Kavli Affiliate: Long Zhang | First 5 Authors: Yuejiu Zhao, Long Zhang, , , | Summary: Quenched disorders can strongly influence the physical properties of quantum many-body systems. The real-space strong-disorder renormalization group (SDRG) analysis has shown that the spin-1/2 random Heisenberg chain is controlled by the infinite-randomness fixed point (IRFP) and forms a random […]

Kavli Affiliate: Matthew Fisher | First 5 Authors: Manuel Ladron de Guevara, Matthew Fisher, Aaron Hertzmann, , | Summary: We introduce a novel image-to-painting method that facilitates the creation of large-scale, high-fidelity paintings with human-like quality and stylistic variation. To process large images and gain control over the painting process, we introduce a segmentation-based painting […]
Kavli Affiliate: Gang Su | First 5 Authors: Xing-Zhou Qu, Dai-Wei Qu, Wei Li, Gang Su, | Summary: The intriguing interplay between the two $e_g$ orbitals in the high-$T_c$ nickelate superconductor La$_3$Ni$_2$O$_7$ is studied via the density matrix renormalization group (DMRG) and finite-$T$ thermal tensor-network calculations. We consider a bilayer $t$-$J$ model that incorporates both […]
Kavli Affiliate: Zheng Zhu | First 5 Authors: Arda Demirhan, Jacob Miller, Yixu Qiu, Thomas J. Tucker, Zheng Zhu | Summary: We treat the problem of finding transitive subgroups G of S_n containing normal subgroups N_1 and N_2, with N_1 transitive and N_2 not transitive, such that G/N_1 is isomorphic G/N_2. We show that such […]
Kavli Affiliate: Gang Su | First 5 Authors: Xiang Li, Jia-Wen Li, Jing-Yang You, Gang Su, Bo Gu | Summary: Doping nonmagnetic semiconductors with magnetic impurities is a feasible way to obtain diluted magnetic semiconductors (DMSs). It is generally accepted that for the most extensively studied DMS, (Ga, Mn)As, its highest Curie temperature T$_{text{C}}$ was […]
Kavli Affiliate: Gang Su | First 5 Authors: Shi-Ju Ran, Gang Su, , , | Summary: It is a critical challenge to simultaneously gain high interpretability and efficiency with the current schemes of deep machine learning (ML). Tensor network (TN), which is a well-established mathematical tool originating from quantum mechanics, has shown its unique advantages […]
Kavli Affiliate: Rudolf Podgornik | First 5 Authors: Sunita Kumari, Rudolf Podgornik, , , | Summary: We present a derivation of the screening length for a solution containing a charge regulated macroion, e.g. protein, with its counterions. We show that it can be obtained directly from the second derivatives of the total free energy by […]
Kavli Affiliate: Lars Bildsten | First 5 Authors: Tin Long Sunny Wong, Lars Bildsten, , , | Summary: RCB stars are $Lapprox10^4,L_{odot}$ solar-mass objects that can exhibit large periods of extinction from dust ejection episodes. Many exhibit semiregular pulsations in the range of $30-50$ days with semi-amplitudes of $0.05-0.3$ magnitude. Space-based photometry has discovered that […]
Kavli Affiliate: David Gross | First 5 Authors: Sabrina Ammann, Maximilian Hess, Debora Ramacciotti, Sándor P. Fekete, Paulina L. A. Goedicke | Summary: In recent years, strong expectations have been raised for the possible power of quantum computing for solving difficult optimization problems, based on theoretical, asymptotic worst-case bounds. Can we expect this to have […]
