A fractionalised "" classical Heisenberg spin liquid
J. Rehn, Arnab Sen, R. Moessner
Quantum spin systems are by now known to exhibit a large number of different classes of spin liquid phases. By contrast, for \textit{classical} Heisenberg models, only one kind of…
Level spectroscopy in a two-dimensional quantum magnet: Linearly dispersing spinons at the deconfined quantum critical point
Hidemaro Suwa, Arnab Sen, Anders W. Sandvik
We study the level structure of excitations at the "deconfined" critical point separating antiferromagnetic and valence-bond-solid phases in two-dimensional quantum spin systems us…
Eigenstate Gibbs Ensemble in Integrable Quantum Systems
Sourav Nandy, Arnab Sen, Arnab Das +1
The Eigenstate Thermalization Hypothesis implies that for a thermodynamically large system in one of its eigenstates, the reduced density matrix describing any finite subsystem is…
Signatures and conditions for phase band crossings in periodically driven integrable systems
Bhaskar Mukherjee, Arnab Sen, Diptiman Sen +1
We present generic conditions for phase band crossings for a class of periodically driven integrable systems represented by free fermionic models subjected to arbitrary periodic dr…
Double roots of random polynomials with integer coefficients
Ohad N. Feldheim, Arnab Sen
We consider random polynomials whose coefficients are independent and identically distributed on the integers. We prove that if the coefficient distribution has bounded support and…
