki Miyazaki, Shiori Tanigawa, Giacomo Marmorini +2
We propose a method to determine the quantum phase boundaries of one-dimensional systems using sine-square deformation (SSD). Based on the proposition, supported by several exactly…
Low-energy photoexcitations inside the Mott gap in doped Hubbard and t-J ladders
Sumal Chandra, Kazuya Shinjo, Shigetoshi Sota +2
We investigate changes in the optical conductivity of doped Mott insulators by tuning ultrashort pump pulses to target either the Drude or low-energy absorption regions. Using a ho…
Dissipationless dynamics of spin supersolid states in a spin-1/2 triangular antiferromagnet with impurities
Yixuan Huang, Yuan Gao, Wei Li +2
Motivated by recent experimental evidence for spin supersolid states in triangular-lattice compounds, we numerically investigate the dynamical properties of magnetic field-induced…
Unified description of cuprate superconductors by fractionalized electrons emerging from integrated analyses of photoemission spectra and quasiparticle interference
Shiro Sakai, Youhei Yamaji, Fumihiro Imoto +6
Electronic structure of high-temperature superconducting cuprates is studied by analyzing experimental data independently obtained from two complementary spectroscopies, one, quasi…
Probabilistic imaginary-time evolution in state-vector-based and shot-based simulations and on quantum devices
Satoshi Ejima, Kazuhiro Seki, Benedikt Fauseweh +1
Imaginary-time evolution, an important technique in tensor network and quantum Monte Carlo algorithms on classical computers, has recently been adapted to quantum computing. In thi…
