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…
Compressed sensing quantum state tomography for qudits: A comparison of Gell-Mann and Heisenberg-Weyl observable bases
Yoshiyuki Kakihara, Daisuke Yamamoto, Giacomo Marmorini
Quantum state tomography (QST) is an essential technique for reconstructing the density matrix of an unknown quantum state from measurement data, crucial for quantum information pr…
Measuring entanglement without local addressing in quantum many-body simulators via spiral quantum state tomography
Giacomo Marmorini, Takeshi Fukuhara, Daisuke Yamamoto
Quantum state tomography serves as a key tool for identifying quantum states generated in quantum computers and simulators, typically involving local operations on individual parti…
Rényi entropy of the permutationally invariant part of the ground state across a quantum phase transition
Yuki Miyazaki, Giacomo Marmorini, Nobuo Furukawa +1
We investigate the role of the permutationally invariant part of the density matrix (PIDM) in capturing the properties of the ground state of the system during a quantum phase tran…
Thermal Ising transition in two-dimensional SU(3) Fermi lattice gases with population imbalance
Hayato Motegi, Giacomo Marmorini, Nobuo Furukawa +1
We focus on three-component SU(3) Fermi gases loaded into a square optical lattice, with population imbalance between one component and the others. At strong coupling the system is…
Linear Flavor-Wave Analysis of SU(4)-Symmetric Tetramer Model with Population Imbalance
Yuki Miyazaki, Giacomo Marmorini, Nobuo Furukawa +1
We study the quantum magnetism of the SU(4) Mott insulator in a square optical superlattice, in which atoms with four nuclear-spin components strongly interact with each other, in…
