Kavli Affiliate: David Gross | First 5 Authors: Arne Heimendahl, Markus Heinrich, David Gross, , | Summary: Stabiliser operations occupy a prominent role in fault-tolerant quantum computing. They are defined operationally: by the use of Clifford gates, Pauli measurements and classical control. These operations can be efficiently simulated on a classical computer, a result which […]
Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Farzan Vafa, Mark J. Bowick, Boris I. Shraiman, M. Cristina Marchetti, | Summary: Recent experiments in various cell types have shown that two-dimensional tissues often display local nematic order, with evidence of extensile stresses manifest in the dynamics of topological defects. Using a mesoscopic model where […]
Kavli Affiliate: Bo Gu | First 5 Authors: Jing-Yang You, Bo Gu, Gang Su, , | Summary: Honeycomb or triangular lattices were extensively studied and thought to be proper platforms for realizing quantum anomalous Hall effect (QAHE), where magnetism is usually caused by d orbitals of transition metals. Here we propose that square lattice can […]
Kavli Affiliate: Shenghan Jiang | First 5 Authors: Brenden Roberts, Shenghan Jiang, Olexei I. Motrunich, , | Summary: We continue recent efforts to discover examples of deconfined quantum criticality in one-dimensional models. In this work we investigate the transition between a $mathbb{Z}_3$ ferromagnet and a phase with valence bond solid (VBS) order in a spin […]

Kavli Affiliate: Mark J. Bowick | First 5 Authors: Suraj Shankar, Anton Souslov, Mark J. Bowick, M. Cristina Marchetti, Vincenzo Vitelli | Summary: Active matter encompasses different nonequilibrium systems in which individual constituents convert energy into non-conservative forces or motion at the microscale. This review provides an elementary introduction to the role of topology in […]
Kavli Affiliate: Leon Balents | First 5 Authors: Kasra Hejazi, Zhu-Xi Luo, Leon Balents, , | Summary: We study untwisted heterobilayers of ferromagnetic and antiferromagnetic van der Waals materials, with in particular a Dzyaloshinskii-Moriya interaction in the ferromagnetic layer. A continuum low energy field theory is utilized to study such systems. We develop a phase […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Zheng Zhu, D. N. Sheng, Ashvin Vishwanath, , | Summary: We investigate the evolution of the Mott insulators in the triangular lattice Hubbard Model, as a function of hole doping $delta$ in both the strong and intermediate coupling limits. Using the advanced density matrix renormalization group (DMRG) […]
Kavli Affiliate: Boris I. Shraiman | First 5 Authors: Farzan Vafa, Mark J. Bowick, M. Cristina Marchetti, Boris I. Shraiman, | Summary: Recent experiments and numerical studies have drawn attention to the dynamics of active nematics. Two-dimensional active nematics flow spontaneously and exhibit spatiotemporal chaotic flows with proliferation of topological defects in the nematic texture. […]
