Topological properties and Majorana Multiplicity in Zigzag Kitaev Chain
Rajiv Kumar, Panch Ram, Levan Chotorlishvili +1
We investigate the spectral and topological properties of a zigzag Kitaev chain constructed from two diagonally coupled one dimensional Kitaev chains with a zero and finite superco…
Hopf bifurcation and stochastic spiking in an antiferromagnetic FitzHugh--Nagumo normal form
D. Maroulakos, A. Wal, I. Tralle +2
Antiferromagnets offer ultrafast, stray-field-free dynamics that are attractive for neuromorphic spintronic devices. Here we analyze an antiferromagnetic spin-Hall nano-oscillator…
Majorana bound states in a hybrid Kitaev ladder with long-range pairing
Rajiv Kumar, Tapan Mishra, Levan Chotorlishvili +1
We investigate an inter-leg coupled hybrid Kitaev ladder composed of two parallel superconducting chains with distinct pairing interactions. The upper chain of the ladder hosts con…
Quantum memory and scrambling from the perspective of a classical neural network
Dimitrios Maroulakos, Andrzej Wal, Marcin Kowalik +4
Entropic uncertainty relations are universal quantifiers of fundamental uncertainties of quantum measurements and are widely discussed in the quantum metrology literature. Quantum…
Entanglement between quantum dots transmitted via Majorana wire: Insights from the fermionic negativity, concurrence and quantum mutual information
C. Jasiukiewicz, A. Sinner, I. Weymann +2
We study quantum entanglement in a system comprising two quantum dots interconnected through the short topological superconducting nanowire, which hosts overlapping boundary Majora…
Quantum Skyrmion Qudit in a Triangular-lattice magnet
D. Maroulakos, A. Wal, A. Ugulava +2
Since the pioneering work Lohani et. al., Phys. Rev. X 9, 041063 (2019), it became clear that quantum skyrmions have highly unusual properties as compared to the classical skyrmion…
Relativistic quantum entanglement in a bipartite charged scalar system
T. Nadareishvili, S. Stagraczyński, L. Chotorlishvili
Continuous variable entanglement in a system of two interacting charged scalar mesons is studied. The mesons mutual interaction is mediated by a central symmetric Coulomb potential…
Majorana Signatures in the Tripartite Uncertainty Relations with Quantum Memory
D. Maroulakos, C. Jasiukiewicz, A. Wal +4
Quantumness imposes a fundamental limit on measurement accuracy. The paradigmatic cases are Heisenberg's uncertainty relation in the original formulation, Robertson's formulation,…
Two-level atom witness of thermalization of multimode optical fibers
M. Wanic, R. Khomeriki, S. Stagraczynski +3
In the present project, we study the dynamics of the two-level system coupled with the multimode optical system. In particular, we considered a square lattice of optical fibers. We…
The controlled rotation of entanglement in altermagnets
M. Kulig, T. Maslowski, K. A. Kouzakov +6
Altermagnetism became very popular because of unique features, namely coupling between magnetic properties and momentum of itinerant electrons. The particular model of the altermag…
Prethermal Floquet time crystals in chiral multiferroic chains and applications as quantum sensors of AC fields
Rohit Kumar Shukla, Levan Chotorlishvili, Sunil K. Mishra +1
We study the emergence of prethermal Floquet Time Crystal (pFTC) in disordered chiral multiferroic chains. The model is an extension of the usual periodically driven nearest-neighb…
Entanglement properties of photon-magnon crystal from nonlinear perspective
M. Wanic, C. Jasiukiewicz, Z. Toklikishvili +5
Quantifying the entanglement between two continuous bosonic modes, such as magnons and photons, is not trivial. The logarithmic negativity, calculated through the quantum Langevin…
Plasmonic skyrmion quantum thermodynamics
Vipin Vijayan, L. Chotorlishvili, A. Ernst +3
The primary obstacle in the field of quantum thermodynamics revolves around the development and practical implementation of quantum heat engines operating at the nanoscale. One of…
Topological entanglement entropy to identify topological order in quantum skyrmions
Vipin Vijayan, L. Chotorlishvili, A. Ernst +3
We study the topological entanglement entropy and scalar chirality of a topologically ordered skyrmion formed in a two-dimensional triangular lattice. Scalar chirality remains a sm…
