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: 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. […]

Kavli Affiliate: Matthew P. A. Fisher | First 5 Authors: Yaodong Li, Xiao Chen, Andreas W. W. Ludwig, Matthew P. A. Fisher, | Summary: We establish the emergence of a conformal field theory (CFT) in a (1+1)-dimensional hybrid quantum circuit right at the measurement-driven entanglement transition by revealing space-time conformal covariance of entanglement entropies and […]
Kavli Affiliate: David Gross | First 5 Authors: Jonas Haferkamp, Felipe Montealegre-Mora, Markus Heinrich, Jens Eisert, David Gross | Summary: Many quantum information protocols require the implementation of random unitaries. Because it takes exponential resources to produce Haar-random unitaries drawn from the full $n$-qubit group, one often resorts to $t$-designs. Unitary $t$-designs mimic the Haar-measure […]
Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Motivated by $Tbar T$, we introduce and study a wide class of solvable deformations of quantum-mechanical theories. These deformations map the Hamiltonian to a function of itself. We solve these theories by computing all finite-temperature […]

Kavli Affiliate: David J. Gross | First 5 Authors: David J. Gross, Jorrit Kruthoff, Andrew Rolph, Edgar Shaghoulian, | Summary: Quantum field theory in zero spatial dimensions has a rich infrared landscape and a universal ultraviolet, inverting the usual Wilsonian paradigm. For holographic theories this implies a rich landscape of asymptotically AdS$_2$ geometries. Isolating the […]
