Emergent Hawking Radiation and Quantum Sensing in a Quenched Chiral Spin Chain
Nitesh Jaiswal, S. Shankaranarayanan
We investigate the emergence and detection of Hawking radiation (HR) in a 1D chiral spin chain model, where the gravitational collapse is simulated by a sudden quantum quench that…
Analog charged black hole formation via percolation: Exploring cosmic censorship and Hoop conjecture
Nitesh Jaiswal, S. Shankaranarayanan
We investigate an analog model of charged black hole (BH) formation using the framework of classical percolation. By analyzing the scaling behavior of key quantities, including sur…
Spread complexity evolution in quenched interacting quantum systems
Mamta Gautam, Kunal Pal, Kuntal Pal +3
We analyse time evolution of spread complexity (SC) in an isolated interacting quantum many-body system when it is subjected to a sudden quench. The differences in characteristics…
Spread Complexity in free fermion models
Mamta Gautam, Nitesh Jaiswal, Ankit Gill
We study spread complexity and the statistics of work done for quenches in the three-spin interacting Ising model, the XY spin chain, and the Su-Schrieffer-Heeger model. We study t…
FOTOC complexity in an extended Lipkin-Meshkov-Glick model
Nitesh Jaiswal, Mamta Gautam, Ankit Gill +1
We study fidelity out-of-time-order correlators (FOTOCs) in an extended Lipkin-Meshkov-Glick model and demonstrate that these exhibit distinctive behaviour at quantum phase transit…
Complexity and quenches in models with three and four spin interactions
Mamta Gautam, Nitesh Jaiswal, Ankit Gill +1
We study information theoretic quantities in models with three and four spin interactions. These models show distinctive characteristics compared to their nearest neighbour counter…
Complexity, Information Geometry, and Loschmidt Echo near Quantum Criticality
Nitesh Jaiswal, Mamta Gautam, Tapobrata Sarkar
We consider the Nielsen complexity , the Loschmidt echo , and the Fubini-Study complexity in the transverse XY model, following a sudden quantum q…
Complexity and information geometry in spin chains
Nitesh Jaiswal, Mamta Gautam, Tapobrata Sarkar
We study Nielsen complexity and Fubini-Study complexity for a class of exactly solvable one dimensional spin systems. Our examples include the transverse XY spin chain and its natu…
