Quantum Spin Liquids Stabilized by Disorder in Non-Kramers Pyrochlores
Marcus V. Marinho, Eric C. Andrade
We investigate the emergence of quantum spin liquid phases in pyrochlore oxides with non-Kramers ions, in which structural randomness effectively acts as a transverse field, introd…

Kondo screening and random-singlet formation in highly disordered systems
Lucas G. Rabelo, Igor C. Almeida, Eduardo Miranda +2
We propose a minimal model to capture the anomalous low-temperature thermodynamics of doped semiconductors, such as Si:P, across the metal-insulator transition. We consider pairs o…

Partons from stabilizer codes
Rafael A. Macedo, Carlo C. Bellinati, Weslei B. Fontana +2
The Gutzwiller projection of fermionic wave functions is a well-established method for generating variational wave functions describing exotic states of matter, such as quantum spi…
