Pressure-Tuned Metamagnetism and Emergent Three-Body Interactions in CsFeCl
K. Nihongi, T. Kida, Y. Narumi +11
We present a combined experimental and theoretical study of the triangular-lattice quantum antiferromagnet CsFeCl under high magnetic fields and high pressure. Pulsed-field mag…

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…

Melting of a Bosonic Mott Insulator in Kagome Optical Lattices with Sign-Inverted Hopping
Kazuma Nagao, Daisuke Yamamoto, Seiji Yunoki +1
Using the discrete truncated Wigner approximation (dTWA), we investigate the nonequilibrium dynamics of ultracold bosons confined in optical kagome lattices, focusing on both unfru…
