Inequality for Strong-Weak Spontaneous Symmetry Breaking in Fermionic Open Quantum systems
Abhijat Sarma, Cenke Xu
Under decoherence, an initial Gaussian (free-fermion) state evolves into a non-Gaussian mixed state, so the resulting decohered fermionic state is not exactly solvable in general.…

Probing Defects with Quantum Simulator Snapshots
Abhijat Sarma, Nayan Myerson-Jain, Yue Liu +4
Snapshots, i.e. projective measurements of local degrees of freedom, are the most standard data taken in experiments on quantum simulators. Snapshots are usually used to probe loca…
