Extreme statistics of the excitations in the random transverse Ising chain
István A. Kovács, Tamás Pető, Ferenc Iglói
In random quantum magnets, like the random transverse Ising chain, the low energy excitations are localized in rare regions and there are only weak correlations between them. It is…
Emergence of disconnected clusters in heterogeneous complex systems
István A. Kovács, Róbert Juhász
Percolation theory dictates an intuitive picture depicting correlated regions in complex systems as densely connected clusters. While this picture might be adequate at small scales…
A Centralized and Scalable Uplink Power Control Algorithm in Low SINR Scenarios
Xuesong Cai, István Kovács, Jeroen Wigard +1
Power control is becoming increasingly essential for the fifth-generation (5G) and beyond systems. An example use-case, among others, is the unmanned-aerial-vehicle (UAV) communica…
Computationally efficient transfinite patches with fullness control
Péter Salvi, István Kovács, Tamás Várady
Transfinite patches provide a simple and elegant solution to the problem of representing non-four-sided continuous surfaces, which are useful in a variety of applications, such as…
The group is a DCI-group
István Kovács, Grigory Ryabov
We prove that the group is a DCI-group for distinct primes and , that is, two Cayley digraphs over are isomorphic if and only if their c…
Entanglement entropy of random partitioning
Gergö Roósz, István A. Kovács, Ferenc Iglói
We study the entanglement entropy of random partitions in one- and two-dimensional critical fermionic systems. In an infinite system we consider a finite, connected (hypercubic) do…
