Universal crossovers in weakly-monitored quantum critical states
Abhishek Kumar, Rushikesh A. Patil, Andreas W. W. Ludwig +1
We study post-measurement ensembles of ground states of tricritical and critical 1D quantum Ising Hamiltonians subjected, respectively, to weak energy and spin measurements without…
Learning measurement-induced phase transitions using attention
Hyejin Kim, Abhishek Kumar, Yiqing Zhou +3
Measurement-induced phase transitions (MIPTs) epitomize new intellectual pursuits inspired by the advent of quantum hardware and the emergence of discrete and programmable circuit…
Random Quantum Circuits with Time-Reversal Symmetry
Kabir Khanna, Abhishek Kumar, Romain Vasseur +1
Time-reversal (TR) symmetry is crucial for understanding a wide range of physical phenomena, and plays a key role in constraining fundamental particle interactions and in classifyi…
Boundary transfer matrix spectrum of measurement-induced transitions
Abhishek Kumar, Kemal Aziz, Ahana Chakraborty +4
Measurement-induced phase transitions (MIPTs) are known to be described by non-unitary conformal field theories (CFTs) whose precise nature remains unknown. Most physical quantitie…
