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…
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…
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…
Local spin-flip transitions induced by magnetic quantum impurities in two-dimensional magnets
Tim Bauer, Lucas R. D. Freitas, Eric C. Andrade +2
We predict a general local spin-flip transition mechanism caused by magnetic quantum impurities in (partially) polarized phases of quantum magnets in the absence of conservation la…
Electronic Griffiths phase of the d=2 Mott transition
E. C. Andrade, E. Miranda, V. Dobrosavljevic
We investigate the effects of disorder within the T=0 Brinkman-Rice (BR) scenario for the Mott metal-insulator transition (MIT) in two dimensions (2d). For sufficiently weak disord…
