Neural scaling laws and evolution of learnable activation functions of Kolmogorov-Arnold networks
Tilen Cadez, Sanghoon Lee, Kyoung-Min Kim
Kolmogorov-Arnold Networks (KANs) represent a compelling alternative to traditional Multi-Layer Perceptron (MLP)-based neural networks. By employing activation functions as learnab…
Marked vertex search on disordered graphs with Rosenzweig-Porter phases
Sabyasachi Chakraborty, Tilen Cadez, Sonjoy Majumder +1
Quantum marked vertex search algorithms are known to outperform their classical counterparts, yet their behavior in the presence of disorder remains largely unexplored. Here, we ad…
Emergence of chiral -wave and -wave states in -wave altermagnets
Tilen Cadez, Abraham Nathan Sunanta, Kyoung-Min Kim
Altermagnets emerge as a novel platform for realizing unconventional superconductivity through their exotic momentum-dependent spin-splitting of electronic band structures. Recent…
Structural constraints on mobility edges in one-dimensional quasiperiodic systems
Sanghoon Lee, Tilen Cadez, Kyoung-Min Kim
Mobility edges commonly arise in one-dimensional quasiperiodic systems once exact self-duality is broken, yet their origin is typically understood only at the level of individual H…
Nonrelativistic versus relativistic quantum scars in billiard systems
Barbara Dietz, Dung Xuan Nguyen, Tilen Čadež
We study the features of scarred eigenstates of relativistic neutrino billiards (NBs), graphene billiards (GBs) and Haldane graphene billiards (HGBs) and recapitulate those for non…
Neural Scaling Laws for Deep Regression
Tilen Cadez, Kyoung-Min Kim
Neural scaling laws--power-law relationships between generalization errors and characteristics of deep learning models--are vital tools for developing reliable models while managin…

Meng Sun, Tilen Čadež, Igor Yurkevich +1
We study the interplay between quasi-periodic disorder and superconductivity in a 1D tight-binding model with the quasi-periodic modulation of on-site energies that follow the Fibo…
Machine learning wave functions to identify fractal phases
Tilen Cadez, Barbara Dietz, Dario Rosa +3
We demonstrate that an image recognition algorithm based on a convolutional neural network provides a powerful procedure to differentiate between ergodic, non-ergodic extended (fra…
Flat Band Induced Metal-Insulator Transitions for Weak Magnetic Flux and Spin-Orbit Disorder
Yeongjun Kim, Tilen Čadež, Alexei Andreanov +1
We consider manifolds of tunable all-band flat (ABF) lattices in dimensions d = 1, 2, parametrized by a manifold angle parameter θ. We study localization properties of eigenstates…
Delayed Thermalization in Mass-Deformed SYK
Dillip Kumar Nandy, Tilen Cadez, Barbara Dietz +2
We study the thermalizing properties of the mass-deformed SYK model, in a regime of parameters where the eigenstates are ergodically extended over just portions of the full Fock sp…
Metal-insulator transition in infinitesimally weakly disordered flatbands
Tilen Cadez, Yeongjun Kim, Alexei Andreanov +1
We study the effect of infinitesimal onsite disorder on d-dimensional all bands flat lattices. The lattices are generated from diagonal Hamiltonians by a sequence of (d + 1) local…
