1.
Lin R, Ramires A, Chitra R
Phys Rev Lett . 2024 Sep; 133(8):086001. PMID: 39241739
Driven-dissipative physics lie at the core of quantum optics. However, the full interplay between a driven quantum many-body system and its environment remains relatively unexplored in the solid state realm....

Heugel T, Chitra R, Eichler A, Zilberberg O
Phys Rev E . 2024 Jul; 109(6-1):064308. PMID: 39020932
Networks of nonlinear parametric resonators are promising candidates as Ising machines for annealing and optimization. These many-body out-of-equilibrium systems host complex phase diagrams of coexisting stationary states. The plethora of...

Sim K, Defenu N, Molignini P, Chitra R
Phys Rev Lett . 2023 Oct; 131(15):156501. PMID: 37897761
Non-Hermiticity in quantum Hamiltonians leads to nonunitary time evolution and possibly complex energy eigenvalues, which can lead to a rich phenomenology with no Hermitian counterpart. In this work, we study...

Paladugu V, Sreedhar S, Chitra R, Mannava S, Sreekumar S, Mangalakanthi J
J Obstet Gynaecol India . 2023 Mar; 73(1):28-35. PMID: 36879941
Background: Intrapartum fetal hypoxia which is one of the leading causes of neonatal morbidity and mortality is a preventable cause. Over the past years, many methods have been employed to...

Lin R, Rosa-Medina R, Ferri F, Finger F, Kroeger K, Donner T, et al.
Phys Rev Lett . 2022 May; 128(15):153601. PMID: 35499900
Three-level atomic systems coupled to light have the capacity to host dark states. We study a system of V-shaped three-level atoms coherently coupled to the two quadratures of a dissipative...

Rosa-Medina R, Ferri F, Finger F, Dogra N, Kroeger K, Lin R, et al.
Phys Rev Lett . 2022 Apr; 128(14):143602. PMID: 35476481
We report on the experimental realization and detection of dynamical currents in a spin-textured lattice in momentum space. Collective tunneling is implemented via cavity-assisted Raman scattering of photons by a...

Kumar K, Baliga G, Babu N, Rajan R, Kumar G, Mishra C, et al.
Indian J Ophthalmol . 2021 Oct; 69(11):3289-3295. PMID: 34708790
Purpose: To evaluate the clinical profile, visual outcomes, and complications among young adult patients with type 1 diabetes mellitus (insulin-dependent DM-T1DM) in comparison with patients with type 2 diabetes mellitus...

Frimmer M, Heugel T, Nosan Z, Tebbenjohanns F, Halg D, Akin A, et al.
Phys Rev Lett . 2020 Jan; 123(25):254102. PMID: 31922787
We experimentally demonstrate flipping the phase state of a parametron within a single period of its oscillation. A parametron is a binary logic element based on a driven nonlinear resonator....

Gowthaman V, Singh S, Dhama K, Ramakrishnan M, Malik Y, Murthy T, et al.
Virusdisease . 2019 Dec; 30(3):441-452. PMID: 31803812
Newcastle disease (ND) and avian influenza (AI) are economically important infectious diseases of poultry. Sometime, concomitant secondary viral/or bacterial infections significantly alters the pathobiology of ND and AI in poultry....

Heugel T, Biondi M, Zilberberg O, Chitra R
Phys Rev Lett . 2019 Nov; 123(17):173601. PMID: 31702226
We study a dissipative Kerr resonator subject to both single- and two-photon detuned drives. Beyond a critical detuning threshold, the Kerr resonator exhibits a semiclassical first-order dissipative phase transition between...
